For a boy the number of times he uses a face scrub in a week really depends on the skin type.( how many times scrub face in a week for boy). It’s important to listen to your skin and adjust your exfoliation routine accordingly. If you notice any redness, irritation, or discomfort after exfoliating, you may be scrubbing too frequently or using a scrub that is too harsh for your skin. In this case, it’s best to reduce the frequency of exfoliation or switch to a gentler exfoliant.
