Microneedling may reduce fine and deep wrinkles
One of the main benefits of microneedling is its ability to stimulate the growth of collagen and elastin, which is the key to new, youthful-looking skin. Because of its ability to trigger the generation of new skin cells, dermatologists have found that a few sessions will noticeably reduce fine lines, crow’s feet, and deep wrinkles on the forehead. “This is one of the reasons I like microneedling—because it’s able to use the body’s own natural healing mechanisms, so the results are very natural,” Dr. Shah says. “And because there’s minimal downtime with it, I often recommend it as maintenance for people who are trying to stave off the signs of aging.” To treat wrinkles, a needle no longer than 1.5 mm should be used.
Microneedling may repair visible scars
In a study on the effects of microneedling published in the Journal of Cutaneous and Aesthetic Surgery, nearly 100 percent of acne-scarred participants reported a marked improvement in the visibility of their scars. With at-home microneedling, a 1.5-mm handheld roller is long enough to improve the appearance of acne scars. For severe acne scars, however, you may need longer needles for maximum results. Professional grade microneedling devices (used in a dermatologist’s or facialist’s office) can be as long as 3 mm, which will treat deep acne scars that occur beneath the surface of the skin. How effective is microneedling compared to fractional laser treatments for reducing acne scars? Research in the journal Dermatologic Surgery in 2016 found both treatments to be comparable and effective but gave credit to microneedling for being better tolerated, with fewer side effects and less downtime.
Microneedling may reverse sun damage and pigmentation
Collagen is arguably the best way to improve the look of skin, and this goes beyond reducing wrinkles. Stimulating collagen growth with microneedling can also reverse sun damage and discoloration, including the hyperpigmentation that comes with melasma. A study in Brazilian Annals of Dermatology showed microneedling to be a promising treatment for the blotchy, brownish facial pigmentation that comes with this chronic condition. To improve extra pigmentation from sun-damaged skin, dermaroller needles should range from 1.0 mm to 1.5 mm in length.
Microneedling may help aging skin
In addition to its ability to smooth and correct damaged skin, microneedling can also tighten loose skin in older men and women. (Remember: The older you are, the less collagen you’re naturally producing.) A study in the International Journal of Dermatology found that microneedling is a new way to achieve “skin rejuvenation, tightening, and scar remodeling” and that it offers a “simple and effective treatment for photo-aged skin,” according to the researchers, with minimal side effects and downtime. Also helpful: avoiding these habits that are making you age faster.
Microneedling can be done all over your body
Another microneedling benefit is that this treatment isn’t exclusive to the face. It can be done on any area of skin that needs to be repaired—including areas that display stretch marks or acne scars, like the legs, chest, back, and butt. Four to six sessions could make a difference in these areas, says Dr. Shah. Next, check out these 20 ways dermatologists wake up with younger-looking skin.
