Grind a small piece of the Nila rock into a fine powder before use. Then mix it with rose water, yogurt, or a little argan oil until it forms a smooth paste, apply a thin layer to clean skin, leave it on briefly, then rinse well with lukewarm water. Current product sources commonly describe Nila as a traditional Moroccan hammam ingredient used this way rather than rubbed on the skin as a whole rock.

Use it gently and not too often. One recent guide suggests leaving facial use for about 5–8 minutes and using it 1–2 times weekly, while other current body-use sources describe leaving it on a little longer for body care. Avoid the eye area and patch test first, especially if your skin is sensitive.
