Do leave-on benzoyl peroxide products present lower benzene risk than wash-off formulations? (Medscape AI)

In particular, Valisure’s petition data and subsequent investigations by the FDA and academic groups have shown that leave-on products often contain benzene concentrations below those detected in some wash-off cleansers. One proposed explanation is that leave-on formulations are typically manufactured in smaller batches, allowing faster cooling post-production and thereby limiting the thermal generation of benzene during processing1.
