Gel left them paper thin.
Six weeks of keeping a coat on and the tips stopped peeling. They finally feel like nails again.

The Signature Pen · Keratin Protect
Glossy color and a keratin-enriched coat for thin, peeling nails. No lamp, no filing.
That is who we made it for. Each coat adds a keratin-enriched layer and seals the free edge, where thin nails peel and split.
No, and that is the point. No UV lamp, no filing, no long acetone soak to take it off.
With your usual nail polish remover. No soaking, no scraping.

How it works
Keratin is what nails are made of. Each coat lays it over the weak spots and seals the edge, where nails peel.
Six weeks, same hand



K-BEAUTY INNOVATION
In Korea, nail care is treated like skin care: color is expected to protect, not just decorate. The keratin-enriched formula behind The Signature Pen comes from that Korean innovation, now in a pen you can use at home.

I hold it like my pen and rest my wrist on the table. Clean line at the cuticle, and the splits have calmed down.

I keep a coat on and refresh it every few days. The corners stay intact now.
