Can you smell with your skin?
“In our study, published in the Journal of Investigative Dermatology, we discovered that olfactory receptors can also be found in keratinocytes – the cells that form the outermost layer of the skin – and that activating these receptors increases the rate of proliferation and migration of these skin cells.”
Of course, my twisted brain is thinking about this. Maybe those wonderful-smelling products, e.g., tea-tree oil, might engender “healing” because of the way they “smell?”
