Can some ingredients increase sun sensitivity?

There are a number of pharmaceutical ingredients that can cause photo (sun) sensitivity. If you are taking prescription medications, consult with your healthcare provider or pharmacist for such concerns.

As for commonly used skincare ingredients, very few are photosensitizing, but some may appear to make your skin more prone to sunburn. That’s because leathery, sun-damaged skin often has a thick, dead skin layer that when normalized with retinols and hydroxyl acids may temporarily result in sun sensitivity. Using products that exfoliate the outermost layers of the skin like retinoids and hydroxy acids may temporarily result in sun sensitivity. If you believe your skin is allergic to an ingredient, it is best to discontinue use and contact your healthcare professional for further guidance.
