Apply 2–3 pumps to clean, dry skin in the evening, avoiding the eye area. Leave on for 10–15 minutes before rinsing with lukewarm water. Use 1–2 times per week, or as recommended by your skincare professional. This stronger formulation is best suited for those already accustomed to enzyme exfoliation. Always follow with a moisturiser, and apply a high-factor broad-spectrum sunscreen during the day to protect against post-exfoliation sensitivity.
