Feeding the Fire: Fat, Inflammation, & Psoriasis

What if the most inflammatory driver of psoriasis isn’t on the skin at all, but deep in visceral fat? We sit down with Dr. James Song to unpack how adipose tissue acts like a hormone-secreting organ, releasing cytokines that can fuel psoriasis and psoriatic arthritis. From the brain’s weight “set point” to genetics linking obesity and psoriasis risk, we reframe weight as biology—not a moral failing—and explain why that matters for treatment. We break down fat types, the cytokine cascade conne...

The Diversity Gap in Psoriasis Care

Psoriasis doesn’t look the same on every skin tone.

Beyond the Diagnosis: A Melanoma Warrior's Voice

A routine Saturday turned life-changing when Leah’s dad had a seizure behind the wheel—ER scans revealed brain lesions, and a full-body scan showed his lungs “lit up like a Christmas tree.” A biopsy confirmed stage four metastatic melanoma, forcing Leah and her mom into an accelerated crash course on brain radiation, immunotherapy, and caregiving.

No White Lies: The Truth About Vitiligo

A white patch on the skin shouldn’t erase someone’s story—or their options.

Unmasking the Mystery of Contact Dermatitis

Contact dermatitis affects up to 20% of people and can appear as either irritant (like a chemical burn) or allergic (an immune response after years of safe use).

Dr. Dathan Heyman shares cases—from plants to kitty litter—that highlight how hidden allergens trigger rashes, and how identifying them can bring l...
