Can Sunlight Clear My Psoriasis Flare-Up?

Researchers have long known that exposure to sunlight can lead to a reduction in psoriasis flares. You may have heard about this connection from other friends with psoriasis or read about it. But what you may not know is whether sunlight can clear up an active flare. And if it can, how much sunlight does it take—and is the sun really your best option?

Can Sunlight Clear Up a Psoriasis Flare?

The simple answer to this question is yes, according to board-certified dermatologist Rhonda Klein, M.D., of Modern Dermatology of Connecticut in Westport. “The sun has been shown to improve or slow down a psoriasis breakout,” says Klein. “Specifically, the UVB rays can slow down the rapid growth of the skin cells, which occurs with psoriasis.”

She goes on to explain that sun exposure can also increase vitamin D levels, thus lowering inflammation in the body—another component of psoriasis.
