Microneedling increases the production of collagen and other healing factors by causing tiny traumas to the skin.
Collagen is an essential protein that helps keep the skin looking youthful, with a firm, smooth, and stretchy texture.
Aging causes the decline of collagen in the skin, contributing to wrinkles and other signs of aging.
Skin can also lose collagen due to injuries, such as acne scarring, stretch marks, or other scars.
It is important to realize that microneedling is not a quick fix, as it involves the growth of new skin. It can take several months for a person to see the full results of the procedure.
What are the benefits?
A 2018 systematic review found that microneedling is a safe and effective way to rejuvenate skin and treat scars and wrinkles.
The researchers acknowledged, however, that determining whether microneedling is a viable treatment option in all cases will require further research.
A press release from the American Academy of Dermatology also states that people can expect a reduction in the “appearance of large pores, fine lines and wrinkles, scars, and stretch marks.”
What are the risks?
The medical community generally considers microneedling to be safe and effective, but there are still some risks.
The primary risk is skin irritation after the procedure. Other side effects could include:
-
swelling
-
discomfort at the site
-
redness
-
bruising
