Is washing your face with bar soap good for your skin?

The effect of washing the face with soap on the skin depends on skin type and individual constitution. Soap typically has strong cleansing power, effectively removing oil and dirt from the skin surface. However, soap is generally alkaline and may disrupt the skin's natural pH balance, potentially damaging the skin barrier function. For individuals with dry or sensitive skin, using soap to wash the face may cause increased dryness, tightness, or even itching and peeling. In contrast, for people with oily skin, the cleansing power of soap might help reduce oil secretion, although excessive use could still damage the skin barrier.

It is recommended to choose a suitable facial cleanser based on your own skin type. If your skin tends to be dry or sensitive, opt for a gentle, non-irritating amino acid-based cleanser, which is usually weakly acidic and closer to the skin's natural pH level, effectively cleansing the skin while protecting the skin barrier. If you still prefer using soap, consider mild, low-alkaline soap specifically designed for sensitive skin, and apply moisturizing products promptly after washing to replenish lost moisture. When washing your face, it is recommended to use warm water and avoid excessively hot or cold water, as extreme temperatures may irritate the skin. Additionally, the frequency of face washing should not be too high—once in the morning and once at night is sufficient, as over-cleansing can compromise the skin's natural barrier.
