The research was published Wednesday in the Journal of Investigative Dermatology.

Humans have about 350 olfactory receptors in the nose, but previous studies have shown they also exist in sperm, in the prostate, in kidneys and in our intestine. This is the first time that olfactory receptors have been found in keratinocytes—cells that form the outermost layer of the skin. And Hatt’s team discovered that when those receptors in the skin—called OR2AT4—were in proximity to synthetic sandalwood, they became activated, prompting cell proliferation and cell…
