Start with clean, dry skin. Apply a thin, even layer to your face, avoiding the immediate eye area and lips. Do not rub or massage it in aggressively. Leave it on for the time specified in the product's instructions (if not provided, a common range is 3-10 minutes, but err on the shorter side for first use). It's normal to feel a slight tingling sensation. Do not leave it on for an extended period expecting better results, as this increases irritation risk. Rinse thoroughly with lukewarm water, ensuring all product residue is removed. Gently pat your skin dry with a clean towel. Follow immediately with a gentle, hydrating moisturizer to support your skin's barrier. Never use this product on broken, sunburned, or irritated skin.
