Acne scarsIn a 2014 study of 31 people, radiofrequency microneedling moderately improved acne scars in 58 percent of the participants. A small 2017 study found similar results.
Skin rejuvenationMicroneedling with radiofrequency waves can also improve the look of your skin. In a 2013 study, for example, the procedure reduced wrinkles around the eyes. The effects lasted longer than Botox injections. A 2020 case report also shares that the treatment can reduce loose facial skin. Additionally, in a 2018 study, radiofrequency microneedling improved skin texture and pore size.
HyperhidrosisAccording to a 2019 study, the procedure can permanently treat hyperhidrosis or excessive sweating. A 2013 study found that the treatment helps by reducing the number and size of sweat glands.
When to expect resultsYou’ll see results after 3 to 6 months. The exact time frame depends on the type and severity of your condition. In most cases, you’ll need at least four sessions. This also depends on what you’re treating. For example, if you have moderate acne scars, you’ll need about three or four treatments. Bigger scars might need ﬁve treatments. These sessions will be done every 3 to 8 weeks. This lets your skin heal between treatments. After the initial set of treatments, the results will last about 1 year. It’s recommended to have a touch-up session once a year to maintain your desired results.
