Ilyang Low-Molecular Collagen + Hyaluronic Acid Sheet Mask, 7 Pack

Low-molecular collagen, sized to sink in

Collagen in its raw form is a very large molecule, far too big to move past the outermost layer of skin, which is why most collagen creams sit on top and rinse away. Ilyang's mask uses low-molecular (hydrolysed) collagen: the same protein broken into much smaller fragments that settle into the surface layers instead of beading on top. Paired with hyaluronic acid, a humectant that binds many times its weight in water, the 20-minute sheet format floods the skin with moisture and leaves it looking plump, smooth, and dewy. One box holds seven sheets, enough for a full week of nightly use or a twice-weekly month.

Why a sheet mask does what a serum can't

A serum absorbs in seconds and the rest evaporates. A sheet mask works differently: the soaked sheet forms a light occlusive seal that holds the essence against your skin for the full wear time, so the collagen and hyaluronic acid have twenty uninterrupted minutes to settle in rather than flashing off into the air. That extended contact time is the whole point of the format, and it is why a single sheet leaves skin visibly more hydrated than the same essence rubbed in by hand.

• Panthenol (Pro-Vitamin B5) — helps soften and condition the skin while supporting a comfortable moisture feel
• Centella asiatica extract — calming botanical widely used in K-beauty for soothing sensitive skin
• Allantoin — skin-soother that helps reduce the look of irritation

How to use

1. After cleansing and toning, unfold one sheet and lay it across the face
2. Smooth out air pockets so the sheet sits flush from forehead to chin
3. Leave on for 15 to 20 minutes; do not let it dry out fully on the skin
4. Remove the sheet and press the remaining essence in with your palms
5. Follow with moisturiser to seal the hydration; use in your evening routine
6. Apply SPF 50+ the next morning as part of your daytime routine

• Dull, dehydrated skin that feels tight straight after cleansing

Frequently asked questions

What does "low-molecular collagen" actually mean?

Collagen in its raw form is a very large molecule, far too big to move past the outermost layer of skin, which is why ordinary collagen products mostly sit on the surface. Low-molecular collagen is the same protein hydrolysed into much smaller fragments. Those fragments settle into the surface layers and act as effective humectants, helping the skin look plumper and hold onto water rather than simply coating the top of it.

How often should I use the mask?

For a concentrated hydration push you can use one sheet every evening across the full seven-day box, which many people do before an event or after a stretch of dry, tired skin. For ongoing maintenance, two to three sheets a week is plenty and makes the box last about three to four weeks. There is no benefit to leaving a sheet on longer than 20 minutes; once it starts to dry it can draw moisture back out, so remove it on time.

Will this help with fine lines?

The fine, crepey texture that shows up across the cheeks and under the eyes when skin is dehydrated softens noticeably when the skin is well hydrated. Hyaluronic acid and low-molecular collagen work on exactly that kind of surface dryness, so skin looks smoother and more cushioned after use. This is a cosmetic, look-and-feel effect rather than a permanent change to deeper lines.

Can sensitive skin use it?

The formula centres on hydration rather than strong actives like acids or retinol, so it is gentle enough for most skin types. If your skin reacts easily, patch test on the jaw for a day before applying a full sheet, and avoid use on broken or irritated skin. Stop use if you notice redness or stinging that does not settle within a few minutes.
