Retinol Serum

The serum combines two types of retinol (1% retinol & 0.5% granactive retinoid) with squalane. This pairing is an intelligent one: since retinoids can dry the skin, the quenching squalane adds much-needed moisture to the party. It's like a time machine for how well it softens fine lines and takes years off your face. Apply on cleansed face and neck after water-based serums but before heavier treatments. Do not use along with vitamin C or exfoliating products. If you are new to retinoids, use 1-2 times a week at first and then slowly increase frequency.
