Does contratubex gel good to make acne marks fadeaway ?

Worthless junk: This is a mix of allantoin (the major component of bird droppings), onion, and heparin. Acne marks fade only with time. A depigmenting agent may remove the brown but you're more likely just to make a mess. Nothing you can do on your own helps the scars. I'm sorry you ended up like this. Topical benzoyl peroxide and perhaps a prescription-strength Rx may be your best friends if you've still got it.
