I recommend the collagen mask pack! I used to use Biodance mask packs, but the price was a bit too high for me. So, while browsing at Olive Young, I discovered that Abib also sells collagen mask packs. They come in hydration and soothing versions, but I prefer the hydration one! The ampoule doesn't fall off once you apply it, so it's less sticky, and it feels great to put on my face after a day of being in the sun. I highly recommend the Abib collagen mask pack!
