Can an Underactive Thyroid Cause Skin Rashes? What to Know
Dry, itchy, or discolored patches on your skin can sometimes be more than just a topical issue. If you're living with hypothyroidism, your thyroid could be affecting your skin in surprising ways—including causing rashes.
What hypothyroid-related rashes look like
Rashes linked to an underactive thyroid tend to be subtle but persistent. Common symptoms include dry, scaly patches, red or pale discoloration, and areas of thickened skin. Some people may notice a dull rash that doesn’t respond to over-the-counter creams. While not always itchy, these rashes can be uncomfortable and may appear alongside other signs of hypothyroidism like fatigue, weight gain, and sensitivity to cold.
Where skin symptoms most commonly appear
Skin issues tied to hypothyroidism most often develop in areas with thinner skin or poor circulation. This includes the elbows, knees, shins, scalp, and the face—particularly around the eyes and mouth. In some cases, rashes appear in body folds or on the neck, a region commonly affected by thyroid hormone imbalances. People with autoimmune hypothyroidism (like Hashimoto’s thyroiditis) may also experience hives or eczema-like patches in various parts of the body.
Texture and color changes to note
The skin of someone with hypothyroidism may feel rough or rubbery to the touch. It can appear paler than usual or have a yellowish hue due to changes in carotene metabolism. Some individuals experience puffy or swollen skin, especially on the face and hands. In chronic cases, the skin may crack, flake, or develop fissures. Noting the combination of dryness, roughness, and persistent dullness is key in identifying thyroid-related skin changes.
Mild vs. severe rash types
Mild rashes from hypothyroidism might be dismissed as simple dryness. These usually clear with moisturizers, but return quickly. More severe rashes—especially those associated with autoimmune thyroid disorders—can resemble dermatitis or even urticaria (hives). These may cause swelling, redness, and itchiness. In rare cases, people with severe untreated hypothyroidism may develop myxedema, where the skin thickens significantly and takes on a waxy texture.
When to consult a specialist
You should consider seeing a healthcare provider if your rash persists despite basic skincare, is accompanied by other hypothyroid symptoms, or worsens over time. A dermatologist can help rule out other skin conditions, while an endocrinologist can test your thyroid hormone levels. If you’ve already been diagnosed with hypothyroidism and your skin issues are new or intensifying, your medication dosage may need adjustment.

Additional insights into thyroid-related skin issues
- Hypothyroidism slows cell turnover, which can lead to a buildup of dead skin and dryness.
- Autoimmune reactions like Hashimoto’s may involve inflammation that affects the skin and hair.
- Medications such as levothyroxine can help regulate hormone levels and improve skin over time.
- Nutrient deficiencies common in thyroid disorders (like B12 or zinc) may worsen skin symptoms.
- Moisturizing regularly and using gentle skincare products can help manage symptoms externally.
Managing skin issues related to hypothyroidism starts with treating the underlying hormonal imbalance. While not every rash signals a thyroid issue, persistent skin changes should be evaluated in the context of overall health.
