    I use this when I go hiking. Super cooling and refreshing! This is an ESSENTIAL for hiking.

    It’s nice. If I wear a mask for a long time, my skin feels heated and I tend to get pimples on my cheeks and chins. Undermask definitely helps in this. Also, I kind of feel that it doesn’t make the inside of the mask stuffy… maybe because of the cooling effect? Anyhow, I’m going to keep buying it and using it. I feel like this is going to be necessary for the summer weather.

    It takes me about an hour to get to work and I use public transportations to commute. I use Undermask while commuting and have been loving it. It doesn’t get entirely covered by the mask, but I don’t really mind because it doesn’t look too bad. There are plenty of pros to balance out this tiny tiny con.

    Feels nice when I wear it under mask ~

  5. Christina Rhee

    I has saved my skin from getting obnoxious amount of acnes that I used to get from wearing masks. This will continually be a part of my regular skincare routine now. I think I may just use it even when I don’t wear masks.
