Benzoyl Peroxide or Salicylic Acid: Which Is Better For Acne
Benzoyl Peroxide vs. Salicylic Acid: Which One Is Better For You?

Benzoyl peroxide, on the other hand, attacks acne-causing bacteria to treat and prevent pimples. "Benzoyl peroxide is highly lipophilic, which allows the molecules to penetrate the skin surface and target the hair follicle," said Dr. Lain. While it does help exfoliate the skin and clear pores, that is not its primary activity. But here's where it gets tricky for us in the UK. Simply put, it's not as easy to get your hands on benzoyl peroxide as it is salicylic acid. That said, stores like Boots and Superdrug now stock benzoyl peroxide in lower percentages on the shelves because in October 2019, the ingredient was formally reclassified from the pharmacy to general sale list. That's great news for people with diagnosed, mild acne. But remember, don't self diagnose and always seek GP or dermatologist advice if you need something a little stronger with a higher percentages since those are still available via prescription only.
Dr. Gross, who is admittedly not a fan of using benzoyl peroxide for acne, pointed out a couple of negatives about the ingredient. "It doesn't only kill p.acnes bacteria, it also kills good bacteria," he said. "Benzoyl peroxide is a free radical and actually damages skin while it clears acne. That means it injures normal skin cells and creates dryness, redness, and irritation all too often."
