How Often Should You Perform Ruqyah?

Salaam everyone! I’ve been dealing with acne and tried ruqyah once or twice about a week ago. Alhamdulillah, not only did my skin start looking better, but I also felt this unexpected peace about my acne, MashaAllah. The constant urge to check my face in the mirror and the impatience just faded, Alhamdulillah. Since I’ve only done it a couple times, I’m wondering: how many days in a row or how often should I continue with ruqyah?
