For very dry cold air, you want both ceramides and shea butter

The answer isn’t either/or — it’s both. Very dry, cold air needs a moisturizer that does two things: puts back what the environment stripped out, and locks it in so it doesn’t immediately evaporate.

Ceramides are the repair crew. Your skin barrier is made of ceramides, and when the air is dry and cold, those get depleted. Adding them back helps your skin hold its own moisture. Shea butter is the bouncer — it’s thick, occlusive, and physically prevents water from escaping. Ceramides without something occlusive will let that moisture disappear into the dry air. Shea butter without ceramides will just sit on top of a damaged barrier, doing surface-level work.

Look for a cream that lists both. Or layer: a ceramide serum or lotion first, then shea butter-based balm on top. Most dermatologists recs for winter skin are exactly this combo.

One note: if your skin is truly cracked or painful, skip fragrance and essential oils. Pure shea butter is fine, but scented shea butter can sting.

Don’t decide. Get both.
