This treatment is a game-changer for oily, congested, and combination skin types. It is specifically engineered for those who struggle with "heavy" skin or visible oil production. For those with a more sensitive or dry profile, we suggest starting slowly—perhaps once every two days—to allow your skin to get used to the potent 15% concentration.

• Preparation: Start with a clean, dry face to ensure maximum penetration.
• Application: Use the dropper to apply 2 or 3 drops directly to the forehead and cheeks.
• Distribution: Use your ring fingers to gently spread the serum, focusing on the nose and chin where pores are most visible.
• Hydration: Follow up with a light moisturizer once the serum has fully settled.
• Sun Defense: If applied in the morning, always layer a high-protection SPF over the top.
