Made for skin that's starting to show it
Fine lines, dullness, tired-looking skin, pores that didn't used to be there — this is exactly what an overnight collagen soak is for. Low-molecular collagen absorbs where thicker creams sit on top, so mature and dehydrated skin wakes up plumper, firmer-looking and rested. Gentle enough for sensitive skin, effective enough that you'll see it in the mirror on morning one.
What's inside — and why it works
- Low-molecular bio-collagen — a smaller collagen molecule designed to absorb deep into the skin instead of just sitting on top.
- Oligo-hyaluronic acid — draws moisture deep down and locks it in for that plump, dewy finish.
- Niacinamide — helps even skin tone and refine the look of pores overnight.
How to use
- Cleanse your face — apply to slightly damp skin for the best fit.
- Smooth the mask on before bed and leave it on overnight (or at least 2 hours). It's done when it turns from white to clear.
- Peel off, massage in the leftover essence. Glass skin.
Use 2–3 nights a week for best results.
FAQ
How often should I use it? 2–3 nights a week for best results.
What if the mask doesn't stick well? Apply to freshly cleansed, slightly damp skin and press gently around the contours of your face. A little slip is normal — it's the serum doing its job. Lying back for the first few minutes helps it settle.
How do I know when it's done? The mask goes on white and gradually turns transparent as the collagen and essence absorb. Clear = your skin has taken everything in.
Will it work on oily or acne-prone skin? Yes — it's lightweight and non-greasy, and niacinamide helps with oil and the look of pores.
Am I too old for this? The opposite — collagen production slows with age, which is exactly why mature skin sees the most visible difference in firmness and fine lines.
Can I use it with retinol or other actives? Use the mask on its own on mask nights, and your actives on other nights, to keep skin balanced.
How soon will I see results? Most people notice a dewier, plumper glow the very first morning; tone and pores improve with regular use.
Is it suitable for sensitive skin? Yes — it's fragrance-light and dermatologically friendly.

Woke up and my skin was actually glass. Bought 3 more for my sisters.
The peel-off is so satisfying and my pores genuinely look smaller.
Tried the viral ones. This is better and half the price. Repurchasing.
