Korean Volufiline Collagen Serum

Most serums only hydrate the surface of your skin, that's why they don't fix volume loss. This serum contains Volufiline, a clinical-studied ingredient that works at the fat cell level to restore volume in hollow areas.

100% Natural Ingredients 🌱

• Ultra-Low Molecular French Collagen (< 300 Daltons)

Penetrates deeply for up to 90% absorption, improving elasticity, firmness and skin density from within.

• Volufiline (Anemarrhena Asphodeloides Root Extract)

Clinically proven to deliver a filler-like plumping effect, smoothing fine lines and restoring youthful volume.

• Niacinamide (Vitamin B3)

Brightens dull skin, refines texture and balances tone for a healthy, even glow.

Free from Parabens, Sulfates, & Phthalates

How quickly will i see results?

You'll feel immediate hydration and plumpness within minutes. Visible improvements in hollow areas, fine lines, and firmness typically appear within 2-4 weeks of consistent use. The most dramatic transformation happens around 6-8 weeks as collagen rebuilding accumulates.

How is this different from regular collagen creams?

Most collagen creams use large molecules that sit on the surface. Our ultra-low molecular collagen (<300Da) is small enough to actually penetrate your skin barrier and rebuild structure from within. Plus, the 5% Volufiline stimulates your skin's own fat cells—something surface creams cannot do.

Can I use this if I've had filler or botox?

Yes. This serum works naturally with your skin and won't interfere with injectable treatments. Many women use it to extend their filler results or transition away from injections entirely

Can I use this on my neck and décolletage?

Absolutely. These areas show aging just as much as your face and benefit equally from volume restoration and collagen rebuilding.

Can I use this with my retinol/vitamin c/acids?

Yes. Apply after your active treatments (retinol, acids, vitamin C) but before your moisturizer. The gentle formula won't interfere with other products and actually helps buffer potential irritation from stronger actives.

Will this make me break out?

The non-comedogenic formula is designed not to clog pores.
