Cleanse thoroughly and whilst the skin is still slightly damp, massage in 2-3 generous drops of the fragrance-free serum. Applying to damp skin enables the water-binding process of hydroscopy to take place more effectively to encourage complete hydration from sunrise to sunset. Use twice daily before oil-based formulas. 

Caution: For external use only. Avoid contact with eyes. Keep out of the reach of children. Do not store in direct sunlight.
