In Part 1 of this listener request episode, we discuss the molecular biology of skin hydration and what is required for skin homeostasis. We dive into the details of what our skin makes in order to keep hydrated, called natural moisturizing factors, what happens when we apply these compounds to our skin, and what we can apply to our skin to help seal in the hydration. We also discuss the new area of synthetic peptides that scientists are creating in order to mimic a botox-like effect in the skin.
