none i think because i never had a negative effect

So far i dont have a negative say to this product

I love all the sheet masks of Esfolio and this is not an exception. The scent is not overpowering and the material of the sheet mask is very nice as well. It fits really nice with my face and the essence is easily absorbed by the skin. After using, I can immediately see an instant glow and I hope that with continued usage, I will see more permanent effects.

I dont have ang negative effect of this product

Im inlove to this product. A must have for me
