Detailed answer

An exfoliator should generally be left on the skin for approximately 1-2 minutes before rinsing it off. This time frame allows the active ingredients to work effectively without causing excessive irritation or sensitivity. Leaving it on for longer than recommended can potentially lead to over-exfoliation, which may damage the skin barrier and result in redness or dryness. It is essential to follow the instructions provided by the specific exfoliator product as some variations may require different application times.
