Apply a few drops to clean, dry skin in the evening, avoiding the eye and lip areas. Start by using 2–3 times per week, gradually increasing frequency as your skin builds tolerance. Always follow with a moisturiser to support hydration and barrier repair. Because AHAs increase sun sensitivity, apply a high-factor broad-spectrum sunscreen every morning. For best results, use consistently for at least 8–12 weeks as part of a structured exfoliation and brightening routine.
