Male Specific -Testosterone issues:

“All three (chemical) sunscreens were detectable in urine... differences in testosterone levels were observed between the 2 weeks...serum estradiol and inhibin B (testosterone) levels were observed in men only.”


“In an evaluation of CDC-collected exposure data for American children, researchers found that adolescent boys with higher oxybenzone measurements had significantly lower total testosterone levels (Scinicariello 2016).”


“Since then, studies have shown a potential link between oxybenzone and lower testosterone levels in adolescent boys, hormone changes in men…”


“When adults applied a sunscreen formulation containing 10% (Oxybenzone) (Enzacamene) and (octinoxate) on a daily basis for a week, the mean urine concentrations for these was higher in men.”


“In one epidemiological study, 2517 urine samples from United States (US) general population were analyzed for the presence of oxybenzone as part of the National Health and Nutrition Examination Survey, BP-3 (aka Oxybenzone) was detected in 97% of the samples…”



Both women and men have these chemicals in them for over 24 hours after use. Per the study, the men held onto as much as double the amount of the chemicals tested compared to the females. 

“In the present human study, we have demonstrated for the first time that the sunscreen compounds BP-3 (benzophenone), OMC (oxtinoxate), and 4-MBC (Enzacamene)  were  absorbed  through  the  skin  and  excreted  in urine.”



“Homosalate is a potential endocrine disruptor and studies in cells suggest it may impact hormones. In addition to direct health concerns following homosalate exposure, the chemical may also enhance the absorption of pesticides in the body.”,skin%20care%20products%20with%20SPF.&text=Salicylates%20prevent%20direct%20skin%20exposure,increased%20risk%20of%20skin%20cancer.




Good (facts) Bad (facts) Unknown 

all 6 of the tested active ingredients administered in 4 different sunscreen formulations were systemically absorbed and had plasma concentrations that surpassed the FDA threshold for potentially waiving some of the additional safety studies for sunscreens. 

over a 21-day period, the researchers discovered that after the initial sunscreen application, the concentration of the six chemicals increased within the bloodstream each day it was applied, and stayed above FDA-mandated safety levels at day seven—which was after the study participants had stopped applying it. Not only that, levels of the ingredients homosalate and oxybenzone were still above safety thresholds on day 21.

The findings support those from a pilot study conducted by the FDA last year, which also found that four popular chemical sunscreen ingredients (avobenzone, oxybenzone, octocrylene, and ecamsule) were easily absorbed into the skin and went into the bloodstream after one day of use.

Good Ingredients in Ginger Armor:


Zinc Oxide (Non-Nano to keep the user and nature safe) is a mineral sunscreen and the only FDA approved sunscreen ingredient to cover both UVA & UVB sun rays.

Zinc oxide is a safe and effective ingredient in photoprotective products. It is photostable, nonphotoreactive,[19

(Moloney FJ, Collins S, Murphy GM

Am J Clin Dermatol. 2002; 3(3):185-91.

Zinc oxide is nonphotocatalytic.[12] It has little potential for irritation or sensitization.

(Nash JF Dermatol Clin. 2006 Jan; 24(1):35-51.)

Titanium Dioxide is a mineral sunscreen covering UVB and partial UVA sun rays.

Titanium Dioxide 7.8%, Zinc Oxide (Non-Nano) 9.0%

“Titanium dioxide is a broad-spectrum UV filter that does not penetrate the stratum corneum.” (Reena Rai, Sekar C Shanmuga, and CR Srinivas 2012)


Squalane mimics your skin's own moisture and keeps our skin's outer layer moisturized and protected. Our sebaceous glands naturally produce it and production declines in our 20s and 30s. Protects against damage from free radicals. Softens, hydrates and locks in moisture.

Origin: Our squalane is sourced from sugarcane*


Argania Spinsosa (Argan) Oil nourishes, protects elasticity and reduces the appearance of fine lines and wrinkles.It’s benefits include: anti-aging, anti-inflammatory, antioxidative, moisturizing and anti-viral benefits. 

Origin:  Kernels of seed of Argania Spinosa plant.


