Vitamin D in skincare is rarer than you’d think — and Dr. Dennis Gross‘s Active Vitamin D Serum-Oil is one of the few formulations that delivers it well.
What’s in it
A high-grade vitamin D complex in an oil-serum base, supported by antioxidants and barrier-restoring ceramides. Vitamin D plays a role in skin’s immune response and turnover — both decline with age, sun exposure, and stress.
How it wears
A few drops, pressed into clean skin at night. Absorbs without residue. Skin reads brighter and more resilient over weeks of consistent use.
The under-the-radar serum worth knowing about.
