"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."

YOUR Favourite Beauty Products of the Year (According to You)

"This is OneSkin's OS-01 Peptide Lip Mask. I was so pleasantly surprised to see this on the list. It is superb. Not just a lip balm, this is a proper barrier repair product. I love the form factor and I love how it makes my lips feel. It's refillable."

The Obsession is Real (New Beauty Products)!

"Next up is the newbie by One Skin. It is their OS1 peptide lip mask. This has become my daytime essential. So, their OS1 peptide stimulates collagen, elastin, and hyaluronic acid production. And who doesn't need a little bit of that? [...] They say this is an overnight mask, but I use it throughout the day. Keeping my lips hydrated during the day is no small task, and with this, I find that I have to reapply it less than I do any other product."

"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."

"This is OneSkin OS-01 peptide for the lips, and what I've been doing is microneedling it into the lips every night. [...] I put a little bit on and then I'll take a microneedling tool. It's a very short one, not very deep, I'm sure it's a 0.25mm. And I microneedle this into my lips all along the lip line, in the meat of the lips, all of it. [...] I've been doing this now for two weeks, and the dehydration lines are gone. I wish I would have taken a before and after picture, but I didn't."

"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."

"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."

"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."
