What it is & what it does
BHT is primarily an antioxidant for the formula itself.
WHAT IT IS: BHT (Butylated Hydroxytoluene) is primarily a formula antioxidant used to slow oxidation of oils and sensitive constituents in cosmetic products.
WHAT IT DOES / EVIDENCE: It can help maintain the stability and scent of an oil-containing formula during its expected shelf life. This role should not be confused with a clinically established anti-aging effect inside skin cells. The safety of BHT in cosmetics is assessed in the context of permitted concentrations and exposure.
IN THE FINISHED FORMULA: Its contribution is mostly product preservation and stability, rather than direct exfoliation, brightening or collagen signaling. The actual function depends on raw-material identity and product design.
