Home Cosmetic Science Talk Formulating Skin Is 2% salicylic better than 5% or even 2.5% benzoyl peroxide for acne as said here?

    I occasionally get hormonal acne although retinol (and sometimes prescription tretinoin) is part of my daily routine. In such cases I stop retinol and switch to 20% Azelaic Acid for a couple of days. Works like a charm for me [forum member advisory:anecdotal opinion content].

    Tried benzoyl peroxide once and spent a night in an emergency room with severe allergy. To be fair to benzoyl I had no acne next day :)

    What percentage BP did you use?
    What was the side effect?
    Did you only use in face or larger body part? 

    5% which I bought in a pharmacy over the counter.
    My face got swollen to the point where I had to use fingers to open my eyes and when my tongue started swelling I rushed to ER. They gave me steroids but it took 5 days for the swelling to go away.
     I didn’t even applied it on whole face. I used it as a spot treatment on 5 spots.

    The strangest thing is that my skin is an opposite of sensitive. I can use products with pH of 2 without irritation. I can use tretinoin and glycolic acid the same day you name it. It was the first time I had a reaction on something  that I applied on my face.

    Interesting. 

    Is it possible that only that specific product or batch had some problem like contamination or something else or you are sure it was BP?

    Long time ago i made lotion with anionic and cationic ingredients together and upon applying to face it was causing tightness of chest and difficulty of breathing. Removing ether cationic or anionic material solved the problem.

    Haven’t tried first two ingredients on my face but it’s probably just benzoyl.

    it’s a great ingredient that is effective for many people. I am probably just allergic. That’s kind of unavoidable. Amongst millions of users there always would be several who are allergic:)
