I've always enjoyed the service hyaluronic acid mask in my packages and finally decided to purchase some. They are 대박!! I got 3 of the snail and 3 of the teatree formulas. Although I have oily acne prone skin, I prefer the creamy snail mask over the traditional thin serum of the tea tree mask. The creamy ones feel more luxurious and leave my face looking more nourished. If you prefer a more cooling or soothing type of feeling from your sheet mask though, the tea mask is the to go!! Either way, they are great mask!!
