I use salicylic acid.  I find it more suitable and gentle on my skin.  Aside from clearing my face, it acts as an exfoliant as well.  The copper peel from omorovicza also works well on my skin. 

I find that it depends on your skin for which works best.  Sometimes a combination of Benzoyl Peroxide and Salicylic Acid even works well for some.

I use a moisturizer with salicylic acid, and then use a 2.5% spot cream with benzoyl peroxide. It works best for my skin, but everyone is different. I normally have very mild acne (white heads) and this regimen keeps it under control for me. It's all about finding something that works for your type of skin.

I actually prefer using tea tree oil for any of my breakouts.

Do you suggest a benzoyl peroxide cleanser? Because sometimes i get chemical burns wit the one i used.

I don't really notice the difference to be honest, but BP seems to work just the tiniest bit faster than SA in my case. If you are getting chemical burns I would suggest seeing a dermatologist.

Ive had a lot of luck with the Clean and Clear Continous Control cleanser. Its 10% BP though so if thats to strong you can try the C&C advantage 3 in 1 exfoliating cleanser which is 5% BP.

If your skin isn't to sensitive, you could try using a salicylic acid cleanser in the morning and a benzoyl peroxide cleanser at night. I used to do that because I used to have both cystic acne and whiteheads so each issue was addressed.
