For your skin
A lab-engineered version of CoQ10 that gets deeper into skin cells. Modest visible improvements over months. Comparison studies place it below vitamin-C-plus-ferulic combos, but it's useful when C is poorly tolerated.

Synthetic CoQ10 analog with a shorter side chain that crosses the lipid bilayer more readily; quenches mitochondrial superoxide and reduces lipid peroxidation in photodamaged skin.
Why we tier this moderate
5 cited papers across 4 countries. The mechanism is well-described and there's at least one controlled trial in the literature, but we tier this Moderate rather than Strong to stay honest about how many specific papers we cite directly.
