The new décolleté and bust care product from COLLISTAR combines two valuable ingredients – collagen and hyaluronic acid – which have long been actively used by professional cosmetologists. Collagen is responsible for the density and elasticity of tissues, fights against the loss of tone and elasticity of the epidermis, and prevents the appearance of stretch marks. Hyaluronic acid contributes to the restoration of skin firmness and elasticity, stimulating the metabolic processes of skin cells. With regular use, the skin becomes denser, more resilient, and smoother.
