Tocopherol
Vitamin E
A naturally-occurring component of healthy skin, it offers significant antioxidant properties to help defend from pollution and other environmental stressors. It adds shine and smoothness to hair, seals in cuticle moisture, and helps with detangling, split ends, and frizz. It moisturizes skin and protects it from free radical damage.
Synthetic
Lab-made materials created to replicate the effect of a natural compound. Some synthetics are created in an effort to be sustainability-focused, while others are more efficacious, or provide different benefits than naturals.
