7 Skin Signs of Insulin Resistance: Unveiling the Root Causes

Hello, everyone! Dr. Berry here, and today we’re diving deep into a topic that’s often overlooked but incredibly important: skin signs of insulin resistance. Understanding these signs is crucial for both your skin health and overall well-being.

Why Skin Signs Matter

First and foremost, let’s talk about why these skin signs matter. Insulin resistance isn’t just a precursor to diabetes; it’s a condition that affects your entire body, including your skin. Recognizing these signs early can make a significant difference in managing and treating related skin conditions.

Acanthosis Nigricans: More Than Just a Dark Patch

One of the most telling signs is Acanthosis nigricans. This condition is characterized by darkened skin on the neck, underarms, or groin. It’s almost always a sign of insulin resistance and metabolic syndrome, regardless of your skin pigment. If you notice these dark patches, it’s time to consult a healthcare provider for insulin resistance testing.

The Acne Connection

Did you know that hyperinsulinemia or insulin resistance can be present in teenagers with moderate to severe acne? That’s right, folks! Acne isn’t just a teenage problem; it’s a sign that something deeper is going on. Early testing and intervention are crucial.

Rosacea and Metabolic Health

Another skin condition that can be improved by addressing insulin resistance is rosacea. Many people suffer from this condition without realizing that their metabolic health could be the root cause. By managing insulin levels, you can improve and even eliminate rosacea symptoms.

Dietary Impact

Now, let’s talk about diet. Eating a high carbohydrate diet can either cause or worsen insulin resistance, hyperinsulinemia, and various skin conditions. Switching to a ketogenic or ketovore diet can help reduce chronically elevated levels of insulin and improve insulin sensitivity.


Understanding the skin signs of insulin resistance is not just about vanity; it’s about holistic health. By recognizing these signs early and taking appropriate action, you can prevent more severe health issues down the line.
