The pen will create micro injuries to the skin, which will trigger growth of fibroblasts, which in turn stimulate collagen production. The reason we get more fine, lines and wrinkles as we age is decrease in collagen production. The increase in collagen production from the skin needling treatment will help create smoother, plumper skin.
What I love about the skin needling is that it only enhances and improves the duration of other treatments such a botox/dysport and dermal filler treatments. The better quality of your skin the more improved response and results you will see from other treatments. After my experience with this treatment, I definitely recommend putting this one on the bucket list for healthy glowing skin.
