Derma needling - creating a controlled skin injury with tiny surgical needles to provoke better healing - has been a proven treatment for a wide range of skin rejuvenation applications since the 1990s.
Recent research confirms that ReJuveness derma rollers and stamps - which stimulate the skin's natural production of collagen and elastin - are an effective component in treatment plans to correct excessive and abnormal scars, including:
- indented acne scars
- mature older scars
- grey or white stretch marks
1. Used as a cost-effective alternative to surgical scar revision or ablation, self administered derma needling is "highly promising" as a treatment for reducing abnormal scarring.
2. Ordinary long needles, such as hypodermics, push cells aside, puncturing or cutting vessels and causing bleeding. Microneeding affects only the upper skin layer, causing minimal to no bleeding since only capillaries are punctured. The mild trauma creates a mild inflammatory response. Capillaries and fibroblasts migrate into scar tissue. Synthesized collagen fibers integrate into the skin matrix causing sunken scars raise to skin level and raised scars fall to skin level.
3. In one clinical study with acne scar patients, certain types of scarring decreased by nearly half with only three treatments at four month intervals, and and a "high level" of patient satisfaction.
In particular, it is a safe technique for dark skin, where risk of postinflammatory pigmentation is high with other scar revision techniques that more aggressively damage the epidermis.4
