Triple Mud Clay Mask for Face — 23% Off

This clay mask combines three types of clay — typically kaolin, bentonite, and rhassoul or French green — for a more nuanced sebum-absorbing effect than single-clay masks. The format works well as a weekly oily-skin reset or as a targeted T-zone treatment between routines. Clay masks remain one of the most cost-effective single-purpose skincare products available. At $9.98 — 23% off the $12.99 list — this is a sensible add to a routine for anyone whose skin runs oily through summer.
