A face towel can be part of a regular cleansing routine, but it should not be presented as a way to prevent or treat acne. Whistle face towels are designed for everyday wet or dry use; they are not an acne treatment.
Acne has multiple causes and treatment differs from person to person. The American Academy of Dermatology advises people with acne to wash gently with a mild cleanser and apply it with their fingertips. It specifically cautions that scrubbing with washcloths, sponges and other tools can irritate skin.
Keep the routine straightforward
Use a cleanser or makeup remover according to its label directions. Rinse as directed, then use a towel only for the practical role you choose, such as patting away water. For any product, its label is the source for use frequency and ingredient directions. If acne is persistent, painful, scarring or concerning, consult a qualified dermatologist or healthcare professional.
