I have had it for 3 weeks and I feel and see a huge improvement in my skin! I have a lot of sun damage and dry skin. I use it 4 times a week and it takes me 5 to 10 minutes (depending on how many times I choose to go over a certain spot) to do my face and neck then I apply a vitamin C serum all over and once that soaks I apply my night cream. I do this at night obviously. The first 10 days I could feel a difference in the way my skin felt and soon after that I could also SEE a difference toođź‘Ť Where I see a huge difference is my neck, forehead and around my eyes.... hope this helps
