Collagen is one of the most important ingredients for skin rejuvenation, necessary for growth, regeneration and nutrition. This serum is formulated with Peptan® Collagen Peptide, hydrolysed marine collagen which is a 100% natural ingredient. It contains 18 amino acids necessary for natural collagen synthesis in the skin. Due to the small molecule size, it can penetrate deep into the skin, so it has a specific effect on the deep layer of the skin. Mixed with a face cream it can increase its effectiveness, or use as a stand-alone skin care product in the morning and evening.
