A few weeks ago started SS-31, stopped all other peps except Reta because I felt it would help my other peps work better in the long run. When I was younger, I had eyebrows like Brook Shields. In my 40s they became thinner and I had lighter spots that I would get tinted. Today when I went to do my makeup, I realized my sparse eyebrow spots had filled back in, my eyebrows are fuller and my skin is so clear! Then I realized, I don’t think I’ve actually filled them in at all this week. Could it be the SS-31?
