While I have only used the lip mask for a short time, my lips seem more hydrated. I do enjoy this product and will continue to use it.

Lip SPF 15+ what a lovely lip treatment. This product is quite nourishing. The cooling metal applicator blends the creamy product as it melts into your lips.
Makes my lips very soft and supple.
I definitely recommend this lip treatment.

- JOJennifer O.Verified BuyerReviewingDAY + NIGHT LIP DUOI recommend this productRated 5 out of 5 stars23 hours agoThis really works!
Works great but the circular packaging is weird and unnecessary
OneSkin7 minutes agoHi Jennifer!
Thank you so much for this wonderful 5-star review and for letting us know that the DAY + NIGHT LIP DUO is really working for you — that's exactly what we love to hear!
We really appreciate your honest feedback about the circular packaging too! We know that the round format can feel a bit different from traditional lip product packaging, and we totally understand that it might seem unnecessary at first glance. The circular design was actually chosen to make the duo easy to grab and go while keeping both products securely together, but we definitely value hearing when customers find certain design elements less intuitive.
The most important thing is that you're getting those great results from the formula itself — the OS-01 LIP SHIELD SPF 15+ during the day and OS-01 LIP MASK at night work together to provide 24-hour cellular support for your lips, protecting against environmental damage while promoting overnight restoration.
Thank you for taking the time to share your experience and for encouraging others by letting them know it really works! Feedback like yours about both the performance and the packaging helps us continue to improve and helps other customers know what to expect.
We're so glad your lips are loving the results, Jennifer!
