This study (by the National Toxicology Program) has been attacked from all quarters, including the unsuitability of the subject matter: hairless mice. The concern is that topical applications of creams containing RP followed by UVR exposure can increase the risk of cancer. There is a raging debate about the risk vs. RP is a Vitamin A compound, that has does not show significant anti-aging activity. ![]() ![]() Clockwise from top left corner: Ultra Sheer® Dry-Touch Sunscreen Broad Spectrum SPF 30, 45, 55, 70, 85+, 100+ AND Clear Face Break-Out Free Liquid Lotion Sunscreen Broad Spectrum SPF 30, SPF 55 Clockwise from top left corner: sunscreen sticks (Beach Defense SPF 50+, CoolDry Sport SPF 50+, Ultra Sheer SPF 70), Sport Face Oil Free lotion SPF 70+, Oil Free moisturiser SPF 35, Healthy Defense Moisturiser SPF 50, Ultra Sheer Liquid SPF 70, Wet Skin kids stick SPF 70+, age shield face SPF 70, Age Shield oil-free SPF 110 D) Nine products also contain Retinyl Palmitate The MI culprits are: Clockwise from top left corner (Sensitive Skin Sunscreen Lotion SPF 60+, Age Shield SPF 70, Age Shield Face Oil-Free SPF 110, Oil Free moisturiser SPF 35, Ultra Sheer Dry Touch SPF 100, 70, 85+, Sport Face Oil-Free Lotion SPF 70+, Healthy Defense Daily Moisturiser SPF 35 C) Eighteen sunscreens contain BHTīHA and BHT can induce allergic reactions in the skin and some evidence, suggests that high doses of BHT may mimic estrogen resulting in adverse reproductive affects. It’s also been named Allergen of the Year by the American Contact Dermatitis Society. In the US, MI is a preservative that is allowed in sunscreens, but this is under review. MI is a preservative that the EU does not permit in leave on products such as sunscreens because its a contact allergen (see Note 1 below). The paraben culprits are: Clockwise from top left corner (Sport Face Oil-Free SPF 70+, Ultra Sheer Dry Touch SPF 55, Oil-free moisturiser SPF 35, Healthy Defense daily moisturiser SPF 50, Ultra Sheer Dry Touch SPF 45 B) Eight sunscreens contain Methylisothiazolinone ( “MI”) Neutrogena gets that consumers don’t want this obnoxious preservative in their product, as the other 34 products don’t have parabens. (See “ Chemicals to avoid – parabens” for more details). Parabens are hormonal disruptors that act as estrogen mimickers. The Undesirable Group A) Five sunscreens contain Parabens Its this other group of similarly undesirable chemicals that find their way into many Neutrogena sunscreens. BUT I wouldn’t have written this post if it was JUST Oxybenzone that was the problem. Thirty four out of the 39 sunscreens I analysed, contained Oxybenzone (see Chemicals to Avoid – Benzophenone 3 for more details). What’s my beef with Neutrogena sunscreens? (For more details, please read “ How to pay the lowest price for your sunscreen,” where I highlight the ubiquity of 21.6% Zinc Oxide formulas). Most of these sunscreens, are Zinc Oxide 21.6% formulas. Sunscreens featured are: Zinc Oxide 21.6% group (SheerZinc Face Dry touch sunscreen SPF 50, SheerZinc Dry touch sunscreen SPF 50, pure & free baby sunscreen SPF 50 (liquid and Zinc Oxide formula) and Neutrogena Hydro Boost Water Gel Lotion SPF 30 Without any doubt, Neutrogena sunscreens with SPF 30 and above, provide broadspectrum coverage and the presence of Avobenzone, ensures that this includes UVA1 protection.ĭespite the above, out of the 39 sunscreens I found (in yes a CVS pharmacy), I’d only be comfortable with 3-4 products. The Avobenzone is stabilised by Octocrylene, high amounts of Oxybenzone and most likely, other (for want of a better word) photostabilisers. ![]() A UVA filter (Avobenzone – the only UVA1 filter permitted in the US) and.UVB filters (Homosalate, Octinoxate, Octocrylene) with.Helioplex is synonymous with Neutrogena and my understanding is that it combines: Neutrogena in their “Helioplex” formulation have chosen the Avobenzone route. In the US there are severe limitations on sunscreen manufacturers and in order to provide UVA protection they can either choose between Zinc Oxide OR Avobenzone.
