I am a 42-year-old woman. I started using these products 4 years ago, after trying many other unsuccessful treatments (including antibiotics). My acne was mild but stubborn, and my skin always looked "angry". Now it looks calm and clean, and it only took about a month of treatment to change. It's made a huge difference in my life. I only use their products on my face, including the make up, which I highly recommend. I hope they never stop making it.
