K-Secret Seoul 1988 Retinal Liposome 2% + Black Ginseng Serum (30ml)

♥ Cruelty-Free

The most concentrated retinal serum in your SAENG SKIN collection — and arguably one of the most impressively formulated retinal serums available in K-beauty at this price. Retinal is a fundamentally different molecule from retinol: it sits one step closer to the skin’s active form, meaning it works faster, more visibly and more effectively at the same concentration. This serum delivers 2% Retinal via a Liposome delivery system — encapsulated in lipid spheres that release it slowly and precisely through the night — paired with 58% Black Ginseng Extract, a rare form of Korean ginseng processed nine times for amplified antioxidant potency. The result is a dual-action formula that visibly tightens, firms and resurfaces while the ginseng’s concentrated richness restores radiance from within. Bakuchiol works alongside the retinal to further boost collagen production, while a stable form of Vitamin C, Niacinamide and three Growth Factors address texture, tone and firmness simultaneously. The most results-driven product in the Seoul 1988 range. Fragrance-Free. Paraben-Free

How to Use

In the evening only, after cleansing and toning, apply a pea-sized amount to clean, completely dry skin. Gently massage until fully absorbed. Follow with a plain moisturiser. Start with twice weekly in weeks 1–2, every other night in weeks 3–4, then nightly from week 5 onwards.

Actives Retinol and Retinal deliver real results — but they also increase UV sensitivity. Protect that progress every morning with SPF50+. Avoid use alongside exfoliating acids, high-strength Vitamin C or other retinal/retinol products.

Tip: The ‘sandwich method’ — applying a thin layer of plain moisturiser before and after the serum — provides an extra buffer for those new to retinal at this concentration, reducing any initial sensitivity without affecting results.
