Can I use this mask on my face if I have combination skin that gets oily only in the T-zone?

Yes, this mask is suitable for oily and combination skin types. The key ingredient, kaolin, is a fine clay known for a gentler action than stronger drying clays. This makes it effective at lifting away oil and residue from the T-zone (forehead, nose, chin) without causing the heavy, tight feeling that can be uncomfortable or overly drying on the cheeks, which might be drier or more normal. To use it effectively, you can apply a thinner layer or focus the mask primarily on your oilier areas, leaving it on for the recommended time, then rinse thoroughly. For areas that are less oily, you might choose to apply it less frequently or for a shorter duration. The included sage and rosemary extracts help the skin feel cleaner and fresher, complementing the clay's absorbent action. It's wise not to let the mask over-dry, especially on more sensitive parts of your face. A patch test on a small area of your jawline is a sensible first step.
