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, and lax skin. 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 tissue. 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.
