Ultra Repair Cream

A small humectant that attracts and holds water in the stratum corneum, delivered into the epidermis partly via aquaporin-3. It raises hydration, improves plasticity and desquamation, and supports barrier recovery — one of the best-evidenced moisturizing agents.

As listed: Ceramide NP

Sphingolipids that make up roughly 50% of stratum corneum lipids by mass (with ~25% cholesterol and ~15% free fatty acids) and organize into the lamellar bilayers that form the permeability barrier. Reinforcing them lowers water loss; deficiencies are a hallmark of atopic dermatitis.

A fully saturated emollient made by hydrogenating squalene (a natural sebum lipid), which makes it highly stable and non-comedogenic. It softens skin, reduces water loss, and penetrates efficiently without an oily feel.

A urea derivative that is keratolytic — helping shed excess keratin and smooth skin — while soothing irritation and promoting wound healing by stimulating cell proliferation and extracellular-matrix synthesis.
