L’Oreal Paris’ new mask promises glass skin with a hydrogel material that turns clear when its work is done – we test it
If you’ve opened social media in the past few months, you’ll have seen ‘glass skin’ everywhere. The K-beauty ideal of skin that looks smooth, bouncy and borderline reflective has gone from niche skincare goal to full-blown mainstream obsession. Sheet masks had their moment, but now it’s hydrogel masks that are getting all the attention, mostly because they cling better, drip less and promise speedier results.
Enter L’Oréal Paris’ new Glass Skin Hydrogel Glow Mask, £11.99 for four (£3 per mask), which claims to deliver a dewy, plumped finish in 90 minutes. Inspired by Korean beauty routines and designed to turn transparent as it works, I was desperate to give it a try. Having tested dozens and dozens of hydrogel masks during my decade-long career as a beauty editor, I’m rarely won over by a mask – but I had a good feeling about this…
What makes this one different
This isn’t a quick 15-minute mask you squeeze in while scrolling. It feels like an proper skincare step. It comes in two pieces, bottom half first, then the top, and you leave it on until the hydrogel turns clear (around 90 minutes). That’s the cue that the ingredients have done their job. It looks faintly futuristic, but it also means you’re not guessing when to take it off.
The formula is built around a powerhouse trio: hyaluronic acid for hydration and plumping, glycerin to help lock moisture in and adenosine to smooth the look of skin. No actives that risk damaging your skin barrier, no sting, no drips or mess.

The 90-minute test
I tried this on a Sunday evening, which was a good moment for a mask that asks for a bit of time commitment. The first win was how well it stayed put. I answered emails, made tea and watched TV without it sliding down my face or folding into my hairline, which already puts it ahead of most sheet masks I’ve tried.
When I took it off, my skin looked noticeably better. Brighter, smoother, more even and, crucially, properly hydrated. My cheeks had that slightly springy, well-rested look, and the dullness that had been hanging around all week had packed up and left. The glow looked clean rather than shiny, which is the line many masks fail to walk.
I also really loved how my skin didn’t feel sticky, coated or overloaded, and I didn’t need to wait around before going in with my night cream. The next morning, my makeup sat better, which is usually the easiest way to tell whether a mask has earned its place in the cupboard, since most have effects that only last the day of application.
Is it worth adding to your routine?
Absolutely. If your goal is instant hydration, yes. I’ve tested masks five times the price of one of these L’Oreal sheets, and they’ve left me disappointed. For the price and how it delivers on its promises, definitely give it a go if you want your skin to look its best. I’ve also seen a fair few people using it on flights to stop cabin-related dehydration, and I love the idea of this.
I do think it’s up there with some of the best hydrogel masks I’ve tried in recent years, but if you’re shopping around, the next buy that I’ve lined up to test is Medicube’s PDRN Pink Collagen Gel Mask Pack, now £12.30 for a pack of four. I’ve seen them everywhere on social media, and people have been raving about how bouncy the mask makes their skin look. Packed with niacinamide and hydrolised collagen, it might give L’Oreal a run for its money…
