What precautions should I take?

Inform your healthcare professional if:

Avoid washing your face too often as this may increase the drying-out effect of your medication. Wash your face two to three times a day only.

Unless otherwise directed by your doctor, avoid using other “drying” preparations on the same treated areas to prevent severe irritations. These include harsh soaps and cleansers, alcoholic preparations and medicated cosmetics or soaps. 

Avoid staying directly under sunlight for long durations. Use a broad-spectrum sunscreen product with Sun Protection Factor (SPF) of at least 30 and wear protective clothing when you are exposed to direct sunlight.

Avoid applying heavy make-up and using oily cosmetics. It is recommended to choose make-up products with non-oily formulas.

Handling and storage
