Bio-Collagen Real Deep Sheet Mask

The original, cult-favourite overnight collagen mask. This hydrogel mask is packed with ultra-low molecular weight collagen and probiotic ferments. It slowly melts into your skin over a few hours, turning from cloudy to clear as it absorbs, and leaves skin looking plumper, firmer and glassy-smooth.

Best for: Dull, dehydrated or tired skin, loss of firmness and pre-event prep. Suits all skin types.

Key ingredients

• Ultra-low molecular weight collagen: tiny collagen molecules for deep, bouncy hydration.
• Galactomyces ferment filtrate: supports a smooth, glowing complexion.
• Probiotic lactobacillus and bifida ferments: help calm skin and support a healthy barrier.
• Niacinamide and hyaluronic acid: brighten and lock in moisture.

How to use

As the last step of your evening routine, apply the lower half of the mask, then the upper half. Leave on for at least 3–4 hours, or overnight, until the mask turns clear. Remove and gently pat any leftover essence into your skin. Use once or twice a week.

Why BTY loves it

It's the mask that started the overnight hydrogel craze, and for good reason. Skin looks noticeably bouncier and more glowing the next morning.

Pairs well with

• Rejuvenating Caviar PDRN Real Deep Mask: a PDRN version for alternating nights
• Pore Perfecting Collagen Peptide Serum: hydrating serum before the mask
