This mask is most often chosen by people with combination or oily-looking skin, because the astringent tannins help the surface look more refined and less shiny after rinsing. The mild physical exfoliation also lifts surface buildup, which can make the skin look cleaner and more matte. If that sounds like your skin, once or twice a week is a good starting point.
If you have dry skin, you can still use it, but adjust the approach: mix with water instead of rose water for a lighter feel, keep the leave-on time shorter (5–10 minutes), and use it less often — once a week or every other week. The mask is not a moisturizer, so always follow with your regular moisturizer after rinsing.
For sensitive or reactive skin, the key is to start gently: a single application, a short leave-on time, and then observe how your skin feels over the next day. If you notice any redness or discomfort, stop using it. This is a concentrated treatment powder, not a daily cleanser, so it works best as a weekly addition to your routine rather than something you use every day.