Vitis Vinifera (Grape) Seed Oil is an exceptionally strong moisturizer and antioxidant. Helps tighten the skin. High in linoleic and other fatty acids and helps with acne. 

Origin: seeds of grapes from the plant Vitis vinifera


Helianthus Annuus (Sunflower) Seed Oil traps moisture and keeps skin well hydrated. It also helps prevent damage to cells by ultraviolet light and aids against premature aging of skin by protecting the collagen and elastin content.

Origin: seeds from sunflower

Carthamus Tinctorius (Safflower) Seed Oil has “high antioxidant effects and antimicrobial potentialities against several opportunistic skin pathogens. It seemed to act by bacteriostatic and bactericidal pathways as well as a strong antifungal growth inhibition.” (Oxid Med Cell Longev. 2020)

Olea Europaea (Olive) Oil has antioxidant and anti-inflammatory effects and is free radical fighting. Olive oil can penetrate the skin, prevent loss of moisture and give a silky smooth softness.

Origin: olives, fruit of olea europaea


Carthamus Tinctorius (Safflower) Seed Oil is a lubricant for the skin surface, which gives the skin a smooth appearance. It is also used as a skin conditioning agent and is high in linoleic acid (aka omega 6 fatty acid) It is recommended for acne and is also good for reversing UV-induced hyperpigmentation (aka sun spots) in lab tests. One of Traditional Chinese Medicines' fundamental ingredients. 

Origin: seeds of the Safflower plant


Anti-Inflammatories Anit-oxidants

Rosmarinus Officinalis (Rosemary) Extract relieves skin inflammation and can soothe acne, eczema, and psoriasis. Rosemary Antioxidant protects cells against not only oxidation and inflammation but also against pathogens

Origin: ground dried rosemary leaves


Bisabolol soothes inflammation. Having proven anti-inflammatory properties, bisabolol helps with acne, rashes, rosacea, psoriasis, and similar conditions associated with frequent skin irritations. It has also been shown that bisabolol calms the skin after exposure to UV rays, and tones down sunburns and redness.

Origin: Chamomile plant & bark of the Candeia tree of Brazil


Oryza Sativa (Rice) Bran Extract absorbs UV light, is rich in essential fatty acids, and has antioxidant properties. Egyptians were known to use it to prevent their skin from tanning. 

It’s also been proven to be an anti inflammatory. 

Origin: outer layer of the rice plant known as the bran


Tocopheryl Acetate (Vitamin E) has antioxidant and anti-inflammatory properties and is most commonly known for its benefits for skin health and appearance. It can be applied topically to your face to reduce inflammation and make your skin look younger.

Tocopherol (Vitamin E)

Antioxidants that are used in sunscreens and cosmetic products are vitamins and polyphenols. Vitamins formulated in sunscreens are water soluble vitamin C and lipophilic vitamin E. Application of L-ascorbic acid has shown to protect UV-related damage as measured by erythema or sun burn cells.[24

Inhibition of ultraviolet light-induced erythema by antioxidants.

Roshchupkin DI, Pistsov MY, Potapenko AY

Arch Dermatol Res. 1979 Aug; 266(1):91-4.

Topical application of α-tocopherol has demonstrated a number of protective effects including reduction in erythema,[25] photoaging,[26] photocarcinogenesis,[26] and immunosuppression.[27]

Pongamia Glabra Seed (Karanja) Oil has antioxidant and emollient properties and is anti-inflammatory

Origin: Seed of Pongamia tree



Stearic Acid has been shown to protect skin's surface against water loss and help shore up skin's protective barrier.

Coconut Alkanes is a volatile (something that does not absorb into the skin but evaporates from it), naturally derived vegetable alkane coming from renewable sources. It is a light, oily liquid that works as an emollient and gives a smooth skin feel.

Coco Caprylate/Caprate is a vegetable ingredient obtained from coconut. It presents a high level of biocompatibility with skin and therefore has the ability to penetrate deep and help skin to repair itself. It acts as an emollient and provides skin with incredible softness.

Caprylic/Capric Triglyceride creates a barrier on the skin's surface, which helps to reduce skin dryness by decreasing the loss of moisture.

Aids in making the sunscreen clear and lightweight

Alumina is an anti-caking agent: absorbing excess moisture by coating particles and making them water-repellent. It holds onto oils so they don't look shiny.

