It works on the look of volume. Most of us read our own face as lines, but what registers first is volume: lips look thinner, cheeks flatter, under-eyes hollow rather than simply tired.

5% Volufiline is the active aimed at exactly that. It sits in the stick with PDRN, collagen and NAD.

Under-eyes, forehead, smile lines, cheeks, lips and neck. It is a face and body balm, so it works anywhere skin looks dry or crepey.

Warm the balm against your skin for a second, then glide it on. Press it in with a fingertip if you like. You do not need a mirror and the whole thing takes about 10 seconds. Use it morning, night, or as a top-up during the day.

Less than you would think. One or 2 passes over each area is plenty. It is a balm rather than a cream, so it goes further than it looks.

Hydration and a softer, dewier finish show up straight away. For the look of volume and fine lines, give it 4 weeks of daily use.

The under-eye area is where most people use it first. Keep it below the lash line, off the lid margin, and out of the eye itself. If your eyes run sensitive, patch test on your inner arm for 24 hours before you take it near your face.

It is the ingredient this Korean category is built on, used in formulations for skin that looks renewed rather than tired.

It is also why the balm is pink and why the range carries the name.

Volufiline is the volume active, and 5% is the concentration these formulations use. It is the one thing in the stick aimed at areas that look hollow rather than lined. That is what separates it from a hydrating stick.

Last, or close to it. Cleanse, tone and serum as you already do, then glide the balm on. At night it can be your final step. In the morning it goes on before SPF.

On under-eyes and smile lines daily, expect roughly 1 to 2 months. Adding the neck and body will shorten that.

No. Women past 40 buy it most, because that is when lost volume starts to read on the face, but there is nothing in it a younger skin cannot use.
