Dipeptide-2, composed of valine and tryptophan, can improve eye skin problems such as puffiness and dark circles. It relieves eye problems by inhibiting the activity of angiotensin-converting enzyme (ACE) and promoting blood circulation and lymphatic circulation. In addition, as a natural moisturizing factor, dipeptide-2 helps maintain the integrity of the skin structure, promotes healing and regeneration, and may promote skin protein synthesis and amino acid absorption.
