Thyroid
Thyroid hormones help set the pace of skin cell turnover and the hair growth cycle. Changes in thyroid function can show up as dryness, dullness, or shedding.

Aesthetic Metabolism™ (noun)
The way hormones, thyroid function, and metabolic health express themselves in the skin, hair, and the body's response to cosmetic treatment.
Term coined by Dr. Anna Frisch, MD, PhD, Board Certified in Endocrinology. First published October 2026.
Your skin has a metabolism
Skin is one of the most hormonally active organs in the body. It renews itself, builds collagen, produces oil, grows hair, and heals on signals sent by your endocrine system. When those signals shift, your appearance shifts with them.
Aesthetic Metabolism™ is the name Dr. Anna Frisch gives to that connection. It is one of the lenses she uses to plan cosmetic medicine at Palm Beach Cosmetic Medicine.
The four signals behind how you look
Estrogen and androgens
Estrogen supports collagen, hydration, and skin thickness, which is why skin often changes through perimenopause and menopause. Androgens influence oil production, breakouts, and hair patterns.
Insulin and blood sugar
Elevated blood sugar over time contributes to glycation, a process that stiffens collagen and elastin. Insulin signaling also influences oil production and pigmentation.
Cortisol
Sustained stress hormones can slow healing, thin the skin, and weaken its protective barrier.
Why Aesthetic Metabolism™ matters for your results
Two people can receive the same treatment and see different results. Aesthetic Metabolism™ helps explain why. How your skin builds collagen after laser or microneedling, how your scalp responds to PRP, and how well your skin holds hydration are all shaped by what is happening inside your body.
That understanding informs how Dr. Frisch plans care at Palm Beach Cosmetic Medicine.
