How to Use

After cleansing and toning, apply 2–3 drops onto fingertips and press gently into slightly damp skin. Follow immediately with moisturizer to seal in the hydration. Use morning and/or evening.

When to Use

Morning and evening. Apply to damp skin for maximum absorption — the hyaluronic acid attracts moisture from the surrounding environment, so a slightly damp application maximizes its effect.
