HP VITARAN is a Skin Booster that injects polynucleotide (PN) purified from the reproductive cells of salmonid fish into the dermis. PN, which has a structure similar to human DNA, improves the skin's regenerative environment and helps soothe irritated skin. At the same time, it enhances the skin's ability to retain moisture, alleviating inner dryness. With repeated treatments, skin texture becomes smoother, and elasticity and brightness improve together.
