I started to use the Mixed Berry mask sheet to give it a try. Here's a description of what it does:
For dull, dehydrated skin. Helps to even skin tone, brighten skin and tighten. They are suitable for all skin types.
The main ingredients are:
Mixed Berries (Blueberry, Raspberry, Mulberry...)
-> provides malnourized skin with the necessary vitamins from mixed berries
Green Tea extract
-> softens and effectively brighten your skin
I absolutely adore the berry sweet scent. I can feel my face instantly brightens after usage but I'm not so sure about the tightening effect, not so apparent in one use. My skin feels soft and did not break out the next day. Usually I will apply the mask for 30 minutes and in the mean time took a short nap with it.
The essence is just enough and it does not drip from the mask which is good. It also feels light on my skin and left no sticky feeling after I removed the mask. You can opt not to wash off the essence after application as it says so in the pack but usually I will just massage the essence into my skin before rinsing off with water.
I'm definitely repurchasing them because they are super affordable and I can see instant skin brightening effect after using it!
Note: Beware of fakes as they're really popular in Asia that there tends to be fake masks in the market.
