K-SECRET Retinal Serum 2% Liposome + 58% Black Ginseng, 30ml — Nighttime Texture & Fine Line Treatment

K-SECRET SEOUL 1988 Retinal Serum is a concentrated nighttime serum that combines 2% retinal encapsulated in liposomes with 58% black ginseng extract to improve skin texture and reduce the appearance of fine lines.

This serum blends a next-generation retinal formula with an advanced liposome delivery system and a retinal-boosting complex to support smoother, more even-looking skin. Designed by K-SECRET, the lightweight 30ml pump offers targeted nighttime treatment: retinal works efficiently while liposomes enhance stability and absorption, and antioxidant-rich black ginseng supports skin resilience and radiance.

How does the retinal liposome delivery system improve results?

The liposome delivery method surrounds active retinal molecules with tiny carriers that protect them from degradation and help them penetrate the skin barrier more effectively. This improves ingredient stability and enables more retinal to reach the layers where it can contribute to visible texture improvements.

• 2% retinal encapsulated in liposomes for enhanced delivery
• Liposomes reduce oxidation and preserve potency
• Improved absorption for faster visible effects compared with non-encapsulated forms

What other actives are included and what do they do?

Besides retinal, the formula pairs 58% black ginseng extract with bakuchiol, three targeted peptides, and niacinamide to create a balanced retinal-boosting complex. These ingredients work together to support skin tone, refine pores, and maintain surface smoothness without relying on a single active.

• Black ginseng extract (58%) for antioxidant support and skin conditioning
• Bakuchiol provides complementary retinol-like activity with calming properties
• Peptides help support the skin’s overall texture and resilience
• Niacinamide assists with evenness and visible pore appearance

When and how should I introduce this serum into my routine?

This retinal serum is formulated primarily for nighttime use to avoid exposure to sunlight which can oxidize retinal. Begin slowly to build tolerance: start with twice-weekly applications for the first one to two weeks, then gradually increase frequency based on how your skin responds.

• Use at night after cleansing and toning, before moisturizer
• Apply a small amount over face and neck; massage until absorbed
• If used in daytime, always follow with broad-spectrum SPF
• Reduce frequency if irritation or sensitivity occurs; layer with hydrators

What can I expect in terms of texture, scent, and packaging?

The serum has a lightweight, fast-absorbing texture designed to layer under moisturizers without pilling. K-SECRET packages the 30ml product in a protective pump to limit air exposure and preserve the retinal-liposome complex. Fragrance is minimal to reduce potential irritation.

• Light serum texture that absorbs quickly
• Protective pump packaging to maintain stability
• Minimal scent formulation for sensitive-prone skin types

Who is this for: K-SECRET SEOUL 1988 Retinal Serum is best for adults seeking an advanced nighttime treatment to improve fine lines, visible texture, and uneven tone while using a scientifically supported delivery system. It's suitable for those familiar with retinoid-type products or anyone wanting a controlled introduction to retinal—people with very reactive skin should introduce it slowly and consult a skin professional if needed.
