Barry M Cosmetics All In One Nail Paint

Reported use concentrations run from 0.002%-100% and any number over 50% usually comes from a nail product.

Actual skincare numbers run much lower: cleansers (0.3-26%), toners (0.07-7%), face moisturizers (0.04-0.2%).

The Cosmetic Ingredient Review Expert Panel reviewed it and concluded it is safe in the present practices of use and the International Agency for Research on Cancer classifies it as a non-carcinogenic to humans.

True allergy to this ingredient is uncommon but real: 44 out of 1,450 patients patch tested between 1992-2011 reacted with most cases clustering in people with leg ulcers, occupational hand eczema, or repeated use of Isopropyl Alcohol on already-broken skin.

Irritation and dryness are far more likely than allergy; before you throw away your skincare, just know this is dose-dependent and the risk is modest.

The irritant potential of the alcohols used in hand antiseptics is very low and skin irritation is significantly lower after alcohol application than after detergents (though isopropanol is somewhat more irritating than ethanol).

A 70% solution was a severe eye irritant in rabbit eye tests so the industry keeps this ingredient at low percentages in eye-area products.

One genuine caution: a 70% solution was a severe eye irritant in rabbit eye tests, so it belongs at low percentages in eye-area products, which is where the industry already keeps it.

According to the National Rosacea Society based in the US, you should be mindful of products with these alcohols in the top half of ingredients.

On concentrations:

So why did the EU cut back on how much you can use?

It comes down to absorption. Oxybenzone passes through skin more easily than other filters.

When the FDA tested sunscreens, every filter showed up in people's blood above the level where the agency wants extra safety testing done. But Oxybenzone showed up at by far the highest levels of the bunch.

To be clear, the FDA's point was that we need more research and not that the ingredient is dangerous. They also said to keep using sunscreen.

That high absorption, plus some animal studies pointing to effects on reproduction, is why EU regulators labeled Benzophenone-3 a hormone disruptor in 2025. An official classification is expected to follow in 2026.

It's also the most common photoallergen among sunscreen filters so it's a more frequent cause of contact/photoallergic dermatitis than most alternatives.

Places like Hawaii and Palau have also banned it over coral-reef concerns.
