Microneedling is also known as collagen induction therapy. It creates small wounds on the skin leading to the natural wound healing process. This cascade induces the production of collagen and elastin and allows the deep penetration of active ingredients like hyaluronic acid and antioxidants. It is a rapid treatment without side effects for all skin types. When performed by a doctor, microneedling allows for a more effective treatment due to the depth used. Dermapen 4 is the latest generation of microneedling devices and gives visible results, even after one session.
