Eczema, Psoriasis, or Rosacea? How to Identify and Treat Skin Conditions

Skin conditions like eczema, psoriasis, and rosacea are among the most common dermatological issues affecting millions of people worldwide. While they may share some similarities, each condition has distinct symptoms, causes, and treatment options. Understanding the differences between these conditions is crucial for effective management and relief.

Dr Shaun Segal, a leading expert in dermatology, provides the latest insights and treatment advancements for 2025, helping patients navigate these skin concerns with confidence. In this comprehensive guide, we’ll break down the characteristics of each condition, discuss their causes, and explore the most effective treatment options.

Understanding Eczema (Atopic Dermatitis)

What Is Eczema?

Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition that causes intense itching, redness, and dryness. It is most commonly seen in infants and children, but adults can also develop or continue to experience symptoms throughout life.

Eczema is not contagious, but it can significantly impact an individual’s quality of life due to persistent discomfort and frequent flare-ups. The condition tends to run in families, indicating a strong genetic component.

What Causes Eczema?

Eczema is caused by a combination of genetic and environmental factors. Individuals with eczema often have an overactive immune system that reacts strongly to irritants or allergens. Some of the most common triggers include:

• Allergens (pollen, pet dander, dust mites)
• Irritants (harsh soaps, detergents, fragrances)
• Weather changes (cold and dry air or excessive humidity)
• Stress and anxiety
• Food allergies (dairy, nuts, eggs, soy)

Symptoms of Eczema

The symptoms of eczema can vary in severity but typically include:

✅ Dry, cracked, and scaly skin
✅ Redness and inflammation
✅ Intense itching (which can worsen at night)
✅ Oozing or crusting lesions in severe cases
✅ Thickened, leathery patches due to chronic scratching

Updated Treatments for Eczema (2025)

Dr Shaun Segal recommends the latest treatment options for managing eczema effectively:

1. Moisturization: Regular application of fragrance-free, hypoallergenic moisturizers helps maintain skin hydration and reduce flare-ups.
2. Topical Corticosteroids: Low to moderate-strength steroids help reduce inflammation and control itching.
3. Antihistamines: Oral antihistamines, such as cetirizine, can help control nighttime itching and improve sleep.
4. Biologic Therapies: Newer biologic drugs like dupilumab and tralokinumab target specific immune pathways and offer relief for severe eczema.
5. Lifestyle Modifications: Avoiding harsh soaps, taking lukewarm showers, and wearing soft cotton clothing can prevent irritation.

Understanding Psoriasis

What Is Psoriasis?

Psoriasis is a chronic autoimmune skin disorder that speeds up the life cycle of skin cells, causing thick, scaly plaques to form on the skin’s surface. Unlike eczema, psoriasis is an autoimmune disease, meaning the immune system mistakenly attacks healthy skin cells.

Psoriasis is not contagious, but it can be genetically inherited, with many individuals having a family history of the condition.

What Causes Psoriasis?

The exact cause of psoriasis is not fully understood, but it is linked to an overactive immune system that causes rapid skin cell production. Common triggers include:

• Infections (strep throat, skin infections)
• Stress and emotional trauma
• Cold weather and dry climates
• Smoking and excessive alcohol consumption
• Certain medications (beta-blockers, lithium)

Symptoms of Psoriasis

Psoriasis symptoms vary based on the type of psoriasis, but the most common form, plaque psoriasis, includes:

✅ Thick, raised patches of red skin covered with silvery-white scales
✅ Itching, burning, or soreness
✅ Cracked skin that may bleed
✅ Discoloration or pitting of the nails
✅ Joint pain in psoriatic arthritis

Updated Treatments for Psoriasis (2025)

Dr Shaun Segal emphasizes the importance of a multifaceted approach to treating psoriasis:

1. Topical Treatments: Corticosteroids, vitamin D analogs (calcipotriol), and salicylic acid-based creams can reduce scaling and inflammation.
2. Phototherapy (Light Therapy): UVB light therapy helps slow down skin cell turnover and ease symptoms.
3. Systemic Medications: Severe psoriasis can be treated with methotrexate, cyclosporine, or biologics such as secukinumab or risankizumab.
4. Lifestyle Changes: Maintaining a healthy weight, reducing alcohol intake, and managing stress can help reduce flare-ups.

Understanding Rosacea

What Is Rosacea?

Rosacea is a chronic inflammatory skin condition that primarily affects the face, causing persistent redness, visible blood vessels, and acne-like breakouts. It can worsen over time if left untreated.

Unlike eczema and psoriasis, rosacea typically develops in adults, especially those with fair skin and a history of sensitivity to sun exposure.

What Causes Rosacea?

The exact cause of rosacea is unclear, but researchers believe it is linked to:

• Genetics (family history of rosacea)
• Abnormal immune responses
• Demodex mites (skin parasites)
• Environmental triggers (hot drinks, spicy food, alcohol, sun exposure)

Symptoms of Rosacea

Rosacea symptoms can be mistaken for acne or sunburn but include:

✅ Persistent redness, especially on the cheeks and nose
✅ Visible blood vessels (telangiectasia)
✅ Small, pus-filled bumps (similar to acne)
✅ Burning or stinging sensations
✅ Eye irritation (ocular rosacea)

Updated Treatments for Rosacea (2025)

Dr Shaun Segal suggests the latest treatment options for rosacea:

1. Topical Medications: Metronidazole, azelaic acid, and ivermectin can reduce inflammation and redness.
2. Oral Antibiotics: Low-dose doxycycline can control flare-ups.
3. Laser Therapy: Vascular laser treatments help reduce visible blood vessels.
4. Lifestyle Changes: Avoiding sun exposure, spicy foods, and hot drinks can minimize rosacea triggers.
