What Your Skin Is Trying To Tell You

Welcome to another edition of the Doctor's Note where we talk about what’s on our minds when it comes to your health.

This week I had the privilege of sitting down with my longtime colleague, friend, and trusted dermatologist, Dr. Joni Sago, to dig into what your skin might be telling you about your overall health. Dr. Sago reminds us how the skin, far from being just a surface organ, often acts as a mirror for what’s happening on the inside. Inflammatory skin conditions like eczema and psoriasis can actually signal broader systemic problems—sometimes even pointing the way toward underlying issues like metabolic syndrome, cardiovascular disease, or autoimmune disorders. We talked about the importance of treating these conditions holistically and not just putting a “band-aid” on them, because simply controlling a rash doesn’t address the root of the problem and can leave bigger issues unaddressed.

Our conversation also covered the shifting landscape of dermatologic treatments, especially the game-changing potential of biologics—targeted medications that are having incredible results not just in clearing up skin but also by potentially lowering lifelong risks for other diseases. Dr. Sago impressed on me just how much an integrative approach matters: assessing gut health, stress, hormonal changes, and genetics are all parts of unraveling what’s happening with the skin. We touched on the frustrations of a healthcare system that doesn’t always support this approach, as well as the liberating experience of stepping out of insurance-driven practice, giving doctors more time and energy to do what’s best for their patients.

PODCAST NOTES 

• The skin frequently serves as an early warning system for internal diseases, functioning as a “mirror” that reflects deeper health issues—so recurrent or chronic skin problems may signal the need to look for underlying systemic inflammation or imbalances, not just to focus on cosmetic improvement.

• Chronic inflammatory conditions such as eczema and psoriasis are more than just skin deep; they are closely interconnected with higher risks of diseases like arthritis, cardiovascular disease, and metabolic syndrome. Addressing only the rash without exploring these broader implications puts patients at risk of missing and untreated health problems that can become serious over time.

• The structure of our healthcare system—with its emphasis on expediency, electronic coding, and insurance mandates—often works against comprehensive, root-cause medical evaluation, contributing to physician burnout and patient dissatisfaction, as crucial aspects of care get sacrificed for administrative ease.

• Holistic dermatology requires time for detailed patient education and a willingness to explore lifestyle contributors such as diet, sleep, stress history, and even childhood trauma. This deeper approach allows for better disease management and helps set realistic expectations about treatment responses, timelines, and side effects.

• Biologics represent a major advancement in the treatment of skin diseases like eczema and psoriasis because they target specific inflammatory pathways (such as interleukins or TNF) with minimal side effects, drastically improving quality of life compared to the old broad-spectrum immunosuppressants. Some biologics, such as dupilumab, are even safe for young children and don’t require ongoing blood testing.

• Research is showing that early, targeted use of biologics can help alter the long-term course of diseases, such as lowering the risk or even preventing the development of related conditions like psoriatic arthritis and reducing cardiometabolic risk, thanks to the potent lowering of inflammation markers like CRP.

• Overweight, insulin resistance, and diabetes profoundly raise the risk for inflammatory skin diseases—particularly psoriasis and hidradenitis suppurativa. Effective dermatologic treatment therefore often requires concurrent management of metabolic health, sometimes utilizing medications like metformin or GLP-1s alongside traditional topical and biologic interventions.

• Proper sun protection makes a significant difference in skin cancer prevention, but it isn’t about blanketing your whole body with sunscreen every day. Instead, protecting the head and neck with mineral-based, non-toxic formulations (such as a tinted mineral sunscreen) offers high protection where it’s most needed. Avoiding spray sunscreens, especially on children, is crucial due to their chemical risks, and supplementing with niacinamide can further lower the risk of new skin cancers in high-risk individuals.

Pay attention to your skin—it’s not just about looks, but about what may be brewing underneath. If you’re dealing with persistent rashes, scales, or boils, consider seeking an integrative evaluation that looks beyond the surface. Ask your provider about targeted therapies like biologics if standard treatments aren’t working, and don’t ignore the role of gut health, stress, hormones, and nutrition. 

Finally, be mindful of your sun protection—prioritize the face and neck, choose safe products, and consider supplements like niacinamide if you’re at risk. Your skin may just be giving your body’s first warning sign—listen to it and let’s keep you healthy from the inside out!

Stay educated. Stay healthy.

Till next week.
