Beeswax is a natural wax often used in natural cosmetics. It is however not safe for acne skins. Originally when comedogenic testing was done beeswax scored a ranking of 0-2 depending on who the supplier was.
Subsequent testing at a later stage showed that beeswax is much more comedogenic than previously thought. Beeswax should be avoided by those with acne prone skin.
You may also have to be careful of Chapsticks and lip balms as they also often contain beeswax. This can be a contributor to acne and blackheads along the lip line.
