Aesthetic & Regenerative Endocrinology

A concise, clinician-focused pocket reference on aesthetic and regenerative endocrinology — optimizing the skin–endocrine system for healthspan. It covers the physiology of endocrine aging, the decline of hormones and peptides across the lifespan, the organs of aging (skin, adipose tissue, and the gut), and evidence-graded interventions: peptides and bioregulators, hormone optimization, supplements and senotherapeutics, and lifestyle and circadian medicine — through to the regenerative frontier of endocrine tissue replacement. Strength-of-evidence ratings, clinical pearls, testing and monitoring references, and citations appear throughout.
