Use a clean fingertip or a soft brush to take a small amount of pigment from the clay pot, then apply it gently to the lips or cheeks and blend until you get the desired color. Aker Fassi is commonly sold as a traditional Moroccan lip and cheek tint in a terracotta clay pot.

Do not spray water directly on the clay pot.
If needed, lightly dampen your fingertip or brush instead of wetting the pot directly, then apply a small amount and build the color gradually.

Use only a little product each time, and keep the pot dry and closed after use.
