How does dermarolling work?
Microneedling as a cosmetic treatment owes its origins to the pioneering medical research by burns and accident treatment specialists.
Medical research discovered many years ago that pricking the skin with tiny needles to no more than 1mm deep will stimulate healthy cell tissue regrowth without creating any scar tissue. The body responds to the tiny pinprick wound by starting up the normal wound healing response: increasing blood circulation and new cell regeneration.
The extraordinary success of microneedling in the treatment of burn scarring has naturally led to its popular use for cosmetic treatments as well. Dermarolling uses this same body response mechanism to stimulate the production of healthy new skin tissue.
The science behind derma rolling and acne scarring
Collagen is an essential protein that plays an important role in the formation of healthy elastic skin. In scar tissue, this collagen forms less flexible bundles of fibres than you find in normal healthy skin tissue.
Dermarolling breaks down the more rigid collagen patterns that make up scar tissue and also triggers the regeneration of more youthful skin tissue. The result is fuller, healthier skin.
A 2015 study measured the effectiveness of microneedling treatments on the reduction of atrophic acne scars in patients over a three-month period. The results were spectacular with 50 to 60% improvement in the appearance of acne scarring after just 3 months.
The health of the skin, as measured in epidermal thickness and the amount of new collagen and elastin, also showed significant improvements. Numerous other studies support these findings and indicate that skin health and appearance will continue to improve over longer periods of 6 months and more.
Can I use Dermarolling with other treatments?
There is normally no problem using Dermarol in conjunction with creams or lotions. Research indicates that the microneedling treatment will actually help absorption and improve the effectiveness of any creams you apply to the affected areas.
There are some indications that using a glycolic acid peel alongside dermarolling will actually increase the effectiveness of the dermarolling process. Some cosmetic surgeons use laser, dermal fillers or will make tiny incisions into the skin to remove scar tissue. Some of these treatments require a healing period and obviously, you will not be able to use your dermaroller during that period.
Many of these other treatments are both expensive and require repeat application. It makes sense to start with the Dermaroller and watch the transformation of your new healthy skin unfold before you try some of these other costly options.
What about collagen injections?
Collagen injections may help to fill in deep atrophic scars. You will need to wait for the inflammation to settle down before you can use your Dermarol again. The benefit of collagen injections is almost always temporary, and you will need to repeat the treatment regularly.
