To prepare for a medical-grade facial, it is recommended that you avoid using harsh exfoliants, retinoids, or other strong skincare products for a few days before your appointment. It's also best to refrain from undergoing other facial treatments, like waxing or laser procedures, close to your appointment to prevent irritation. Make sure to inform your aesthetician of any medications you are taking or recent skin treatments you have had. Arriving with clean, makeup-free skin will allow the facial to be most effective.
