My friend's skin problem

I had chatted my friend the other day and was able to see her on webcam.I felt sad when I saw her that her skin problem is back again.I thought it was already healed.Her acne is active again.I told her what happen to her face again and she was sadly told me that maybe her skin adopted the acne treatment she used before and is now back.Again she's searching for another acne treatment and saw this product called Acnepril.I just told her she has to know first if it's effective and safe for her to use.I hope she will really find the treatment taht will really end her skin problem.
