OS-01 Lip Mask delivers intensive overnight hydration with a rich, silky texture designed to leave lips feeling soft, smooth, and replenished by morning. Powered by the proprietary OS-01 Peptide™, the formula is developed to support key skin biomarkers associated with collagen, elastin, and hyaluronic acid for lips that appear firmer and more resilient over time.
The formula combines microalgae, ceramides, and squalane to reinforce the lips’ protective barrier and maintain lasting moisture. Astaxanthin, a potent antioxidant derived from algae, gives the balm its natural tint while helping lips look smoother and revitalised. Palmitoyl hexapeptide-12 works alongside OS-01 Peptide™ to support improved elasticity and overall lip condition.
Dermatologist tested, fragrance-free, and suitable for sensitive skin, the mask is formulated with vegan, sustainably sourced ingredients. It is free from parabens, sulfates, lanolin, MCI/MI, DEA, heavy metals, talc, petrolatum, mineral oil, gluten, phthalates, PFAs, and unnecessary additives. The refillable, compact design with custom applicator makes nightly use simple and precise.

Good, not perfect
I do like that this is safer for the environment. And it goes on just fine. Not greasy or anything. If you only use a little and rub well, your skin doesn't turn a ghostly white. Does great and I never have to reapply even after being outside sweating in heat and humidity all day. BUT, for some reason this is the only sunscreen I've ever used that has left a black ring around my finger where my wedding band sits. I've used a ton of sunscreens and I'm not sure why this one does it, but it's super annoying.

Does not work
This product does not work very well. Also does not rub in easy and takes several days to get it off of you.

Caribbean approved sunscreen
we bought this sunscreen due to the fact that the Caribbean doesn’t allow other sunscreens that are not Reef safe. I’m usually not a fan of mineral sunscreen due to the fact that it leaves a white residue. This sunscreen still leaves a white residue, but it is a very minor white residue. It worked well for the pool on our cruise ship and for the ocean. I didn’t have to reapply as often as I thought I would have for a mineral sunscreen. I don’t know if I still feel that the product was worth the price/amount, but I was overall satisfied with the Protection it gave us.
