Ask the Expert: Can Sunscreen Cause Acne?

Wondering if sunscreen can cause acne? We tapped board-certified dermatologist, and Skincare.com consultant, Dr. Dendy Engelman to help answer this burning question, ahead.

Sunscreen often gets a bad rap: it’s too heavy, it leaves skin looking ashen and greasy, and—perhaps worst of all—causes acne blemishes to form. The truth is, you shouldn’t believe everything you hear. Not all sunscreens are created equal, so while some formulas may leave behind less-than-ideal results, that’s not to say that all sunscreens will do the same. Applying Broad Spectrum SPF and taking additional sun protection measures is a critical part of every skin care routine, playing a significant role in reducing risks for visible signs of skin aging and even some cancers. Forgoing sun protection is a terrible—we repeat: terrible—idea!

To clear the air once and for all, we reached out to board-certified dermatologist, and Skincare.com consultant, Dr. Dendy Engelman. Can sunscreen really cause acne? Read on to find out!

SUNSCREEN 101

First and foremost, it’s important to understand the difference between the two types of sunscreen: physical and chemical. “Physical sunscreens sit on the top of the skin and deflect UV rays,” says Dr. Engelman. She warns that since some physical sunscreens can be thick in consistency, they may cause unwanted blemishes to form due to the blockage of pores from the formula. Chemical sunscreens, on the other hand, work to absorb UV rays, thereby reducing penetration into the skin. Some chemical sunscreens may feel lighter on the skin compared to physical sunscreens, but Dr. Engelman recommends scanning the product’s label for the word “non-comedogenic,” meaning the sunscreen was specially formulated so as not to cause blocked pores.

Another thing to consider before choosing an SPF? Your skin type! Applying a sunscreen that’s formulated for oily skin onto your sensitive skin can be a recipe for disaster. When in doubt, consult the product label or ask your dermatologist for a recommendation.

How to Use Sunscreen to Prevent Breakouts

Long story short: Yes, some sunscreen formulations can cause your skin to breakout. But, there are ways to help prevent sunscreen-induced blemishes. In addition to choosing the right formula—chemical versus physical—and keeping your skin type in mind, make sure to use your sunscreen the right way. Dr. Engelman recommends layering up with other skin care products before applying your sunscreen of choice, such as serums and moisturizers. “I would recommend a serum before applying any sunscreen,” she says. If your skin is prone to breakouts, adding in an acne-fighting serum prior to sunscreen use can help prevent pimples behind the scenes. “I would also advise a light moisturizer prior to applying sunscreen,” Dr. Engelman says. “The moisturizer can make a barrier on the skin while also protecting it.”
