K-Secret · Step 4: Treat · Available in the Anti-Aging Glow Kit

The powerhouse of the kit: a next-generation retinal (retinaldehyde) serum, encapsulated in liposomes for a gentler, more stable delivery - paired with antioxidant-rich black ginseng. It earned its place in the Anti-Aging Glow Kit as the targeted step for fine lines, texture and tone.

How to use

PM only. After toner, apply 2-3 drops, then follow with moisturiser. Start 2 nights a week, then build up as your skin adjusts.

Yuri Glow Tip: Retinal is the one active to introduce slowly - start low and slow, and always wear SPF the next morning, as retinoids make skin more sun-sensitive.
