Charcoal is deeply cleansing and works by absorbing excess oils and gently buffing and polishing the skin. Birch charcoal specifically is very fine and soft.
Birch trees are old inhabitants of the nordic countries. It is a pioneering species, growing in almost every type of soil. It can be identified by its recognisable black and silky white bark contrasting with its green foliage.
Birch charcoal powder is produced by the same local supplier as the charcoal Lush usually buys.
