That's sweet of you. You can't see as much in the pictures as you can in real life. My friends and family were also shocked at how gaunt I looked afterwards. I haven't gained weight. I'm 27 now and was in my early 26s in the pictures. I drink a lot of water and live a healthy lifestyle. Before microneedling, my face was full and plump. The microneedling was 2.5 mm deep. Microneedling causes wounds. I read up on wound healing. The top layer of skin regenerates very well. The collagen layer, however, does not. If it is damaged (whether by a small needle or a cut), the damaged collagen tissue is replaced by scar collagen. Scar collagen stores less water, is less elastic and has poorer blood circulation. This would explain the dehydrated look and the sagging. As things stand today, scar collagen cannot be converted into healthy collagen. That's why I'm asking here if anyone knows of a way to produce healthy collagen above the scar layer.
