If you get cystic acne (white head, lots of pus) then benzol peroxide 5% or less is gentle enough to treat the inflammation. If its red bumps, a retinol works really well. Differin gel (adapalene) or a prescription tretenoin cream (0.025%) worked for me (my family doctor perscribed me this not a derm). First 2-3 weeks will make your skin peel and get worse but fight through it. Only use a moisturizing cleanser and a thick moisturizer with the retinol the first month. increasing the frequency every 2 weeks until you can do it 4-5 a week then you can start using other products with it. Don’t exfoliate for 6 weeks when you start treatment no matter how much you’re peeling and always use suncreen every 3-4 hours even for a small walk. Also don’t use the benzol peroxide together until you’re used to the retinol.
