Face washes are designed to remove impurities, germs, dirt and makeup that can irritate the skin. Here's the tough part: when skin is cleansed too frequently, in contact with water or subject to harsh soaps, your skin's natural moisture is stripped—leaving it vulnerable to dryness and irritation. It helps remove dirt, pollutants, and grime that water cannot sweep alone. A good face wash also regulates excess sebum production in the skin. That's why skin care experts recommend using face wash for morning and night care routines (or AM and PM routines) to remove dust and grime in a hassle-free manner..
