    I bought this item hoping that I can stop having pimples on my chin x.x (seriously, I’m so done with having them.) And I’m definitely seeing results as I stopped having pimples popping up. I don’t know how long this will go, but I’m so so so glad to have found this product for now!!!

  2. Agnes Park

    It’s excellent for soothing skin and great to use when wearing a mask & it’s so nice to have my skin hydrated. It became a must-have item when wearing a mask.

  3. Michaela

    My face is a bit small, so I can see it sticking out a little bit over the mask, but I like how it calms my skin. It’s definitely cooling and my face doesn’t feel hot even when I wear the mask for a long time. But the best is that it prevents the masks touching my face skin!

    This is a skin-saver for when you work out! I wore this when I went for a hike with my mom and usually we complain about how hot it gets inside of masks. However, for this time, it didn’t!!! Undermask was actually super cooling and made our faces not heated up even when we were having heavy breaths and sweating. Super amazing XD

    Overall a good mask to go with your protective masks. It would’ve been great if they were multiple use.

    lifesaver for when you workout.

    Perfect for the times you have to wear masks in hot weather! I feel like I should buy more for the upcoming Summer 😅

    It leaves this lovely feeling of being refreshed and cooled down even after you take it off. Truly amazing <3

    I use it as a regular mask after the long days. It feels like a little treat. Super cooling and refreshing.

    The essential for when you go out around this time of the year. I know a lot of people are not wearing their masks anymore, but I still do when I get out even though I am fully vaccinated. I used to worry getting pimples and breaking out because of the mask but with undermask, I can stay safe without worrying about breakouts.
