Lip Plump - Refresh AHA BHA Vitamin C Lip Plumper

COSRX Lip Plump is a glossy lip plumper built around Volufiline, vitamin C derivatives and a pair of gentle acids. It arrives as a jelly-like gel cream that you scoop up and melt onto the lips, finishing with a wet, glassy shine. Expect a tingle — that's the plumping effect at work, not a fault.

What it actually does

• Volumises, per COSRX. The brand attributes the fuller look to Volufiline paired with vitamin derivatives, and describes the result as lips that look plump and energised.
• Sweeps away flakes. The AHA and BHA in the formula lift dead surface cells off the lips, which is why the finish reads smoother rather than patchy.
• Vitamin C derivatives for condition. COSRX credits these, alongside Volufiline, with supporting the health and vitality of the lips.
• Melts on contact. The jelly-style gel cream is firm enough to scoop but softens with the warmth of the lips, settling into a glossy water-glow layer.
• Tingles on purpose. The sensation comes from Vanillyl Butyl Ether and is normal for this category. How strong it feels varies from person to person.
• Works as a standalone or a topper. Because it is clear and glossy, it goes on bare lips or over a liner or lipstick.

How to use

1. Scoop a sensible amount. Pick up a small quantity of the gel cream — it spreads further than it looks like it will.
2. Spread it over the lips. Let the warmth of your lips thin it out into an even glossy film.
3. Let the tingle pass. A tingling or slightly uncomfortable feeling is expected here; it settles. If your lips are cracked, it will feel sharper.
4. Reapply through the day. COSRX positions it as both a daytime and a night-time step, so top up whenever the shine fades.

Questions

Why do my lips tingle?

COSRX names Vanillyl Butyl Ether as the cause, and says the tingling or mildly uncomfortable sensation is a normal part of the plumping effect. Intensity depends on the state your lips are in that day.

Is the plumping permanent?

No. This is a cosmetic plumper — the fuller look is tied to wearing the product, so reapply when you want the effect back.

Can I use it at night?

Yes. The brand describes it as volumising lip care for day and night, so it can sit on the lips as your last evening step.

Does it sit over lipstick?

It's a clear gel cream with a glossy finish, so a thin layer on top of a lip colour works. It will soften a matte formula underneath.

How long does delivery take?

Delivery takes 3 to 21 working days, depending on availability. In-stock pieces arrive early in that range; anything we source for you takes longer.
