Ingredients

Refer to the product packaging for the complete and most current ingredient list. The manufacturer may update the formula without notice.

How to Use

Apply 2–3 drops after cleansing and toning, before heavier serums and moisturizer. Gently press into skin and allow to absorb. Start with evening use only (3x per week), gradually increasing frequency. Always follow with SPF in the morning — Vitamin C increases photosensitivity.

When to Use

Evening preferred, especially when starting out. Can be used in the morning once skin is accustomed, always followed by SPF50+. Introduce slowly — 3x per week for the first 2 weeks.
