How can the sun affect acne?

Affects In Both Ways: Sun exposure initially can improve the appearance of your acne. A slight tan can definitely even out your skin tone. But over time the effects of the sun can damage your skin by increasing oil production and clogging pores, leading to an increase in acne. In addition, the sun’s ultraviolet rays can age your skin and cause cancer.

Not alot: Sun does not generally affect acne but it in some individuals who are more prone to post-inflammatory hyperoigmentation may be experience increased darkening of the acne affected areas if exposed to the sun. Use non-comedogenic sunscreens in this instance.
