Thanks, do you have a source?

True/False? “Benzoyl peroxide creates free radicals and is known to cause premature skin aging, just like repeated sun exposure or persistent acne.”
Rest assured, this is inaccurate. Such statements are a misunderstanding of how benzoyl peroxide functions on skin. It stems from confusion over the differences between benzoyl peroxide and hydrogen peroxide, and lumping all free radicals together as bad. Surprisingly, that’s not the case.
It’s true: not all free radicals are bad for you. Free radicals serve a critical part of your body's function: we actually need them to stay alive. Like most things, in moderation they can be beneficial. It’s when free radicals get out of control that problems develop. Of course, some types of free radicals are always damaging, especially hydroxyl radicals, which react quickly, causing immediate and lasting damage to skin.
Hydroxyl radicals are produced by hydrogen peroxide; benzoyl peroxide does NOT produce hydroxyl radicals. Benzoyloxyl radicals result from benzoyl peroxide, and convert into phenyl radicals. Phenyl radicals are not as damaging as hydroxyl radicals, and since the reaction leading to damage occurs quickly, the damage is brief and fleeting. This is no more harmful than the free radical damage that occurs to your skin from simply being surrounded by oxygen, and such a reaction is easily countered by products containing antioxidants.




Benzoyl peroxide radicals are short-acting and sensitive to such an extent that mixing an antioxidant-rich product with benzoyl peroxide reduces its effectiveness as an anti-bacterial ingredient. This is why we recommend allowing a product medicated with benzoyl peroxide a few minutes to dry before applying your Paula's Choice serum and/or moisturizer.


It is true that benzoyl peroxide has a drying effect on the skin which is desirable when treating the excessive sebum and blocked pores characteristic of acne. But I am not aware of any evidence that its use is linked to skin wrinkling long-term, and Internet discussions about free radical generation do not make any sense. Most wrinkling is due to photodamage (excessive UV damage) which is due to collagen and elastic fibre damage in the dermis - not on the surface of the skin where BP works. Untreated acne causes scarring which will make some facial lines more prominent or cause them to distort when you get older and chronological ageing sets in, so please keep on treating your acne. BP has stood the test of time and has no associated bacterial resistance problems if you can tolerate it (remember to build up slowly)



This is 50 years old over the counter product that is legal and used everywhere , if it were to age you we would know by now. Don’t worry

It dries the skin out and can potentially irritate it, not necessarily ageing it.
It's only banned in the EU in cosmetics. Its still available as an OTC drug.

There’s way better alternatives than to waste money on bp, op shouldn’t use it either way

Some people have great success with it, some don't, it's just one of those things unfortunately.

Thank you for the long response.
