주름개선: the actives behind Korea's anti-wrinkle claims

For wrinkle-improvement claims Korea recognises a small set of actives — adenosine is the most widely used, alongside retinol and retinyl palmitate, and polyethoxylated retinamide. Adenosine's prevalence in Korean anti-ageing creams is a direct result of this system.

Why adenosine is everywhere

Adenosine is well tolerated, stable, and notified for wrinkle-improvement claims at a specific concentration. For a formulator that combination is close to ideal: a reviewable claim without the irritation and packaging headaches a retinoid brings. Hence its quiet presence in an enormous number of Korean creams.

Retinol in the Korean system

Retinol and retinyl palmitate are also recognised, at their own notified levels. Because retinoids are less stable and more irritating, Korean brands often pair them with soothing ingredients and opaque, air-restricting packaging.

What the claim actually covers

The claim concerns the appearance of wrinkles. It is a cosmetic claim about how skin looks, reviewed for evidence — not a medical claim about reversing skin ageing, and it should not be read as one.

Setting expectations

Notified actives are notified because there is evidence at that level, not because they work quickly. Wrinkle claims are typically assessed over months of consistent use, and that is the timeframe to judge yours on.
