An outstanding Collistar creation that ensures high concentration, purity and efficiency of the active principle. The special structure of this particularly rich cream has been specifically designed to optimize the transport of glycolic acid in the tissues, strengthen the acid mantle of the skin and give the skin extra care, elasticity and comfort. Collagen, literally the skin's natural support, is the most important of the proteins responsible for skin firmness. The attacks of free radicals and the passage of time cause collagen to progressively change and its production to slow down. As a result, the elasticity of the skin tissue decreases. Highly effective in fighting skin aging, 'Collagen Cream Balm' ensures a particularly fast, intense and targeted action, which helps to tighten and firm the skin, combat the loss of firmness and elasticity of the skin tissue, counteract the formation of wrinkles and the reduction of already existing wrinkles. Without fragrances, alcohol, dyes.
