I have recurring acne problems on my chest for years, and I have tried many methods to no avail. I came to know about R3 through a friend, at first, I just think of giving R3 a try, unexpectedly, I continued to take R3, one sachet a day, after three months, the acne on my chest was greatly subsided. My cells were repaired, thus my skin has become healthier and better, simply marvellous!
