A rich emollient ester that softens skin and gives a smooth, cushiony glide, helping suspend pigments and filters. It adds a conditioned finish.

What does Isostearyl Isostearate do in skincare?

Isostearyl Isostearate is an ester used as an emollient and skin-conditioning agent. It gives products a rich, smooth, cushiony feel and helps soften the skin surface. It is also used to improve spreadability and the overall texture of creams and balms.

Is Isostearyl Isostearate comedogenic?

Isostearyl Isostearate is a rich fatty ester, and heavier emollients of this type are sometimes flagged as potentially pore-clogging for very acne-prone skin. Individual reactions vary and depend on how much is used and the rest of the formula. If you are highly breakout-prone, monitor how your skin responds.

Is Isostearyl Isostearate natural or synthetic?

It is synthetic in the sense that it is a manufactured ester, made by combining isostearyl alcohol with isostearic acid. The underlying fatty raw materials can be derived from plant or other sources, but the finished ester is produced through processing.
