Acne Scars: Micro-Plasma, Microneedling, and Silicone

Posted April 2021 by Biodermis
In recent years, new and improved methods have been developed to treat acne scars and reduce common signs of aging. In this article, we will look at how radiofrequency (RF) is used in conjunction with micro-plasma and microneedling-based treatments and why these are effective options for reducing acne scarring. Alternatively, medical silicone, which has been around for a long time, can also be used to effectively treat certain scar types.

Acne scar radiofrequency treatments

What is micro-plasma?

Plasma is a gas that contains ions and has a net electrical charge. It is one of the four essential states of matter alongside liquids, solids, and gasses. Scientists estimate that about 99% of the visible universe is made up of plasmas. Microplasma is a plasma with very small dimensions that can be used as a source of energy to activate chemical reactions. In the case of acne scarring, a specialist will induce microplasmas to the specified area, triggering molecular breakdown. With Micro-plasma RF therapy, low bursts of energy radiation are delivered to the dermis layer of the skin. The heat generated by this radiation breaks down old collagen cells to stimulate the production of new collagen, thereby reducing acne scarring and signs of aging.

Microneedling RF

Microneedling is another way skincare specialists can stimulate collagen production in areas of the skin with collagen degradation, such as is the case acne scarring. The process of microneedling involves pricking the skin with very small needles to create microscopic punctures in the skin. This minimally-invasive procedure dates back to 1995 but as new technologies have emerged the practice has become more and more popular. Such a procedure provides almost immediate results and can be performed in any dermatology office or medspa. While prices can vary, the cost is usually quite high, especially if multiple sessions are needed.

A comparison

Both microplasma and microneedling treatments can be done using radiofrequency (RF). RF uses electrical heat energy (unlike laser and LED treatments that use light energy) to stimulate collagen and elastin synthesis in the skin. RF treatments can be used to treat acne scarring, tighten the skin, help with stretch marks, and reduce sagging to create a more youthful look. The typical RF procedure will take anywhere from 20 to 45 minutes with minimal recovery time. Some patients may experience reddening in the treated area after the procedure but this should go away on its own after a short while. In one study, both micro-plasma RF and RF microneedling were shown to be effective for the reduction of atrophic and rolling acne scars. Micro-plasma RF was shown to be a more efficacious treatment option, but RF microneedling had fewer side-effects and a shorter recovery time.

Non-surgical scar treatment

Topical silicone gel is a clinically-proven method for treating hypertrophic and keloid scars and has been used by dermatologists and surgeons for over 30 years. While silicone will not restore collagen loss characteristic of certain types of scars, it will help to flatten and reduce discoloration in other scar types. Topical silicone works through the mechanisms of dermal hydration and collagen regulation and is a safe option for children and adults. Silicone is hypoallergenic and non-comedogenic. Medical silicone can be purchased through your physician or online at biodermis.com.
