Probably as I put too much dosage on my face, I felt the skin on my face was pickled and I can see some
wrinkles on my face. 4-5 days later, ances disappeared. However, I feel my skin is not as healthy as before since that. In the past, as I have dry skin, I have no ances on my face. But right now, even though I still have dry skin, I can always find out some little ances wounded by the shaver, sometimes they are serious, sometimes not. My skin got many ance scars. How stupid I am!
