Salicylic Acid 2% Masque is formulated to target lackluster tone & textural irregularities. The formula infused with charcoal & clays aims to enhance the appearance of smoothness & clarity leaving the skin feeling refreshed. The structure of salicylic acid facilitates its lipophilicity & miscibility with the lipids located on the surface of the skin. It is a suitable ingredient for targeting the removal of dead skin cells on the surface of oily & blemish-prone skin with the purpose of revealing more radiant skin beneath. Charcoal & clays are ingredients renowned for their deep cleansing abilities due to their porosity & large surface area available for adsorption. They aid the removal of facial impurities that would otherwise remain on the skin surface & clog pores. In comparison to Salicylic Acid 2% Solution Salicylic Acid 2% Masque is a rinse-off formula. Leave on for no longer than 10 minutes in order to maximize the exfoliating benefits. Contraindications: This formula should not be used on sensitive peeling or compromised skin. Please refer to additional sun protection note & other warnings in provided Directions. Note: While exfoliating acids can result in quick visible benefits we generally suggest the use of indirect forms of skin exfoliation in favour of direct forms such as this formula due to potential inflammation & sensitivity associated with acids. Please refer to NIOD's Non-Acid Acid Precursor for such a suggested formula.
