How to Use

After cleansing and toning, apply 2–3 drops onto fingertips and press gently into skin. Allow to absorb fully before layering other serums or moisturizer. Start with once daily (evening), then increase to twice daily as skin tolerates. Always follow with SPF in the morning.

When to Use

Morning and/or evening. When starting out, begin with evening use only to assess tolerance. Most users see visible results within 4–6 weeks of consistent daily use.
