How does it work?

A derma-roller contains hundreds of tiny needles. When in use, these needles create micro-injuries on the skin, which in turn sends collagen and elastin production into overdrive to compensate as it heals—leaving your complexion tighter and plumper than it was beforehand. This makes it an ideal method for filling in fine lines and wrinkles, thickening and plumping the skin under the eyes (thus diminishing the appearance of dark circles and bags), and even plumping up lips. Micro-needling is also a very effective treatment for acne scars and discoloration since it penetrates the skin so deeply. Plus, when used in conjunction with a serum (as it should be), it boosts ingredient absorption up to 90%.

For a more intense, in-office treatment, many dermatologists use a derma-pen, an electronic micro-needling device that oscillates as it punctures the skin. These treatments often have immediate and dramatic results but also have side effects like pain and bleeding. They also tend to be very expensive.

Fortunately, at-home derma-rolling is a much thriftier alternative that still gets great results with regular maintenance. It requires a much lower pain threshold, too.

How does the derma roller repair acne scarring?

The derma roller (or derma stamp) works by causing a ‘mini-trauma’ to the skin, activating the skin’s healing process. New collagen and elastin is produced, creating brand new skin cells that will fill out any pitted scars or indentations. At the same time,  scar tissue is ‘tricked’ into dividing and is gradually broken down.

After a few treatments, scar tissue starts to contract and hyperpigmentation begins to fade. The derma roller also thickens the skin, which simultaneously makes scars less visible. With time and continued treatments, most scar tissue is removed and replaced with smooth, healthy skin.

Using a derma roller also creates channels through which products can penetrate to deeper skin layers and therefore work much more effectively than they would normally. Combining derma roller treatment with the right products can dramatically speed up the repair process.

Vitamin C serum is the secret weapon for scar removal. Our bodies need Vitamin C to produce collagen and using vitamin C serum in conjunction with a derma roller/derma stamp combines collagen production with new skin cell generation. Vitamin C also fights hyperpigmentation by preventing melanin production. This is beneficial when treating acne scars, as it helps to fade the marks left behind by acne and/or acne scars.
