THE DDS (DRUG DELIVERY SYSTEM) TECHNOLOGY The hydrogel used in the collagen mask is developed using patented technology based on the DDS (Drug Delivery System). The hydrogel formula, based on the principle of DDS, releases the essence with control over speed, time, and location according to the condition of the skin, its needs, temperature, and pH level. This allows for the most effective delivery of active ingredients to reduce wrinkles, moisturize, and nourish the skin.
