Andalou Pumpkin Honey Glycolic Mask: How Long Should You Leave It On?
Andalou gives an upper limit of 20 minutes on clean skin, followed by a rinse. Set a timer as a reminder. You can wash it off earlier, especially if the mask feels uncomfortable.

Plan the rinse before you apply
Keep water and a clean towel within reach. Spread the mask evenly over clean skin. Start timing as you apply so you know how long it has been in contact with your face. When you rinse, let the water loosen the product instead of scrubbing for extra exfoliation.
How often does the label suggest?
The US directions give a range of one to three uses per week depending on sensitivity. The low end leaves time between applications to see how your skin responds. If it starts to burn, rinse it off promptly rather than waiting for the timer.
Read the sun-exposure note
The formula contains glycolic acid, an AHA. Andalou’s sunburn alert advises sunscreen, protective clothing and limiting sun exposure during use and for a week afterward. Read the alert on your own package when planning where this mask fits in your week.
