Hi. I have very oily and acne-prone skin and my aesthecian recommended G.M. COLLIN Acne Complex or Carita Ideal Controle Powder Lotion. I've been using the GM Collin complex, which also claims to have antibacterial properties, for almost a year. However, it is very expensive and I've been thinking about switching to the Carita but it has alcohol and I'm afraid that might make my skin produce even more oil. I've also used OC8 before, which I found to make my face even oiler after a few hours. Do these products really work in controlling sebum? Are there cheaper alternatives (I heard magnesium of milk works really well)?

These are the ingredients for the GM Collin Complex
