Key Benefits
Basically, it's a treatment that happens to feel like a balm. Smooth OS-01 Lip Mask on before bed and let it do its thing while you sleep. Come morning, lips feel soft, smooth, and actually replenished, not just sitting under a layer of product. That's thanks to the proprietary OS-01 Peptide™, which supports the biomarkers behind collagen, elastin, and hyaluronic acid. Stick with it and lips start looking firmer, plumper, and bouncier the longer you use it.
Microalgae, ceramides, and squalane pitch in to strengthen the lip barrier and hold onto moisture all night long. Astaxanthin, an algae antioxidant that's doing more work than you'd expect, gives the balm its soft rosy tint and leaves lips looking smoother and more awake by morning. Palmitoyl hexapeptide-12 teams up with OS-01 Peptide™ to support elasticity, so lips feel firmer and healthier the more you use it.
It's dermatologist-tested, fragrance-free, and gentle enough even for sensitive skin. The formula's vegan, made with sustainably sourced ingredients, and leaves out parabens, sulfates, lanolin, MCI/MI, DEA, heavy metals, talc, petrolatum, mineral oil, gluten, phthalates, PFAs, and anything else your lips really don't need.

I’ve absolutely loved this lip mask. It genuinely works and provides long-lasting hydration, leaving my lips feeling soft and moisturised for hours. I use it every single day now, and it’s become a staple in my routine. Highly recommend!
I love all of the Oneskin range and this is a great addition
