Topical rapamycin inhibits the mTOR pathway directly in skin cells, which is thought to reduce cellular senescence and promote collagen production. This local action aims to reverse or slow visible signs of skin aging, such as wrinkles and loss of volume, without the systemic side effects of oral rapamycin.

Promising for skin aging, but long-term effects and safety are unproven.
