Regimen's Take

Tocopherol is a 'family' of Vitamin E's produced in the body. The most active of these is alpha-Tocopherol. Similar to other antioxidants, it has strong free radical scavenging ability, but it also has higher pro-oxidant capacity, meaning that formulated poorly it can have the reverse effects and contribute to skin damage. It 'relaxes' when it reacts with ascorbic acid vitamin C, but with ferulic acid it stablilizes.

TLDR

As with any antioxidant, no single antioxidant can tackle the whole UV damage/ inflammation / etc. process - so it's best to look for Tocopherol (like any antioxidant) in combination with other antioxidants - specifically

The Skincare Encyclopedia aims to improve public understanding of the biology and chemistry of skincare. The Encyclopedia is rooted in core scientific principles and extensive research, in many cases in collaboration with the authors of the original studies referenced. This is a project of Regimen Lab, maintained by a group of multidisciplinary scientists, MDs, and researchers.
