Removing makeup is as important as applying makeup.If not done properly can have serious effects on skin as it can cause allergies, acnes and pimples .So its a thumb rule to remove all makeup at night before sleeping.
One can use makeup removers to remove makeup.Makeup removers from various brands are available in the market like Maybelline Clean express makeup remover, which removes even water proof makeup without leaving any residue, it also removes eye makeup.Then we have Lotus Herbal cleansing milk which can be used to remove makeup, it also moisturizes the skin.
I have used Ayurs cleansing milk as makeup remover, its good, one needs to apply it on cotton balls and then remove all makeup with it including the eye makeup.
For a cleaner look one can even wash their face with a good face wash after using makeup remover, that really makes the skin clean and clear.
Another way is to use a good wet wipes which gently removes all makeup and does not irritates the skin.One can even use baby wipes for this .
So use a makeup remover, wet wipes and face wash from a good brand to remove all makeup before sleeping.
