Summer Skin Symptoms: Causes and Treatments - Dermatology

More Info

---

Summer skin symptoms can often be attributed to a variety of factors, including sun exposure, heat, humidity, and even allergic reactions. Based on your description of having small, round or oval-shaped red bumps on your hands that become itchy and swollen when exposed to sunlight, it sounds like you may be experiencing a condition known as polymorphous light eruption (PMLE) or possibly a form of heat rash or sun allergy.

Understanding Your Symptoms:
1. Polymorphous Light Eruption (PMLE): This is a common skin condition that occurs in response to sunlight exposure. It typically manifests as itchy red bumps or patches on areas of the skin that have been exposed to the sun. The bumps can appear within hours or days after sun exposure and may be accompanied by a burning or stinging sensation. PMLE is more common in individuals with fair skin and can be exacerbated by heat and humidity.

2. Heat Rash (Miliaria): This occurs when sweat ducts become blocked, trapping sweat beneath the skin. It often presents as small, red, itchy bumps and can occur in hot and humid conditions. Heat rash is usually self-limiting and resolves once the skin cools down.

3. Sun Allergy: Some individuals may develop an allergic reaction to sunlight, leading to symptoms similar to PMLE. This can include redness, itching, and the formation of small blisters or bumps.

4. Dry Skin and Sun Exposure: The combination of sun exposure and dry skin can lead to irritation and peeling. If your skin is already dry, exposure to the sun can exacerbate this condition, leading to the symptoms you described.

Treatment Options:
1. Avoid Sun Exposure: The most effective way to prevent these symptoms is to limit sun exposure, especially during peak hours (10 AM to 4 PM). Wearing protective clothing, such as long sleeves and wide-brimmed hats, can help shield your skin from UV rays.

2. Sunscreen: Use a broad-spectrum sunscreen with an SPF of 30 or higher. Apply it generously to all exposed skin at least 15 minutes before going outside and reapply every two hours, or more frequently if swimming or sweating.

3. Moisturizers: Keeping your skin well-hydrated can help prevent dryness and irritation. Look for moisturizers that contain ingredients like ceramides, hyaluronic acid, or glycerin. Apply moisturizer immediately after bathing and throughout the day as needed.

4. Topical Treatments: Over-the-counter hydrocortisone cream can help reduce inflammation and itching. If your symptoms are severe or persistent, a dermatologist may prescribe stronger topical steroids or other medications.

5. Antihistamines: If itching is bothersome, oral antihistamines may provide relief. These can help reduce the itchiness associated with allergic reactions or skin irritations.

6. Cool Compresses: Applying a cool, damp cloth to the affected areas can help soothe itching and reduce inflammation.

7. Consult a Dermatologist: If your symptoms persist or worsen, it is essential to consult a dermatologist. They can provide a proper diagnosis and recommend specific treatments tailored to your condition.

In summary, your symptoms likely stem from a reaction to sun exposure, possibly PMLE or heat rash. Taking preventive measures, such as avoiding sun exposure and using appropriate skincare products, can significantly alleviate your symptoms. If necessary, seek professional medical advice for a tailored treatment plan.
