Secret RF is a skin rejuvenation treatment that combines microneedling and radiofrequency energy to improve skin tone and texture, with minimal downtime.Â
Developed by Cutera, it can address fine lines, mild wrinkles, stretch marks (striae), acne scars, hyperpigmentation, and other skin concerns on the face, neck, chest, and body.
Secret RF radiofrequency microneedling works by remodeling existing collagen and kick-starting your skin's natural development of new collagen, for firmer, more supple, and more evenly toned skin over time.
During a treatment, microneedles penetrate the dermis and deliver fractional radiofrequency energy into the lower layers of subdermal tissue, at various depths. This triggers a natural wound-healing response, which stimulates new collagen production and accelerates cell regeneration.Â
Your provider will customize the treatment for your skin concerns, using:Â
- A 25-pin or 64-pin tip: The narrower, 25-pin tip is ideal for use in small, delicate areas of the face. The wider, 64-pin tip can cover larger areas more quickly.Â
- Non-insulated or semi-insulated needles: Needles without insulation deliver heat along their full length, through all layers of the skin. Semi-insulated needles radiate heat from only their tips, embedded deep in the skin, which can be safer for people with olive or brown skin tones (who can be more prone to hypo- or hyperpigmentation).
- Adjustable 0.5–3.5mm penetration depth: Shorter needles can target more superficial concerns, like shallow acne scars, fine lines, or stretch marks. Longer needles can reach deeper into the skin, to trigger a boost in skin-tightening collagen production.Â
Collagen is the most abundant protein in the skin, providing structure and keeping skin firm and supple. Production slows in our 20s and 30s, leading to wrinkles and sagging.Â
RF microneedling treatments like SecretRF help reverse this process, while addressing a range of other tone and texture concerns.Â
"Compared to regular microneedling, Secret RF microneedling is a superior treatment," says Dr. Dmitriy Schwarzburg, a physician in New York City. "It amplifies the process of skin rejuvenation at the surface and cellular level. Heat created by the added RF energy also works to constrict underlying skin layers, to further smooth out even the most severe lines and wrinkles."
To see optimal results, most people need a series of three to four treatments, every four to six weeks.
