I already use the Enzyme-Active Retinol Serum. If I’m supposed to use Water Lock on damp skin, how can I combine it with the Retinol Serum?Updated a year ago

Applying Water Lock directly to cleansed, damp skin is an emergency remedy for dehydration and isn’t necessary when your skin is in good shape. 

For maximum retinal efficacy, apply Retinol Serum to damp or saturated skin. This should be sufficient for maintaining your skin’s baseline hydration. Allow it to sink in completely, waiting for up to 30 minutes. Finally, apply a generous layer of Water Lock.
