How does sun exposure affect acne?

While exposure to the sun is not proven to increase the risk of acne, it has been proven to increase the risk for skin cancer and speed the aging process. It is important to use a sunscreen when you are exposed to the sun, to avoid the potentially damaging effects of UV rays.
The sun is deceptive. An hour on the beach today may dry up your acne a bit so that it looks better tomorrow, but a few days later, it’s likely to be worse: more bumps, inflammation, and redness. Your skin reacts to the UV radiation by becoming inflamed; it reacts to the stress of those damaging rays with its own stress-response system, which can trigger acne and other troubling skin conditions. You may not see this for several days after sun exposure, and this delayed reaction can make you forget that it was the sun that caused all this to begin with. Save yourself the aggravation, and spare your skin the sun damage.
