- JSJovita S.Verified ReviewerReviewingOS-01 LIP MASKI recommend this productRated 5 out of 5 stars5 hours agoMy go to night lip mask
I was actually a bit sceptical about this lip mask at first. The texture is a bit firmer than what I had used previously, and I wasn't using it consistently. My initial thought was, "I'll just finish it and probably won't buy it again," because I didn't notice much of a difference. Then I started using it every night (mostly because I wanted to finish it faster), and after about a week I realised my lips looked different in the morning. They felt noticeably plumper and much more hydrated. I also started to appreciate that once you go to sleep, you don't really feel the product on your lips, so your pillowcase stays free from lip mask stains!
Now that I'm almost out of it, I'm literally scraping every last bit from the jar, and I've realised this is the night lip mask for me. No irritating ingredients, no stains on my pillowcase, and the morning plumpness is amazing. I absolutely love lip products and I'm always trying new ones, but I don't think I'll be changing my night lip mask anymore. By the way, I understand that the included applicator is probably a more environmentally friendly option, but I just can't get used to it. I either apply the mask with my fingers or use the silicone applicator from another lip product. It might not bother everyone, but personally I think a silicone applicator would be a much better choice.

- VKV K. A.Verified ReviewerReviewingOS-01 LIP MASKI recommend this productRated 5 out of 5 stars1 week agoTHIS MASK IS THE BEST
I've had extremely dry lips for decades. I use the Lip Mask every night. What a difference! My lips aren't dry in the morning. In fact, they stay moist most of the day. This is the best product I've ever used.
- SKSara K.Verified BuyerReviewingOS-01 LIP MASKI recommend this productRated 5 out of 5 stars3 weeks agoBest lips ever
This is by far the best lip balm I have ever used. I love the applicator too!
- KBKassandra B.Verified BuyerReviewingOS-01 LIP MASKI recommend this productRated 5 out of 5 stars1 month agoOS Lip Mask
This lip mask is a must have I use it every night right before bed. I’ve been in the beauty industry for years and have never used a lip treatment that delivers such moisture.
