Microneedling is a procedure in which a controlled injury is made to the top skin layer. The injury triggers a healing response from the body, thus stimulating the production of new skin tissues. Though the technique has risen in popularity over the recent years, its usage goes back over two decades. Microneedling is reported to have first been used for skin care in 1995 by dermatologists Norman and David Orentreich. They described the procedure as subcision for treating depressed scars and wrinkles. The following year, the microneedling roller was developed by cosmetic surgeon Dez Fernandez.

Generates New Collagen
It is widely reported that microneedling generates new collagen, which is more bountiful than any other protein in the body. Collagen is developed by cells called fibroblasts, belonging to the second layer of skin known as the dermis. The greatest amount of collagen is found in the skin, bones, and tendons. Collagen is linked to a number of health benefits, particularly regarding skin care. It is certainly well known that collagen helps diminish signs of aging like wrinkles, dark circles, and fine lines. It also enables the skin to maintain its structure.
In a study, sixty-nine female participants were given collagen hydrolysate or a control substance every day for eight weeks. Results showed greater improvement in skin elasticity of the participants in the collagen hydrolysate dosage group compared to those in the placebo group. Collagen is also reported to help protect against skin damage from the sun's UVB rays. A 2009 review states the daily usage of collagen peptides helped prevent the reduction of skin moisture and type I collagen by UVB rays in patients.

Treats Minor Scarring
Microneedling also treats minor scarring as it helps repair damaged tissues in the skin. The results of microneedling on acne scars have been widely investigated. A 2015 study is one of the several to assess the procedure's effectiveness. Over the course of three months, ten Egypt-based participants (half male, half female) were given treatment every two weeks. Following treatment, the patients were instructed to use topical antibiotics and sunscreen of at least thirty SPF for protection throughout the day. Scars were improved fifty to sixty percent three months following initial treatment. Furthermore, it is shown microneedling can treat non-acne scars as well such as those induced by surgery, burn injuries, trauma, and chickenpox.
