Can I use Tocopherol with Tris(Tetramethylhydroxypiperidinol) Citrate?
Works well together
Tocopherol and Tris(Tetramethylhydroxypiperidinol) Citrate 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.
- ✓A hindered amine light stabilizer (HALS) based on the tetramethylhydroxypiperidinol (TEMPO-related) scaffold — used specifically to protect retinol from UV-induced and oxidative photodegradation in cosmetic formulations
- ✓HALS compounds interrupt radical chain reactions by scavenging peroxy and alkoxy radicals that initiate retinol degradation — without the HALS, retinol products lose potency rapidly under light exposure
- ✓As a citrate salt, it is compatible with aqueous formulation matrices; provides significantly improved retinol shelf-life stability compared to tocopherol-only antioxidant systems
