Micro-needling: Collagen Induction Therapy
Stars like Angelina Jolie and Kim Kardashian are rumored to be fans of Collagen Induction Therapy, also known as micro-needling. Collagen Induction Therapy is a minimally-invasive skin rejuvenation treatment designed to improve the appearance of fine lines, wrinkles, scars, and even stretch marks of the face and body by improving collagen production in the skin.
About Collagen in The Skin
Collagen is the main structural protein of the skin, it is produced by a cell in the dermis called fibroblast. Collagen works with elastin and keratin to provide tensile strength, firmness, elasticity, resilience, and skin density. Throughout life the activity of the fibroblast slows and the genes that degrade collagen become more active, as a result collagen levels continuously and progressively decline. Adding insult to injury, the quality of collagen is also degraded and less organized. There are a variety of influences that can further accelerate the decline of collagen, such as genetics, hormones, and sun damage. Collagen begins to decline in our 20’s, and by the time we are in our 40’s, it’s about half of what it was at 18.
Scar tissue is also composed of collagen, but the organization of the collagen is different. In scar tissue, the collagen is aligned in a single direction, instead of a random basket weave formation.
How it Works
Micro-needling delivers tiny needles into the epidermal and dermal layers of the skin creating micro-injuries. These micro-injuries to the skin break up old collagen strands which cause the skin to begin a natural wound healing or renewal process. During the renewal process, skin releases growth factor which triggers fibroblast proliferation, matrix production, followed by the deposition of collagen, elastin, proteoglycans, and GAGs. This tissue remodeling results in an increase of collagen production that is better organized. This collagen induction process can improve lines, wrinkles, scars, and stretch marks. Micro-needling is an exciting anti-aging option to induce collagen, even at an early stage.
The best part is, there is little to no down time, and, with topical anesthetic, it is very comfortable.
