Extended data:

Matters needing attention in using clarins to extract essence;

This essence is divided into two pressing ports, a big drop and a small drop. Small drop mouth is suitable for oil skin or mixed dry skin, and large drop mouth is suitable for dry skin. Because the suitable water-oil ratio of the two skin types is different, there is a little difference in dosage, which is also the special feature of Clarins double extract.
