Quintessence should be applied, using a cotton pad, to the affected areas twice a day. We suggest using it as a toner at night before bed, and then again in the morning after washing and before applying any make up or moisturisers. It must be applied to clean dry bare skin (without any other products applied to it).
Quintessence must be in direct contact with your skin to work effectively. Make up and moisturisers may be applied on top of Quintessence after waiting a few moments for it to thoroughly dry.
