BHT · Butylated HydroxytolueneAntioxidant
A synthetic antioxidant used in tiny amounts to stop the oils in a formula from going rancid — it protects the product, not the skin.
What it does
BHT is a long-established antioxidant added at very low levels to keep oils and other oxidation-prone ingredients from spoiling on the shelf. Think of it as a preservative for the formula's fats. While it is an antioxidant, its role here is product stability rather than a skin benefit, and the amounts used are minute.
