Laureth-4
May cause Acne
Some ingredients have a higher likelihood of clogging pores or triggering breakouts, especially for acne-prone skin. However, skin reactions are individual - what causes breakouts for one person may work fine for another. Patch test if you're concerned.
Explained
Laureth-4 is created by reacting ethylene oxide with Lauryl Alcohol. It is a surfactant and emulsifier.
Surfactants reduce the surface tension of ingredients so they can mix better. Emulsifiers prevent ingredients such as oil and water from separating.
