Acne scarring and the sun and is sun bad. The sun can lead to hyperpigmentation to the scars if they are new. So you want to stay out of the sun if you have any new lesions from acne. Anything red and irritated can hyperpigment.

How the sun affects your acne scars

UV energy from the sun causes sunburn but also causes all scars to appear more red or purple. The older scars are effected less than fresh new scars. Therefore the use of strong sunblock (SPF 40 or higher) should be used generously and often. Reapplication every two to three hours is also recommended because sweat and air drying dimishes the sunblock's affect. Active acne breakouts (pimples, blackheads or blemishes) will react with excess sun exposure by  turning red or becoming darker secondary to stimulation of the surrounding skin pigment cells, a condition called reactive hyper-pigmentation.  Since putting on sunblack may irritate the active acne breakouts, try to avoid  prolonged sun exposure with this condition.

The sun and acne scars

The effect of the sun on scars depends on many things. The type of scar and your skin coloring being those that I think of first. If you have skin that pigments easily sun exposure is likely to cause post inflammatory hyperpigmrntation-dark spots. It is easier to prevent this than to get rid of it so be sure to wear sunscreen.
