Do AHAs cause sun sensitivity?
Yes. AHAs will increase skin sun sensitivity and should therefore always be used in conjunction with an SPF 15 or greater sunscreen. Other preventative methods that can be taken are choosing to wear a hat with a wide brim at least 4 inches wide, wearing lightweight sun protective clothing, and staying out of the sun when its rays are the strongest, between 10:00 a.m. and 3:00 p.m.
