Reveal smoother, brighter-looking skin with the K-SECRET SEOUL 1988 Retinal Liposome 2% + Black Ginseng Serum. This Korean skincare serum combines retinal in a liposome delivery system with black ginseng extract, niacinamide, bakuchiol, and peptides to support a refined, radiant-looking complexion.
Designed for skin concerned with visible signs of aging, uneven texture, and dullness, this lightweight serum helps improve the appearance of fine lines while supporting skin smoothness and a more even-looking tone. Make it a thoughtful addition to your evening skincare routine for nourished, healthy-looking skin.

Note: The 2% refers to the retinal liposome complex, not necessarily 2% pure retinal.
Daytime Tip: Apply broad-spectrum sunscreen with SPF 30 or higher every morning while using retinal products.
Individual results may vary depending on skin type, condition, and frequency of use. Retinal may cause dryness, redness, peeling, or irritation, particularly when first introduced. Perform a patch test before use and introduce the product gradually. Avoid combining it with other strong exfoliating or retinoid products until your skin has adjusted. Avoid contact with eyes and discontinue use if persistent irritation occurs. If pregnant, planning pregnancy, or breastfeeding, consult a healthcare professional before using products containing retinal. Store away from direct sunlight and keep out of reach of children.
