Skin

Skin longevity is a clinical discipline when it rests on human evidence. A five-pathway framework for sorting what works, what's unproven, and what's hype.

A patient books for acne at forty-three. Another mentions, almost in passing, that her hair has been thinning for a year. A third has velvety darkening in the axillae that she assumes is a hygiene problem and has not mentioned to anyone.

Patients arrive asking about filler. The more useful question is what the face is reporting about the rest of the body.
