Simply put, microneedling is the insertion of very fine short, sterilized needles into the skin for rejuvenation, explains Macrene. When the skin feels these pinpricks, your body will naturally rush to heal them, resulting in a plumped, more youthful appearance. The most popular (and cost-effective) microneedling device, a dermaroller, comprises micro-fine needles that range in diameter from 0.5 and 2.5 millimeters. But, if the prospect of multiple needle wounds sounds slightly ominous to you, know that the punctures are more like pinpricks that enter only surface-level deep.
"From microneedling alone, you will look plump, pink, and luminous for a couple of weeks. On a short-term basis, it plumps the skin and makes the skin look more radiant from inflammation and very superficial swelling," Alexiades says. However, because the efficacy of microneedling comes from the skin healing itself, some people may only see intense results after a few sessions.
