You may be wondering, “How in the world is inserting hundreds of little needles into your face relaxing? And why would anyone want to do that?” It sounds crazy, but microneedling has a ton of benefits, including:
reduced wrinkles and stretch marks
reduced acne scarring and skin discoloration
increased skin thickness
enhanced product absorption
For anyone who’s looking for a way to tackle these concerns at home, microneedling might be your answer. Here’s what you need to know about this miraculous process.
Microneedling, often referred to as dermarolling or collagen induction therapy, is a cosmetic procedure in which thousands of tiny little needles are inserted into the surface of skin via a rolling or stamping device.
Dermarolling works by creating microscopic wounds which induce collagen and elastin production. If you didn't know, collagen is the most abundant protein found in the human body and is responsible for holding together connective tissue like skin, muscles, tendons, cartilage, and bones.
This lovely protein is also what keeps us looking young and gorgeous. Unfortunately, it's believed that collagen production slows down by about 1 percent per year after the age of 20, which translates to the big A word — aging.
Despite how terrifying dermarolling may seem, it's actually considered a minimally invasive procedure with little to no downtime. However, the recovery process does depend largely on the length of the needles used. Obviously, the longer the needles, the deeper the wound — and that means the longer the recovery time.
This will depend largely on what you're trying to accomplish. Since we're all about simplicity, here's a table summarizing what length should be used depending on what you're trying to treat.
Needle length (millimeters)
shallow acne scars
deep acne scars
0.25 to 0.5 mm
postinflammatory hyperpigmentation (blemishes)
0.25 to 0.5 mm
0.2 to 1.0 mm (start with the smallest)
sun damaged or sagging skin
0.5 to 1.5 mm (a combination of both is ideal)
1.5 to 2.0 mm (avoid 2.0 mm for home use)
uneven skin tone or texture
0.5 to 1.5 mm
Note: Microneedling won’t help postinflammatory erythema (PIE), which is redness or pink blemishes. And be aware that derma rollers or microneedling instruments that are greater than 0.3 mm in length are not approved or cleared by the Food and Drug Administration.
