Radio-frequency (RF) is a safe, painless, and non-invasive skin treatment to tighten sagging skin and reduce wrinkles. When radio-frequency goes into your skin, it delivers heat to the tissue, stimulating collagen and elastin production. This helps to tighten the skin and diminish the appearance of wrinkles, resulting in a smoother and more youthful complexion. It also promotes blood circulation, improves skin texture, and enhances overall skin tone.
