To The Root
Internal Causes of Melasma

In this episode of To The Root, Robyn Spangler offers an in-depth exploration of melasma as a complex, internally driven skin condition—not simply a cosmetic concern or a consequence of sun exposure.
Robyn breaks down the interconnected roles of estrogen signaling, iron metabolism, antioxidant status, and light exposure in driving melanin overproduction. She explains how hormonal shifts, impaired iron recycling, nutrient imbalances, and a disrupted circadian environment can create a biological environment that fuels hyperpigmentation, and why addressing melasma requires more than topical management.
You will gain insight into the importance of comprehensive assessment, realistic timelines for improvement, and targeted interventions that address root causes rather than short-term symptoms. Robyn emphasizes that sustainable change is achieved by supporting physiological pathways—not by restrictive diets or aggressive skin treatments.
This episode provides a clear, evidence-informed framework for understanding melasma from a functional and integrative perspective, and highlights why internal investigation is essential to long-term results.

Highlights:
- How estrogen receptors on melanocytes influence pigment production, especially during pregnancy, perimenopause, or hormonal therapy
- Why “anemia” may mask impaired iron recycling and how excess unbound iron contributes to oxidative stress and pigmentation
- The role of vitamin E and antioxidant status in supporting cell membrane stability, skin resilience, and hormone metabolism
- Expected timelines for meaningful change in melasma and why long-term strategy is essential for success
The impact of artificial blue light, disrupted circadian rhythms, and strategic natural light exposure on pigment regulation - Why melasma is rarely diet-driven and does not typically require restrictive nutrition protocols
- The value of comprehensive testing to evaluate hormone metabolism, iron status, nutrient sufficiency, and detoxification capacity
