Cleansing is the first and most important step of a routine. Throughout the day, oil, sweat, pollution and product residue build up on the skin. Gently removing this is essential for healthy-looking skin and for the next steps to work.
But "more is better" doesn't apply. Harsh, high-pH or heavily foaming cleansers can strain the barrier and strip natural lipids, causing dryness and sensitivity. The right choice is gentle, pH-balanced cleansers.
Twice-daily gentle cleansing suits most skin. Over-cleansing tires the barrier. Use lukewarm water, avoid very hot water, and pat dry gently. Consult a physician for a cleanser suited to your skin type.
