Sunlight can be a friend — or foe — for those living with psoriasis. Make sure you choose the right sunblock for your sensitive skin.
For many people, warm weather means outdoor activities like swimming and backyard barbecues.
Proper sun protection during outdoor activities is important for everyone. But people with psoriasis need to be particularly careful.
If you have psoriasis, you may have heard that exposure to ultraviolet B (UVB) rays has actually been shown to help with the autoimmune skin condition.
“UVB rays are actually good for people with psoriasis,” says Jacqueline Schaffer, MD, founder of Schique Skincare. UVB rays help slow the skin growth and shedding that happens with psoriasis.
But too much sun exposure — of both UVA and UVB rays — can be a problem. “If people with psoriasis are overexposed, it can actually worsen the skin,” Schaffer says. “They’re extra sensitive versus someone who doesn’t have psoriasis.”
Psoriasis also mostly affects people with lighter skin tones who are already more prone to sunburn.
Plus, certain medications used to treat psoriasis can cause increased photosensitivity. This makes a person sunburn more easily.
For all these reasons, wearing sunblock when you have psoriasis is crucial. It’s important to choose wisely since skin may already be irritated and sensitive.
Make sure there are no parabens, no formaldehyde, and no other really strong preservatives.

Follow these expert tips next time you’re shopping for sunblock.
1. Make sure you’re buying sunblock, not sunscreen
“Sunscreen is known to be absorbed into your skin, whereas sunblock actually sits on top of your skin and reflects the UV rays,” Schaffer says.
Many products are a mixture of both, so a product labeled “sunscreen” can still have enough protection if it also contains sunblock. Common sunblock ingredients include zinc oxide and titanium dioxide.
2. Avoid preservatives and chemicals
“Make sure there are no parabens, no formaldehyde, and no other really strong preservatives that can be damaging to the skin,” Schaffer says. These ingredients can irritate psoriasis patches.
3. If you’re shopping for a child, don’t buy sunblock with added color
Some companies now offer colored or “disappearing color” sunblocks. Parents should avoid buying these for children with psoriasis, Schaffer says, as they can irritate skin.
4. Don’t buy sunblocks with added scents
Added fragrances can aggravate the skin in people with psoriasis.
5. Buy SPF 30 or above
People with psoriasis need just as much sun protection as everybody else. This is especially true if they’re on medications that can increase their sensitivity to the sun.
SPF 15 doesn’t provide enough protection throughout the day. “A lot of studies from the American Academy of Dermatology have shown that SPF 30 is more effective for longer use as a sunblock,” Schaffer notes.
6. Look for the label “broad-spectrum”
This meansthe product will protect against both UVA and UVB rays. Even though UVB rays can be beneficial in treating psoriasis, people with the condition should still have sunblock on to protect against too much exposure to both types of rays.
If you have psoriasis, try one of the following products that made it through the above checklist and past the experts.
This water-resistant product is free of dyes, fragrances, and chemicals, and is another of Schaffer’s go-to recommendations.
Cost: Starting at $34
Title: Takeaway People
with psoriasis should wear sunblock in the sun, even when using the sun as
treatment for their condition. Look for broad-spectrum, fragrance- and
preservative-free sunblocks that are at least SPF 30.
If you have psoriasis and are planning on being in the sun, experts recommend starting with 10 minutes of exposure at noon, then increasing exposure by 30 seconds to one minute each day.
