Secret RF - The Advantages of Fractional vs. Traditional Microneedling
Photodamaged and aging skin is characterized by the thinning of the epidermis and dermis and is associated with a decrease in collagen levels resulting in fine lines, wrinkles, tone and texture changes. Treatment of photoaged skin is based on inflicting damage to the dermis, resulting in neocollagenesis. Damage to the dermis results in the upregulation of the activity of various enzymes, such as metalloproteinases and collagenase that are responsible for the removal of old tissue and deposition of new dermal tissue1. Traditionally, laser-based technologies are used to resurface the skin. However, these treatments vary in their efficacy, adverse effects and downtime after treatment.
Recently, fractional radiofrequency (RF) microneedling has emerged as a treatment option. Rather than impacting the entire surface, microneedling causes thermal damage to the dermis in microscopic zones. The intact surrounding tissue accelerates the wound healing process, reducing recovery time and resulting in minimal adverse effects.
Fractional RF microneedling is a minimally invasive technology that involves the use of an array of very fine sterilized needles to create microscopic wounds at various predetermined depths in the dermis, without affecting the epidermis. The delivery of energy leads to the creation of an array of microscopic wounds in the dermis, interspersed between intact tissue. The direct thermal heating of the dermis results in new collagen production and subsequent dermal thickening. The presence of the intact epidermis and the surrounding dermal tissue results in rapid re-epithelialization and thus minimal downtime and risks. Microneedling is effective in the treatment of scars, acne, wrinkles and other signs of photoaging and photodamage. Studies also show that fractional radiofrequency microneedling is effective in the treatment of acne scars2,3,4and wrinkles5.
What I appreciate about Secret RF is that I can customize each treatment to the individual patient I am treating, and because we have two needle types, the treatments can be performed on all skin types and all year round. Manu Aggarwal, M.D.
