Yunth Launches New Serum and Mask with 100% Pure Raw PDRN and Astaxanthin, Pre-releasing on June 5

Ai Robotics Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Makoto Tatsukawa) is launching new items in its skincare brand Yunth's raw serum and sheet mask series: the 'Nama PDRN-α Serum' and 'Nama PDRN Sheet Mask (Pure PD Mask),' scheduled for sequential release from August 2026. Prior to the general sale, a pre-release will begin at Loft on Friday, June 5, and at other variety stores from Friday, June 26.

In recent years, with the spread of aesthetic medicine, interest has grown in 'suikou-hada' or 'water-gloss skin'—a radiant, dewy complexion that appears to glow from within. Among various ingredients, PDRN has garnered attention, particularly among highly beauty-conscious consumers.

Yunth, which has focused on 'delivering 100% pure ingredients in a fresh state,' has now turned its attention to salmon-derived raw PDRN*1 as its next key ingredient, launching the 'Nama PDRN-α Serum' and 'Nama PDRN-α Sheet Mask.'

The 'Nama PDRN-α Serum' is a high-concentration*2 serum formulated with 20,000ppm of 100% pure, liposome-encapsulated raw PDRN*1. It is further enriched with astaxanthin*3 and 7D non-cross-linked hyaluronic acid*4, leading to plump, deeply moisturized 'water-gloss skin'*5. The product features Yunth's unique individual packaging, ensuring freshness with every use.

The 'Nama PDRN-α Sheet Mask' is a daily sheet mask containing the highest-ever*6 amount of the key ingredients raw PDRN*1 and astaxanthin*3 in Yunth's history. It also contains 7D non-cross-linked hyaluronic acid*4 to condition the skin with intense moisture.

Bringing skincare inspired by aesthetic medicine into everyday habits, Yunth delivers a new experience for radiant, moisturized skin with raw PDRN*1 as its new key ingredient.
