I have tried many lip's exfoliate and this is one of my most favorite so far. I take about 1 pump out and use finger to apply a layer over both of my lips. After ~5 minutes, a thick foam or bubble appeared. Then I used my finger to gently remove all dead lip skin, which has been soften by the foam. After that I wash my lips with lukewarm water and wipe with tissue. I am very satisfied with this product since it made my lips feel very soft and a little pink. Would love to buy again once empty whole bottle, I guess it might need several months.
