RHYOLITE EXFOLIATOR 500 is a natural exfoliant made from the lava rocks of Strombolian volcanoes. Rhyolite is a low density lava rich in silica (71%) that forms in the magma of Strombolian volcanoes. Extremely abrasive, rhyolite allows a tonic exfoliation. It is the ideal mineral for regenerating the skin and smoothing the epidermis without affecting the hydro-lipidic film. These exfoliants brings a touch of naturalness and minerals to your formulas. They exhibit a good abrasiveness and a good stability.
