retinyl palmitate
0.25% -
0.5%
Irritation risk:
Concentration: Insufficient!
Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect

Irritation risk:
Concentration: Effectiveness:
MEDIUM
A relative of vitamin E (Tocopherol). It can have an anti-oxidant effect in skin and/or to stabilize the product fromulation. It could be irritating but most of the reported allergy and irritation cases appeared in one geographic location (Switzerland) in 1992, and might be due to the quality issues in manufacturing of a particular batch of the ingredient

5.5% -
6.7%
Irritation risk:
Concentration: Effectiveness:
LOW
A more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.
