ROUND LAB Silver Birch juice moisturizing mask sheet 10ea set

Ten sheets soaked in silver birch sap with amino acids, minerals and hyaluronic acid. Same format as the mugwort box, different brief: this one is a moisture charge rather than a calming step, and the sheet is the delivery method for essence you would otherwise have to layer four times to match.

Who it's for. Dehydrated skin, and skin that goes flat and rough in winter or under air conditioning.

How to use. Two to three times a week after toner. Apply, leave 15-20 minutes, remove and pat the leftover essence in. Always seal with moisturizer, because a sheet mask left to dry on the face pulls water back out.

Key active. Silver birch sap amino acids with hyaluronic acid, a humectant load intended for a dewy, plumped surface.

Sourced in Seoul. This is the Korean domestic SKU, not a reformulated export version.
