    My lips feel so moisturized every morning. It is definitely part of my nightly routine that I will not stop doing. I place my mouth tape over it every night and it feels great!

    Not worth it

    I really wanted to love this but have my lips more dry and cracked than before using

    I will stick with less expensive drugstore options

    Hi Kerry!

    Thank you so much for taking the time to share your honest feedback about OS-01 LIP MASK — we genuinely appreciate it, and we're really sorry to hear that it left your lips feeling more dry and cracked than before. That's absolutely not the result we want for our customers, and we completely understand your frustration.

    We want you to know that your experience is concerning to us because OS-01 LIP MASK was specifically formulated to provide deep overnight hydration and repair for lips. The fact that it had the opposite effect suggests something may not have been right with your specific experience, whether it's an individual sensitivity, application method, or potentially even a product quality issue.

    A couple of things that might be helpful to consider: some customers find that if they apply too thick of a layer initially, it can sometimes cause an adjustment period where lips feel different for the first few uses. Also, because OS-01 LIP MASK is designed as an intensive overnight treatment rather than a daily lip balm, the formulation is quite different from typical drugstore lip products — and sometimes that difference doesn't work well for everyone's individual lip chemistry.

    Your feedback about the product making your lips more dry is really valuable to us as we continue refining our lip care line. We'd love to connect with you personally to understand more about your experience and see how we can make this right for you. Please feel free to reach out to support@oneskin.co so we can help!

    Thank you for giving OneSkin a try, Kerry. We truly appreciate your feedback and want to make sure you find a lip care solution that works well for you.

    Feels good on lips

    Feels good on my lips. Hard to tell if it moisturizes any better than the lip balm I was using before this, but it’s definitely not any worse. I like the little metal applicator because it feels fancy and feels nice on my lips lol. Like many others have said, the container is tricky to open.

    Great Mask

    Very hydrating. I love a sticky lip product as it stays put on my lips. I hope this product is refillable as I don’t need a new mirror every time I purchase.
