Dermatologist-Tested.\u003c\/h2\u003e\u003cp\u003eK-SECRET Seoul 1988 Serum is a targeted K-beauty anti-ageing treatment that pairs two of skincare’s most potent actives in a single, fast-absorbing formula. Retinal — the aldehyde form of vitamin A, considered more effective than retinol at the same concentration — is delivered at 2% via liposome encapsulation for enhanced penetration and reduced irritation, working to refine skin texture, minimise wrinkles, and improve uneven tone. This is complemented by 58% black ginseng extract, a prized Korean botanical with potent antioxidant, anti-inflammatory, and collagen-boosting properties. Niacinamide, bakuchiol, and peptides round out the formula to enhance elasticity, brighten the complexion, and support long-term skin resilience.\u003c\/p\u003e\u003cp\u003eDermatologist-tested.
