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.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it.
The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.
