iS CLINICAL Active Serum FAQ

Can I use iS CLINICAL Active Serum every night? 

Why does iS CLINICAL Active Serum tingle?

A cool, invigorating tingling sensation is completely normal immediately after application. This reaction is caused by the active botanical extracts (like White Willow Bark and Sugarcane) working to deeply cleanse your pores and exfoliate dead surface cells. It typically subsides within a few minutes.

Can you layer Active Serum with Retinol?

It is generally recommended to alternate nights between iS CLINICAL Active Serum and Retinol rather than layering them directly on top of each other. Using both potent exfoliants at the exact same time can over-exfoliate your skin and compromise your moisture barrier.
