Ceramide-rich barrier serum for tretinoin dryness; absorbs quickly, supports dehydrated skin.

A lightweight ceramide-and-panthenol serum with cholesterol and phytosphingosine for barrier support. It fits easily before moisturizer in tretinoin routines and helps dehydrated, reactive skin feel less stripped, though very dry skin may still feel tight without cream.
