Microneedling through the use of a derma roller or other microneedling device helps to create a more youthful appearance. It does this by inducing collagen and elastin production, and this results in firmer, smoother and more elastic skin. Skin which has these attributes is, in essence, more youthful.
Is This Backed Up by Science?
Yes, a number of research papers have been done on microneedling for younger-looking skin. For instance, check out the below quotes from two papers:
"A significant increase in level of collagen type I, III, and VII, newly synthesized collagen and tropoelastin from baseline was observed after 6 microneedling sessions at 2-week intervals by El-Domyati. This percutaneous collagen induction leads to an overall youthful appearance of the skin by reducing fine lines and wrinkles, reducing pore size, more suppleness, and elasticity." - CLICK HERE FOR SOURCE.
"One single microneedling causes tiny wound (sic) in skin and as a result of post traumatic response platelets are released, which produce a series of growth factors that promotes the body's own production of collagen and elastin. It is a safe alternative for the treatment of post-burn injury, wrinkles, stretch marks and for smoothing of skin without the risk of dyspigmentation or scarring." - CLICK HERE FOR SOURCE.

Which Needle Length Is Best to Achieve Younger Looking Skin?
We generally recommend shorter needle lengths for this purpose. Anything from 0.30mm to 0.75mm will do well. Most people go with a 0.50mm unit.
You may treat your face once per fortnight if using a needle length of 0.75mm or shorter. Remember, your skin needs time to heal. Overzealous treatments will do more harm than good.
