We have added "Massage Peel," a peeling treatment that stimulates collagen production and provides firmness, radiance, and whitening, simply by applying it to the skin. This peeling treatment works on the dermis layer without damaging the surface of the skin. By gently massaging the skin while the treatment solution is applied, it works on the deeper layers of the skin, powerfully promoting collagen production and stimulating epidermal regeneration, resulting in firmness and transparency.
