Biology with Equilux™

Personalized Hormonal Wellness for Women and Men—Anywhere, Anytime

Equilux™ by NDA Aesthetics is more than a product—it’s the culmination of over 20 years of clinical expertise in aesthetics, functional medicine, and hormone optimization.

Created by husband-and-wife team Noelle Brown Diamond, RD, and Dr. Stuart Diamond, Equilux™ was born from their shared mission: to provide a real, science-backed approach to hormonal health that’s both accessible and elevated.
