ChemicalsĬohen also suggests avoiding any sunscreens that use chemical products to block the sun, “as chemical sunscreens can be irritating,” he explains. “Many sunscreens have fragrances in them, so it is important to look out for this and choose products without any fragrances,” he says. Why? Many people have an inflammatory reaction to fragrance. This goes for natural fragrances, including essential oils. ![]() The NEA explains that fragrance is a relatively common allergen that can be irritating for anyone with sensitive skin. If you have eczema, try to avoid fragrance, Cohen says. There are specific ingredients known to cause flare-ups, which the NEA details on its website. More important than what to look for in a sunscreen - or any cosmetic product, for that matter - is what to avoid. If you’re living with atopic dermatitis, reading ingredient labels is absolutely crucial.

While it isn’t exactly clear how sunlight improves eczema, there is some scientific evidence, described in an article in the May 2015 Journal of Clinical Medicine, that vitamin D may improve the skin condition by regulating influence on both the immune system and skin barrier function. “Phototherapy, a commonly used treatment for eczema, involves exposure to certain safe wavelengths of light that are emitted by the sun,” Cohen says. Phototherapy or light therapy is used for this very purpose.

A study published in December 2019 in the Journal of the Mechanical Behavior of Biomedical Materials found that UV light weakens the bonds between cells in the stratum corneum, the top layer of skin, by damaging the proteins that help skin cells adhere together. While the sunscreen itself doesn’t directly strengthen the skin barrier, it will protect your skin from the sun. Regularly using sunscreen can help prevent this from occurring,” says Jeffrey Cohen, MD, a board-certified dermatologist and an assistant professor of dermatology at Yale University in New Haven, Connecticut. “Sunburns compromise the skin barrier, which is already compromised in people with eczema, and can lead to flares. After all, excessive sun exposure can lead to sunburn in anyone, including people with atopic dermatitis. Your quest to find an eczema-friendly sunscreen is worthwhile.
