Collagen is a protein that forms part of the dermal connective tissue and provides the skin with turgidity and elasticity. Over time, these fibres become fragile and smaller in diameter, leading to a loss of elasticity and firmness. Collagen hydrolysate is able to stimulate collagen synthesis and increase skin smoothness. Matrixyl® also stimulates collagen synthesis by regenerating connective tissue, helping to maintain elasticity and restoring the characteristics of youthful skin. Hydrolysed elastin increases the skin's biodynamic properties, restoring suppleness and elasticity. Lactic acid is an alpha hydroxy acid that has a rejuvenating action by stimulating epidermal renewal. It is also an important moisturising agent and helps to lighten skin blemishes. Soy extract enhances the moisturising action and helps to reduce water loss. After applying the cream, there is an immediate firming effect due to its dimethylamino ethanol (DMAE) content, a natural nutrient that increases muscle tone while tightening, firming and tightening the skin.
