Secret RF explained

Secret RF is a fractional radiofrequency microneedling device developed in Korea and distributed internationally by Cutera. It is used for acne scars, enlarged pores, fine lines and mild laxity. It can also treat the neck and some body areas.

How Secret RF works

Thin needles enter the skin to a depth set by the doctor, often between 0.5 and 3.5 mm. Each needle releases RF energy, which creates small heated zones in the dermis. The skin heals these zones by producing new collagen and elastin. Because heat is delivered below the surface, it can be used on many skin tones with careful settings.
