Some serums promise results. This one delivers them.
The KSECRET Seoul 1988 Retinal Liposome 2% + Black Ginseng Serum is one of the most powerful Korean anti-aging serums available today. Inspired by Seoul’s legendary skincare heritage dating back to 1988, this formula combines two of the most clinically proven ingredients in modern dermatology — Retinal and Black Ginseng — into one lightweight, fast-absorbing serum.
Whether you are dealing with fine lines, wrinkles, uneven skin tone, dark spots, dullness, or loss of firmness — this serum targets all of it in one step.
What Makes This Serum Special?
Retinal Liposome 2% — Next Level Vitamin A
Most people know Retinol. But Retinal (Retinaldehyde) is the upgraded version.
Retinal is one step closer to Retinoic Acid than Retinol — meaning it works up to 11 times faster while being gentler on the skin. The Liposome delivery system encapsulates the Retinal in tiny bubbles that penetrate deep into the skin layers and release the ingredient slowly. This means:
- Maximum effectiveness deep inside the skin
- Minimum irritation on the surface
- No redness or peeling that traditional retinol can cause
- Safe for even sensitive skin types
Black Ginseng — Korea’s Most Powerful Anti-Aging Root
Regular ginseng is already powerful. Black Ginseng is ginseng that has been steamed and dried nine times — a traditional Korean process that dramatically increases its potency and bioavailability.
Black Ginseng contains:
- Rare ginsenosides that stimulate collagen production
- Powerful antioxidants that fight free radical damage
- Natural compounds that improve skin elasticity
- Anti-inflammatory properties that calm and soothe skin
The combination of Retinal + Black Ginseng creates a dual-action anti-aging formula that works on both the surface and deep layers of your skin simultaneously.
Key Benefits
Visibly Reduces Wrinkles and Fine Lines Retinal 2% stimulates collagen production and speeds up cell turnover — smoothing out fine lines and deep wrinkles faster than standard retinol products.
Brightens and Evens Skin Tone Black Ginseng inhibits melanin production and fades dark spots, hyperpigmentation, and post-acne marks — giving you a naturally brighter and more even complexion.
Firms and Tightens Skin The combination of Retinal and Ginseng ginsenosides boosts collagen and elastin — restoring firmness and reducing sagging for visibly tighter skin.
Deep Hydration Without Heaviness The Liposome technology delivers active ingredients deep into the skin while maintaining the skin barrier — keeping skin plump, hydrated, and healthy.
Radiant Glass Skin Glow Regular use gives skin the signature Korean glass skin look — clear, luminous, and naturally glowing from within.
Antioxidant Protection Black Ginseng is packed with powerful antioxidants that protect skin from environmental damage, pollution, UV stress, and premature aging.
