Clindamycin
"I began to use Clindamycin PH 1% Gel and Sodium Sulfacetamide 10% and Sulfur 5% towards the end of the summer for 2 months for my issues with acne on my chin. I had bumps on other areas of my face but mostly concentrated in my chin. My acne its not severe but its always been an issue, and since I was 12 I always had black heads on my nose and chin. This gel did not work for I didn't notice any change on my face, the pimples, bumps and black heads remained the same, they became more noticeable. It was irritating on my skin and it made my skin extremely oily and since I wear  makeup it became an issue. The cleanser I do enjoy, it clears your pores and my skin has never been softer but the gel I do not recommend"
