This is the ONLY eye makeup remover that completely takes off stubborn (but highly effective!) Japanese waterproof mascara. No other remover even comes close, not Lancome Bifacil, Neutrogena Oil-Free, Shu Uemura Oil, nothing will make my Sana mascara budge. The Sana remover comes in a tube with a plastic comb wand which you dip and apply just like mascara, except the tube has an oil-based remover. You comb through the underside and on top of your lashes, wait about 10 seconds, then gently wipe with a cotton pad, which I actually saturate with DHC Eyemakeup remover just to 100% remove everything. Voila! 100% clean! It is quite a process, but I love my Japanese mascaras so it's worth this cleansing ritual every night. Dept store mascaras just don't work on my straight spare short lashes, so this remover is essential since I will never stray from Sana!
