Can I use Arginine with Ornithine?
Works well together
Arginine and Ornithine are generally compatible and can be layered in the same routine. As always, introduce one new active at a time and watch how your skin responds.

- ✓Amino acid that acts as a skin-conditioning agent, contributing to surface smoothness and moisture balance in formulations
- ✓Participates in the natural moisturizing factor (NMF) pool of the stratum corneum, contributing to natural hydration maintenance
- ✓Metabolic precursor to proline and hydroxyproline (collagen amino acids) — in vitro evidence suggests ornithine supplementation may support collagen turnover in skin cells
