Unnoticeably,
awakening your skin’s natural balance — Double Tight · Skin Booster
Treatments for natural-looking results and healthy skin recovery.
With Double Tight, RF energy is delivered simultaneously to the papillary and reticular dermis, then a skin booster tailored to your condition is added—refining texture, elasticity, hydration, and tone for balanced change from within.

Irritation is minimized, and the effects gently rise from deep within the skin.
