BHA

What BHA is & what it does

Butylated hydroxyanisole, a synthetic antioxidant that protects a formula's oils from oxidation, extending shelf life. It safeguards the product, not the skin.

What does BHA do in skincare?

As listed on an INCI label, BHA refers to butylated hydroxyanisole, a synthetic antioxidant added to formulas to slow oxidation. It helps protect oils and other ingredients from going rancid, which extends the product's shelf life and keeps it stable. Note that in marketing the term BHA often means beta hydroxy acid such as salicylic acid, which is a different ingredient.

Is BHA safe?

Butylated hydroxyanisole is permitted as a preservative-type antioxidant in cosmetics and is used at very low levels. It is generally considered safe in that context, though some people prefer to avoid it. If you have concerns, a dermatologist can offer guidance based on your skin.

Is BHA natural or synthetic?

The antioxidant butylated hydroxyanisole listed as BHA is synthetic, produced industrially rather than extracted from a natural source. Because it is made synthetically, it generally contains no animal-derived material and is often suitable for vegan products.
