Ask any make-up lover what the cardinal sin in the world of beauty is and they'll point out this one — not removing make-up from your face before hitting the sack. The disadvantages are more than just soiled pillowcases. Skincare expert Dr Aneesh Sheth says, "Leaving make-up on can clog pores, dry the skin, give allergies and make skin sensitive to the sun and other cosmetics." Make-up artist Clint Fernandes adds, "Let the skin breathe and be free from excessive layers, especially at night when it is resting.

Besides, leaving on eye make-up can cause clogging of the tear ducts and build-up of particles around the cornea and inside the eyes." Make-up artist Cherag Bambboat too warns, "If your skin has residue from the earlier make-up, the fresh coat that you apply has a higher chance of oxidising — not pretty, for sure."
