Microneedling refers to both the Dermaroller treatment and the Dermapen; it is also known as collagen induction therapy. Microneedling is a minimally invasive procedure used to rejuvenate the skin. It is most commonly used for the reduction of scars such as acne scarring, hypertrophic scars and surgical scars. It is also used for fading stretch marks, reducing fine lines and tightening sagging skin.
Dermaroller and Dermapen
The Dermaroller is a mechanical device that contains a wheel of microneedles. The Dermaroller is rolled over the skin in order to create a controlled area of trauma in the skin’s top layer. As each microneedle punctures the skin a small channel is formed. This stimulates the production of collagen and elastin in the deeper layers of skin. The microtrauma also leads to the formation of new capillaries (small blood vessels) reducing the appearance of scars and improving the texture of the skin.
The Dermapen is similar in that it uses microneedles to create a controlled area of trauma but instead of a mechanical device it is a smaller electronic device that resembles a pen. The Dermapen uses the same principal as the Dermaroller but instead of the rolling action, the Dermapen is moved backwards and forwards across the skin as the microneedles automatically go in and out of the device around 1000 times a minute. After the procedure your skin may be slightly red. This can last up to 4 days depending on the depth and intensity of the treatment you have.
Like with microdermabrasion, the top, dead layer of skin is removed and so the skin is temporarily much better at absorbing topical lotions. Any product applied to the skin during or immediately after a Dermaroller or Dermapen treatment is very easily absorbed into the skin, rendering it much more effective than with a traditional topical application.
