    Ferulic acid. Combination of AA + mixed tocopherols + Ferulic acid is very famous due to L’oreal Skinceuticals patent Note that they replace a lot of water with Ethoxydiglycol. The actual problem of AA oxidation is water, so if you make a waterless solution (e.g. Propanediol 90% + 10% AA) you won’t have as much oxidation as in water.

      BUT! I should mention that the study you provided is poorly designed. Only 12 females (almost like Garnier’s 9 out of 10 women on the jar), not statistically significant. Also, the study is blinded for the participants, but not double-blinded, the conductors know which area is treated with which product (or placebo). So I would not trust it.

      Unfortunately, there are not reliable (with proper design: double- or triple-blinded, correct placebo, done on statistically relevant set of humans - different ages, genders, races, correct number of participants) studies of AA out there.
