Acne can feel mysterious until you zoom out and see the pattern: your skin is responding to signals from blood sugar, hormones, inflammation, stress, and even your environment. Dr. Shannon C. Trotter sits down with board-certified dermatologist Dr. Katie Varman of Shine Functional Dermatology to unpack what’s happening under the surface, and why treating acne is often about finding your biggest driver rather than hunting for a single “bad” ingredient.

We dig into the science linking insulin to acne, including how frequent high-glycemic foods can activate growth pathways (including mTOR and insulin-like growth factor signaling) that increase oil production and pore-clogging skin buildup. We also talk dairy and why it can be a powerful trigger for some people, plus how a continuous glucose monitor (CGM) can help you personalize what actually spikes your blood sugar. If you’ve ever wondered why one person can eat pizza and be fine while another breaks out overnight, we explain the “threshold” concept and how to test changes without living on a permanent restriction plan.

From there, we connect the dots on gut health and the gut microbiome, probiotics and postbiotics, and why processed foods can quietly undermine skin health. We also get real about stress and acne, breaking down the HPA axis, cortisol, and how your skin can behave like an endocrine organ. Finally, we cover endocrine disrupting chemicals like phthalates and BPA, why synthetic fragrance is a common exposure, and simple swaps that can reduce your load without panic.

Skincare on social media can feel like a nonstop emergency: one day red light masks are “the secret,” the next day exosomes are “the future,” and somewhere in the middle you’re told sunscreen is poison. We wanted to slow that down. We’re joined by board-certified dermatologist Dr Dustin Portella to talk through why people are increasingly turning to TikTok, Instagram, and quick searches for skincare answers and what that shift looks like inside real clinic visits.

We dig into red light therapy with a clear lens: where it may help, what at-home devices can realistically do, and why it should never crowd out the basics that actually protect skin over time like daily SPF, antioxidants, and topical retinoids. Then we tackle exosomes skincare, including the big questions patients are already asking about sourcing, regulation, safety, and whether the evidence has caught up with the marketing.

From there we get into K-beauty skincare routines, not just the ingredients and hydration benefits, but the ritual and psychology of self-care and why “more steps” is not always better. We also address sunscreen myths and the way sound bites distort research, plus the supplement boom and why there’s rarely a true shortcut for skin health.

If you’ve ever felt pulled between curiosity and skepticism, this conversation gives you a calm framework for evaluating viral skincare trends without losing your mind or your money. Subscribe, share with a friend who lives on skincare reels, and leave a review telling us which trend you want us to myth-bust next.

That Oscars moment put the word “alopecia” on everyone’s lips, but the real story is what happens when hair loss is autoimmune and how quickly it can change someone’s life. I sit down with board-certified dermatologist Dr. Eric Dominguez to explain alopecia areata in plain language, from the classic coin-shaped patches to the tougher presentations like diffuse thinning, ophiasis patterns, and isolated eyebrow or eyelash loss that can be even harder to hide.

We get practical about diagnosis and next steps: what we look for on exam, when a scalp biopsy helps confirm the cause, and why the scalp can feel like a uniquely stressful place to do a procedure. We also dig into the questions patients ask every day in clinic: Did stress trigger this? Is it genetic? What’s the risk of losing more hair or progressing to alopecia totalis or alopecia universalis? And if you have alopecia areata, what other autoimmune conditions like thyroid disease, vitiligo, eczema, or psoriasis should be on your radar?

Then we move to treatment, including why alopecia areata is not a cosmetic problem and why getting help early matters. We cover the full range, from topical and intralesional corticosteroids for localized disease to the newer FDA-approved oral JAK inhibitors that are changing what hair regrowth can look like for severe cases. We also set realistic expectations: this can be a chronic, relapsing condition, and stopping an effective medication may mean losing progress.
