Forest of the Borges Idebenone Serum

The headline claim comes from a 2005 study that ranked Idebenone's oxidative-stress protection against five popular antioxidants (Vitamin C, Vitamin E, CoQ10, Kinetin, and Alpha Lipoic Acid). This study found it performed strongly in their testing model.

A companion six-week clinical trial on 41 women with moderately photodamaged skin found a 1% Idebenone formula showed a 26% reduction in skin roughness and dryness, a 37% increase in hydration, a 29% reduction in fine-lines/wrinkles, and a 33% improvement in overall photodamage. One thing worth noting about this study is that there was no vehicle control so not all benefits can be pinned on idebenone alone.

Typical usage for this ingredient sits between 0.5-1% (both concentrations validated in clinical work).

On the safety side, Idebenone is well tolerated by most people. There are a handful of documented allergic contact dermatitis in individual users so be sure to patch test if you have sensitive or reactive skin.

On the emulsifier side, it keeps your formula smooth and well-mixed by playing peacekeeper for ingredients that don't naturally get along (like oil and water).

Because it has a C12 (lauric acid) fatty acid chain, this ingredient can potentially feed the Malassezia yeast that causes fungal acne. The Malassezia yeast prefers esters with C11-C24 fatty acids.

This ingredient is an ester of lauric acid and Polyglycerin-10.
