Your Skin Could be Telling You More than you Think!

What Is Acanthosis Nigricans?

Understanding What Your Skin Is Trying to Tell You

Have you ever noticed dark, velvety patches of skin appearing on your neck, underarms, or inner thighs? You’re not alone. This common condition is called Acanthosis Nigricans (AN)—and it’s more than just a cosmetic concern. It can be a signal from your body that something deeper needs attention.

What Does Acanthosis Nigricans Look Like?

Acanthosis Nigricans presents as:

• Darkened, thickened, velvety skin
• Most commonly found on the back of the neck, underarms, groin, elbows, or knees
• May be slightly itchy or have a subtle odor

It’s not a rash or an infection, and it isn’t contagious. But it is a sign that your body may be experiencing hormonal or metabolic changes.

What Causes It?

The most common root cause of acanthosis nigricans is insulin resistance, a condition where your cells stop responding effectively to insulin. As insulin builds up in the bloodstream, it can stimulate the growth of skin cells and increase pigmentation—leading to the thickened, dark patches characteristic of AN.

Other contributing factors include:

• Type 2 diabetes or prediabetes
• Polycystic Ovary Syndrome (PCOS)
• Obesity
• Hormonal imbalances (like hypothyroidism or Cushing’s syndrome)
• Certain medications (such as steroids or hormonal treatments)
• Rare genetic syndromes or malignancies (in uncommon cases)

Why It Matters

Acanthosis nigricans often appears before blood sugar or hormone issues are diagnosed. It can serve as an early red flag for:

• Prediabetes or Type 2 Diabetes
• Metabolic Syndrome
• PCOS in teens or women of childbearing age
• Underlying endocrine disorders

That’s why ignoring it—or simply trying to treat it topically—won’t address the real issue. Functional and integrative care looks at what’s driving it from the inside out.

What Can You Do About It?

The good news? Acanthosis nigricans is often reversible when the underlying cause is treated. Here’s where we start:

1. Address Insulin Resistance

• Adopt a low-glycemic, anti-inflammatory diet high in protein, fiber, and healthy fats
• Focus on blood sugar stability with smaller, balanced meals
• Consider supplements like berberine, inositol, or magnesium (based on your provider’s recommendations)

2. Optimize Hormone Balance

• If PCOS, thyroid dysfunction, or cortisol issues are contributing, lab testing and targeted care can make a big difference

3. Support Weight Loss (if appropriate)

• Even a modest reduction in weight can improve insulin sensitivity and reduce skin changes

4. Use Topical Treatments (as a support—not a cure)

• Exfoliating agents like glycolic acid, retinoids, or gentle peels can help improve the appearance of affected skin
• But they won’t fix the root cause on their own

When to See a Provider
