Best sunblock review: Keys Solar Rx

Keys Solar SunblockWoot!  I’ve finally got my hands on Keys Solar Rx  SPF30+, the safest and most effective  broad spectrum UVA and UVB 100% vegan sunblock with the ability to protect my face from UV radiation while using no harmful man-made chemicals, fragrances or preservatives.  

And I honestly think that paying US$19.95 for the 100ml broad-spectrum sunscreen with 16 percent uncoated nano-zinc oxide is quite a steal.  I mean that price for a sunblock featured on the Environmental Working Group Skin Deep Report as the safest, as well as rated the most effective non-waterproof sunblock for UVA and UVB in the Consumer Reports July issue?  You may also like to know that zinc oxide is the best sunscreen ingredient according to this rating compiled by Environmental Protection Agency.


Like what I wrote earlier, what’s great about Keys Solar Rx SPF 30+ Sunblock is that it is transparent on the skin when applied because of the cosmetically clear transparent nano-zinc oxide and hence, can be worn under moisturizer and makeup beautifully without leaving any white cast.

But I realized that the all-natural formula which includes over 84% organic contents like avocado, black cumin, carrot seed oil, and shea butter is rather emollient.  Thus, I only need a tiny bit of it or my face will feel too greasy and my makeup will become streaky.   The sunblock also has a rather sharp scent which needs getting used to. 

Still, I’m happy with my synthetic-chemical-free Keys Solar Rx SPF30+ Sunblock because the low health hazard product with high UV protection gives me total peace of mind!  Completely! 

Keys Soap Solar RX Therapeutic Sunblock, SPF 30 is also available at Amazon.

    hey babe, thanks for putting up places to buy mineral make-up. (=

    hmm how did you purchase the solar rx the other time? i just tried the website and it claims tt there are no shipping options for my address (singapore!)

    and how long did it take you when you bought it? thx!

    chenyze: You’re welcome! About Solar RX, I bought it direct from – use the link here. I just checked and they still have shipping to Singapore. I used vPOST the last time though cos I found the shipping rates expensive plus I had other items coming from other online shops.

    I would embrace this product as well, except for the fact that nanoparticles have not been well studied and we don’t really know what effect they may be having on us if they are entering the body through the derma, and if this is a problem… I wish there was more literature available but I don’t think there has been much clinical testing. This would be a great column for you to write if you do a bit of research.

    Kate: Yup, I know where you’re coming from. For me, I think I’ve gone over that mental threshold and hence, I am using it. Well, I will cover something about the technology if I can find anything substantial in future.

    A quote from “Sunscreen Photobiology—Molecular, Cellular and Physiological Aspects”

    “Illumination of titanium dioxide suspensions with sunlight can degrade organic materials and purify drinking water, while illumination with short wave UV kills human cells. This work shows that the distinction between ‘chemical’ sunscreens and ‘physical’ sunscreens, attractive though it may be to those who market them, is not based on any significant difference. Both varieties have the potential to produce reactive species that can attack biological materials (human skin cells) when they are exposed to normal sunlight… What is established is that particles of titanium dioxide as large as 220 nm can enter human cells in culture, and so it seems entirely plausible that if titanium dioxide does pass through skin it could enter cells under the skin (carrying with it the absorbed UVA and UVB radiation and hydroxyl radicals).”
    “The shocking truth is the fact that both chemical sunscreens (avobenzone, methoxycinnamate, padimate-o and the like) and physical sunblocks (titanium dioxide and zinc oxide) have been found to generate free radicals when exposed to sunlight, which then can attack the nuclei of your skin cells and cause mutations.”

  6. kareny says:

    Quote from Leslie Baumann book Cosmetic Dermatology:

    “One problem however with physical sunscreens is that they may produce oxygen free radicals at their surface when irridiated. The photoreactivity of metal oxides has been extensively studied, and it even has been suggested that photoactive metal oxides may initiate deleterious events in the skin.”
    “TiO2 even damages DNA in invitro studies”
    “Most companies minimize the photoreactivity of these agents by coating the surface with dimethicone or silicone.”

    kareny: Thanks for your informative quotes. These are certainly something to consider but you may also like to know that even bare skin will generate free radicals when exposed to UV radiation. My understanding is zinc oxide and titanium dioxide do not penetrate the stratum corneum so easily. In addition, it might help to look out for formulations of physical sunscreens that are fortified with antioxidants to help reduce the potential radical damage.

    As a whole, I still prefer physical sunscreens over chemical sunscreens. Even my dermatologist recommended the former. I also like to add that, ingredients and types of sunscreen has been widely debated but most probably, no one has a clear cut answer to what is the safest and most effective sun protection.

    I bought this product after reading positive reviews online. After using it for a couple months, the pump failed and I was not able to extract the remaining ~80% of sunscreen. The company never replied to my subsequent emails. Caveat emptor.

    N8: Oh, what a shame! I would be so annoyed too! Anyway you can ply open the can?

    I find your blog incredibly helpful.
    My wife is very fair and most sunscreens do little for her time out in the sun. Also, since we live in Southern California and she has just hit 30, we are both concerned about photo-aging.

    I like the Zinc products. Is Keys product enough for a very fair-skinned person? Is there a higher SPF out there? Also what about something that is water-insoluble for those beach trips.


    Ed: Hi! Welcome and I’m so glad you find the info here useful.

    Keys Solar Rx is good for daily use as the zinc oxide content is rather high. The SPF does not matter that much because the difference between SPF 50 & SPF 30 is minimal. You can read my article here for a better understanding of that if you like. What is needed is actually frequent re-application for it to be effective.

    However, Keys Solar Rx is not something I would recommend for water sports. For that, go for something that is water resistant. If you want something with zinc oxide, then Badger SPF30 might be good as it is said to be water resistant for up to 40 mins. I’ve tried that product and found the formulation too oily but I think it might good for water sports though. I myself am using a chemical based one from La Roche-Posay Anthelios XL 50+ for water sports usage.

    I also heard the Blue Lizard range from Australia is good. I haven’t had a chance to try them but you might want to check it up where you are.
