What the gurus are saying

The refillable system with applicator scoop and mirror draws consistent praise for thoughtful design. It absorbs quickly and stays comfortable for overnight wear, doubling as effective prep to help lipstick stay put. The proprietary peptide blend (OS-01) and ingredients like microalgae, ceramides, and squalane offer substance for those seeking potent actives, though it's positioned at a premium price point.

"I've been using the OneSkin OS-01 Lip Sleep Mask for ages. When I'm applying, I take it slightly outside of the lip line because those pesky vertical lines are starting to show themselves."

"This is an OS-01 peptide for your lips. It helps to get rid of zombie cells on your lips, dry, flaky lips. Like, this is a game changer. Sometimes I'll even microneedle this a little bit into the lip line. And then I like this just because it keeps them super hydrated."

"One Skin makes a peptide for the lips that I love. This is an OS1 lip peptide and it's amazing. It comes in a little case and I use it every single night, helping with those zombie, senescent cells."

"This One Skin lip mask is expensive, One Skin is a pricey brand with their proprietary peptide, but I do like this system. It's refillable and it comes with a little scoop to scoop the product out, plus a mirror, which is genuinely helpful. It's quite possibly the smartest design I've seen for a lip balm. The ingredients include microalgae, green algae, chlorophyll, ceramides, squalane, palm oil, hexapeptide, and their OS-01 proprietary peptide. It has a balmy consistency, I thought it would feel heavier from the appearance since it looks like honey, but it's not super heavy, and it will absolutely be comfortable for nighttime use."
Yay
"I always have my OneSkin lip with me, I am always carrying lip products because my lips get so dry here in Colorado. I always have one or two of these floating around, and these are my absolute two favorite lip products for keeping my lips soft and flaky free."

"This is a great new lip balm and it has their proprietary peptides, the OneSkin peptides, and it's a sleep mask. And it's so cute. I love the component. And it's refillable. So you can just pop out the component when you're done, and you just buy the refill. That's one thing I love about OneSkin. They are so conscious about doing refills."

"This is the OneSkin OS-01 Lip Sleep Mask. I love it. I like to prep my lips before I do my makeup so that my lipstick stays on better. And I've been hydrating my lips with this mask. And it comes with this cute little applicator. It opens up into this beautiful lip mask with their proprietary peptide blend. You just take a little bit of it, put it on your lips, and you're ready to go. Usually, it just sinks right in. By the time I'm ready to blot it off before I put my lipstick on, it's absolutely sunk in."
