This can create the illusion that sunlight is healing your acne—perhaps the root cause of this common myth.
However, the type of dryness produced by UV damage isn’t the same as the drying effect skin medications like tretinoin can have on acne-prone areas.
Does Sun worsen acne?
How does sun exposure affect acne? The sun’s ultraviolet rays can increase inflammation and redness, and can cause post-inflammatory hyperpigmentation (dark discoloration). Some acne medications may make your skin more sensitive to sunlight.
Does sunlight kill acne?
Doctors used to treat acne with ultraviolet (UV) light — the type of radiation that comes from the sun. UV light clears up acne, but it can also damage the skin and cause cancer. Blue and red light therapy kills acne-causing bacteria without damaging the skin.
Is a little sun good for acne?
While a little bit of sun every day is good for the skin, too much can bring on a whole host of problems. The sun’s rays can cause dryness and the buildup of dead skin cells, which can promote acne.
Is Sun bad for acne scars?
About 10 to 15 minutes a day of sun exposure can be beneficial for acne, especially on the body. However, anything longer than that can seriously harm your skin and make the acne worse. Sunlight causes inflammation which can cause hyperpigmentation, or darkening, of your scars.
