These include oligo-hyaluronic acid to deeply hydrate the skin, ultra-low molecular collagen to refine pores and smooth the skin and three different kinds of probiotics to strengthen the skin’s barrier and slow ageing for a glowing, moisturised and gorgeously smooth complexion.
In fact, after just one use, skin moisture has been seen to increase by 256 per cent, skin elasticity by 34 per cent and pore size decreased by 83 per cent.
For best results, the brand recommends using the two-part mask overnight as a sleeping mask, and thanks to its mess and residue-free application, many shoppers have been seen using the anti-aging mask on long-haul flights to keep skin looking radiant.
‘This is seriously such a nice luxury face mask experience,’ raved one five-star reviewer. ‘I wasn’t sure if it was gonna be gimmicky. I wore the first one around the house while I did chores. I looked a little bit crazy but afterwards my skin was so bouncy and juicy.’

Designed for even the most sensitive of skin, this hard-working mask has been credited as delivering impressive hydration without irritation or causing breakouts.
And users can’t get enough of it. Customer results show that 100 per cent agreed their pore condition and skin redness improved, while 95 per cent agreed their skin felt moisturised.
‘From the first application, I noticed an immediate difference in the texture and hydration of my skin,’ wrote another impressed reviewer. ‘The formula is lightweight yet deeply moisturising, making it perfect for my dry and sensitive skin.
‘What I love most is that it absorbs quickly without leaving any greasy residue, and it doesn’t cause any irritation or breakouts, which is often a concern with sensitive skin products. The fragrance-free aspect is also a huge plus for me since I tend to avoid strong scents.’

Another added: ‘Wow. I usually don’t take the time to write reviews. But I tried one of these for the first time last night and I’m amazed. Literally, down to every detail, these are exactly as described and as seen on social media, glass skin effect and everything.’
‘Totally worth the #1 best seller status for me! The mask is fantastic. The texture is so nice, it adheres to the skin unlike any other mask I have ever tried, the cooling effect is instant and it lasts the entire time you have the mask on. You can feel the tightening while it’s happening. My skin looks ridiculously good this morning!’ Another wrote.
