I'm 65 now, and I had a terrible case of cystic acne ,started when I was 12 I was made to take antibiotics for years, I got a face lift at 35 and 3 chemicals peels to try to fix the scars, I've have done 2 Glov treatments @ it's hard to tell but I'm not giving up, it has a feel to it that its working, And I eleven lines on my forehead so I go over it a bit more, I love this ,wish I had it 45 yrs. ago
