š« Harmful Sunscreen Ingredients to Watch Out For
1. Oxybenzone
One of the most widely used chemical UV filters, oxybenzone has been detected in human blood, urine, and breast milk. Studies suggest it may act as an endocrine disruptor, interfering with hormone function. It's also been linked to coral reef damage and is banned in several ocean-conscious destinations like Hawaii.
2. Octinoxate (Octyl Methoxycinnamate)
Another common chemical filter, octinoxate has shown potential hormone-disrupting effects in animal studies. Like oxybenzone, it's been found to penetrate the skin and enter the bloodstream, and it's harmful to marine ecosystems.
3. Homosalate
Found in many popular drugstore sunscreens, homosalate helps other chemicals penetrate the skin ā including itself. The European Commission has flagged it as a potential endocrine disruptor and recommends limiting its concentration in products.
4. Octisalate & Octocrylene
These chemical filters are often used together to stabilize other UV-absorbing ingredients. Octocrylene in particular has been shown to accumulate in the body and may degrade into benzophenone, a potential carcinogen.
5. Retinyl Palmitate (Vitamin A)
While it sounds skin-friendly, this form of Vitamin A is a concern when used in sunscreen specifically. When exposed to UV light, it may speed up the development of skin lesions and tumors, according to some animal studies by the National Toxicology Program.
6. Parabens (Methylparaben, Propylparaben)
Used as preservatives, parabens mimic estrogen in the body and have been found in breast tumor tissue. While research is ongoing, many health-conscious consumers choose to avoid them entirely.
7. Fragrance / Parfum
This catch-all term can hide dozens of undisclosed chemicals, many of which are allergens or irritants. Fragrance is one of the leading causes of contact dermatitis and skin sensitivity reactions.
ā 5 Cleaner Sunscreen Options to Try
These mineral-based sunscreens use zinc oxide and/or titanium dioxide ā physical blockers that sit on top of the skin rather than absorbing into it ā and are free from the harmful chemicals listed above.