Polyhydroxystearic Acid is a commonly used dispersant for ultrafine titanium dioxide and zinc oxide. It renders the zinc oxide particles extremely hydrophobic and lipophilic, so that they are easily dispersed in esters, mineral oils and silicone fluids.




Video: dermatologists vary in what they consider comedogenic. Proof tests aren’t done in real life conditions. The most common test is the rabbit ear model, they apply the substance to the inside of a rabbits ear (because it’s much more sensitive than human skin) there were tons of false positives with this.


Nanomaterials are ultrafine single particles with a diameter less than 100 nm. (these can enter your bloodstream)

(Maynard A. Nanotechnology: A research strategy for addressing risk. Woodrow Wilson International Center for Scholars. 2006. Jun, [Last accessed 2007 Dec 1])

The adverse effects of nanoparticles include interface for catalytic reactions, complexes with proteins which can escape immunological surveillance, induction of autoimmune diseases

(Donaldson K, Stone V, Tran CL, Kreyling W, Borm PJ. Nanotoxicology. Occup Environ Med. 2004;61:727–8. )

Ginger Armor is ultra fine to keep it from being pasty, thick or white in appearance, but still 280 nm so it doesn’t risk ending up in your bloodstream (100nm or less is considered a nano particle)


Oxybenzone is not photostable and can generate oxygen radicals upon UV exposure.(Schallreuter KU, Wood JM, Farwell DW, Moore J, Edwards HG J Invest Dermatol. 1996 Mar; 106(3):583-6.)

There is a concern about its endocrine and carcinogenic effect even though current scientific studies have not supported this fears.

(Janjua NR, Mogensen B, Andersson AM, Petersen JH, Henriksen M, Skakkebaek NE, Wulf HC

J Invest Dermatol. 2004 Jul; 123(1):57-61.)



Butyl methoxydibenzoylmethane or avobenzone provides superior protection through a large portion of the UVA range, including UVA I. Despite its efficacy and broad spectrum, avobenzone is intrinsically photounstable and significant photodegradation can occur with a loss of 50–90% of molecules after 1 hour of UV exposure.

(Photostability assessment of sunscreens. Benzylidene camphor and dibenzoylmethane derivatives. Deflandre A, Lang GInt J Cosmet Sci. 1988 Apr; 10(2):53-62.)

10/10 for this spf for sensitive skin!

I am extremely particular about the ingredients in my skincare. I don’t have words to tell you how excited I was to purchase this eco-conscious brand!! I LOVE that it’s plant-based and that it packs argon oil and squalene in with spf 50 😎 Thank you creating a 2-in-1 moisturizer that doesn’t smell or leave a weird white film on my face! I’m. So. Grateful!! 👩🏻‍🦰

wow thank you for the 10/10 rating Ashley! I'm also extremely particular about the ingredients in my skincare and really appreciate your review-the ingredients I chose to use are intentional and I'm really proud that they are good for you and eco-conscious-this was not easy to do while also keeping it not smelly, or leaving a white film on your face. I really appreciate you noticing and saying so. Thank you for your support Ashley!

Gives my skin a dewy fresh look!

I can't say enough great things about Ginger Armor! Love how it glides on my skin and leaves it moisturized and protected! If you're on the fence about it - don't be, get some!!!


I am blown away by the quality and design of this product. I have been using now for a couple of weeks as a daily moisturiser and my skin feels softer, looks clearer and I know I don’t have to worry about sun damage throughout my day. The size of packaging is super convenient - allowing you to take in cabin bags for short-haul destinations. I have a fully booked Summer of holidays and I just know Ginger Armor is going to be by my side for every single one ✌🏼

Thank you so much for your review Bladon! It means a lot to me! I'm honored that you take ginger armor with you on your travels and really appreciate you sending these great photos and video to show everyone that you love ginger armor!

Thank you for your review,

Never switching sunscreens again

Ginger Armor is my favorite skincare product. That sentence ends in a period. It means period, and implies no further explanation needed, but since you insist I’ll tell you why!

