Isopropyl Myristate is a fast-spreading ester emollient and penetration-enhancing solvent.
It reduces roughness and gives a silky finish, while also helping some oil-soluble ingredients move through the outer skin more easily. Some acne-prone users find very rich formulas containing it less comfortable, so the whole formula matters.
Usage & cautions
Very acne-prone skin may prefer to patch test richer formulas containing high levels of Isopropyl Myristate.
Information approach
Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
