Thanks to the background of the parent company and years of research in nutrition and biotechnology, this brand has been able to produce consumer Retino products (as one of the first in Korea) that caught the attention of many skincare enthusiasts upon its launch.

The best-known line is the Retino Collagen line that uses 300 dalton (micro molecules) water-soluble collagen that can actually be absorbed by the skin when applied to the skin surface and does not remain on the surface, unlike large sized collagen. Thanks to patented Flexible Liposome^TM (Patent No.: 10-2081180) technology, the active ingredients are absorbed faster and deeper into the skin. In addition, the products of this line also contain the so-called Elastic Collagen ingredients combination such as collagen-generating Retinal (stabilized 3rd generation), Hyaluronic acid and Elastin. They also happen to be one of the first brands in Korea using Retino in skincare products.