Ginger Armor is the most thoughtfully formulated sunscreen on the market. It’s lightweight, doesn’t leave any white marks or oily residues on my face, and probably best of all has allowed me to replace certain steps in my skincare routine! I used to take a couple of drops of Argan oil and vitamin E and spread them on my face. Thanks to GA I no longer waste my time doing extra steps or buying extra product (more space in my bathroom!).

I also appreciate that it’s housed in aluminum. More recycling centers are equipped to process aluminum than the plastic bottles most other sunscreens come in. This also allows me to keep a bottle in my car without worrying about the container melting or leaching plastic chemicals into my sunscreen (and then onto my face!). I use it before I leave the house, but keep one in my car to reapply when surfing or hiking, especially for friends who forget to apply.

I also love that it doesn’t contain a fragrance! It has a pleasant nutty scent that dissipates once applied, so it never clashes with my cologne.

Take it from someone who is probably too proud of the fact that most people think he’s still in his twenties because of his skin: Ginger Armor is the be-all end-all of sunscreens, and deservedly so.

Thank you for your review Ashe! I am so grateful that you love Ginger Armor and appreciate you spreading the word about why you do!


This product is amazing! Truly a great moisturizer and powerful sunscreen in one. And the best part!? It really does rub in clear no white marks or patches. Will definitely be making this apart of my daily routine :)

I'm so happy you like it and are making it apart of your daily routine Scott!

I really liked that this left no white cast and feels like moisturizer. I'm pleased to use a sunscreen that is environmentally friendly. I did notice a slight odor--it doesn't bother me and doesn't smell like a typical sunscreen. Rather, I think I'm smelling the mineral.

Best sunscreen out there!! If you’ve done your research you know that mineral sunscreen is the only way and this one has been perfected. No nano zinc and no white residue. So actually safe to put on your kids and no complaining about white marks! Truly the only sunscreen you should consider buying!!

The texture of Ginger Armor is amazing! Goes on super smoothly and disappears right away. It slows down my freckle collection like a dream and leaves my skin feeling great! Not greasy or chalky-looking. This sunscreen is MUCH better than I expected and the packaging is brilliant. Practical and clean. I plan to be a customer for life!

As good as advertised

Most sunscreens give me contact dermatitis, so I’m always looking for one that my skin can tolerate, in addition to being reef safe, biodegradable, mineral-based, not over-scented, and blends well into my pale skin. This is the one! I’m very pleased with the results and am thrilled. The price is comparable to big name brands and performs better. And the packaging isn’t plastic! I highly recommend Ginger Armor, especially if you have sensitive skin.

Great all in one

I've been looking for a combo product for a while. I need extra sun protection but also a moisturizer bc let's face it, I'm not getting younger lol. This product provides both of these. I am also highly sensitive to anything on my face and this product works great on my sensitive skin. I don't have any flare ups or redness! Love it

Shockingly great!

Do I have a collection of sunscreens at home most of whom have betrayed me in some way? Oh yeah! Was I skeptical that this would somehow be different. Yup. Was I pleasantly surprised to be proven wrong? No, I was outright shocked! This stuff is amazing!! I’m a flight paramedic and often get caught outside in the sun for an extended time on occasion. Ginger Armor is quick and easy to put on. It doesn’t run or sting your eyes when you sweat. Doesn’t feel gross. Multiple subsequent applications even feel like they’re barely there but still provide great coverage. I’m literally throwing all my other sunscreens away. My ONLY complaint is that I’ve noticed a little leaking / pooling around the pump, but it’s not excessive and I can usually just wipe it up with my finger and put it somewhere on my face for extra protection. Getting my second bottle so I don’t run out!

Amazing stuff

Seriously love this stuff. Ginger airline pilot from TX. And I wear this religiously. Only bad is it says only two hours of direct sunlight? Most of the mineral stuff I use says 4 hours.

Great Sunscreen

I’ve used a lot of sunscreen working outside as a horse trainer. I’ve always liked mineral sunscreens for lasting longer and being more effective than chemical, plus like not having it in my bloodstream… but I have always hated the feeling of “painting it on” because of how thick mineral based sunscreens can be. Or how they made me look like a ghost. I was thrilled to see how light and sheer Ginger armor really is. It’s pleasant to put on and I can use it anytime, not just when I don’t care about my looks. I also loved the eco-friendly packaging. Very impressed!

A new fav thing

This is a huge suprise. Excellent at both moisture and sunscreen. I have used it daily and am beyond impressed. The spray bottle could use a bit of work, but that is a tiny complaint.

They fit & work great !!!

They don’t look bad either. Unbelievably lightweight.

Thank you for your review Tris! I'm so happy that you like them!

Customer service

There was an minor issue with my delivery. Skyler promptly responded to my email and resolved the issue immediately. It's the first time I have had customer service so honest and reliable what a pleasure in today's busy world where nobody takes the time to communicate. Thank you Skyler

You're welcome Carlene! Thank you for letting me know and I'm so happy we got everything resolved!

Not good

Leave a white cast 👎

Hello Bindia, did you make sure to use Ginger Armor after you dried off? If you apply it to dry skin it will rub in clear within 1 minute. Would you please be sure to check out our 'how to use' video and/or reach out to me at if you have any questions or want any 1/1 tips? Thanks!

Great sunscreen!

It's moisturizing and watery and I love it!

Thank you so much Joy! I'm glad you love it! :)

The Greatest!

We both have very fair and sensitive skin so Ginger Armor is a God-send for us. We have tried for years to find a sunscreen that did not contain chemicals and would protect us without costing us our life savings. You have given us that in Ginger Armor and more. The dry feel and moisturizing effects on my face and all my limbs is the greatest! As Arizona is very dry most of the year, I see us using Ginger 12 months of the year. Thanks for inventing something for us, the ghost white, burn and peel people who love the sun,but up until now have avoided the sun. Thank you for sharing with all us almost gingers who need protection too, and thanks to David Pakman for telling us about Ginger Armour!

Ellen-I'm so happy that Ginger Armor is keeping you safe and moisturized in Arizona and am honored that you're using it year round! It makes me so happy that you're getting outside and using Ginger Armor. I like the term you made up 'Almost Gingers' and agree, everyone needs protection-Ginger or not. Thank you David Pakman for telling people about Ginger Armor!


This is the best sunscreen I’ve used!
The scent of the almond oil is fairly strong and not my personal favorite, otherwise this sunscreen is practically perfect and great for sensitive skin!

I'm really happy that this works great for your sensitive skin!

This is a great product!

I keep some in my car so I can open the sunroof and not burn; I keep some in my purse in case I spend extended time in the sun; I combine it with my moisturizer, adding fantastic SPF to my daily routine. It is lightweight and absorbs quickly. I love that there isn't any residue and it has no odor.

Very smart to keep some in your car-I leave a bottle in my bathroom, car, gym bag, and hiking/camping gear so that I'm always ready. So happy to hear that you love how it absorbs quickly and doesn't have any residue or odor-this makes it so you'll actually wear it right?
Thank you so much for your review!

Love it

It has nice subtle scent and goes on smooth and evenly. Love it for every day use.

Thank you for your review Crystal! I'm honored you used it every day!

Easy to apply, non-drying, non-irritating

I am enjoying the Ginger Armor moisturizer & sunscreen. I like that the ingredients are safe and do not aggravate my sensitive, acne-prone skin. As a liquid, it is very easy to apply to the face and neck, and it does not dry out my skin (which is a problem I've experienced with nearly all the mineral sunscreens I've tried). The only trouble with it is that it leaves your skin quite visibly shiny for 1-2 hours before sinking in. It is also not very easy to get the white cast to disappear, although it does go away (almost entirely) if you rub it, wait, and rub some more. Overall, I am quite pleased. It would be great if the company produced a tinted version!

Thank you for your review Brook! I'm so happy to hear that Ginger Armor doesn't aggravate your sensitive, acne-prone skin. Thank you for appreciating that it's liquid and that makes it so easy to apply (this is one of my favorite parts about it) It's also moisturizing like you said and I experienced the same issue with mineral sunscreens. To reduce any shine I've found that drying my face off completely really helps reduce the shine/glow. Also, we are working on a tinted version! I'm glad you mentioned that and genuinely appreciate your feedback and review. Thank you!
