Contact Dermatitis Treatment in
Marietta & East Cobb
Board-certified dermatology care for allergic and irritant contact dermatitis – accurate patch testing, targeted treatment, and long-term prevention strategies.
What Is Contact Dermatitis?
Contact dermatitis is an inflammatory skin reaction that occurs when the skin comes into direct contact with a substance that causes irritation or an allergic response. It's one of the most common dermatological conditions, affecting millions of Americans each year.
There are two primary types: irritant contact dermatitis (caused by direct chemical damage to the skin) and allergic contact dermatitis (caused by an immune system reaction to a specific allergen). Both produce similar symptoms – redness, itching, swelling, and sometimes blistering – but require different diagnostic and treatment approaches.
Without proper identification of the triggering substance, contact dermatitis can become chronic, leading to thickened skin, persistent discomfort, and significant impact on quality of life. A board-certified dermatologist can pinpoint the exact cause and develop a targeted avoidance and treatment plan.
ICIrritant Contact Dermatitis
The most common type, accounting for about 80% of cases. Caused by direct chemical or physical damage to the skin barrier. Common irritants include soaps, detergents, solvents, acids, and prolonged water exposure. Symptoms can appear within minutes to hours of contact.
ACAllergic Contact Dermatitis
An immune-mediated delayed hypersensitivity reaction. The body develops sensitivity to a specific substance after repeated exposure. Common allergens include nickel, fragrances, preservatives, latex, and poison ivy. Symptoms typically appear 24 – 72 hours after contact.
Patch testing is the gold standard for diagnosing allergic contact dermatitis – identifying the exact allergen so you can avoid it and prevent future flare-ups.
Why Contact Dermatitis Develops
Contact dermatitis occurs when the skin reacts to an external substance. Understanding the cause is essential for effective treatment and prevention.
Chemical Irritants
Soaps, detergents, cleaning products, solvents, and industrial chemicals can strip the skin's protective barrier. Prolonged or repeated exposure leads to irritant contact dermatitis, even without an allergic component.
Allergens & Sensitizers
Nickel (jewelry, belt buckles), fragrances, preservatives (formaldehyde releasers), latex, hair dyes, and plant oils (poison ivy, poison oak) are among the most common allergens that trigger immune-mediated reactions.
Occupational Exposure
Healthcare workers, hairdressers, mechanics, food handlers, and construction workers face higher risk due to frequent contact with irritants and allergens. Wet work and glove use can compound the problem.
Compromised Skin Barrier
Pre-existing conditions like eczema, dry skin, or previous skin damage make the barrier more vulnerable. A weakened barrier allows irritants and allergens to penetrate more easily, increasing sensitivity.
How We Treat Contact Dermatitis at DESSNA
We prioritize identifying the exact cause first, effective treatment second, and long-term prevention always – so your skin heals and stays clear.
Clinical Evaluation & History
Your dermatologist conducts a thorough examination of the affected areas and takes a detailed history – including occupation, hobbies, products used, and timeline of symptoms. This helps narrow down potential triggers before testing.
Patch Testing & Diagnosis
For suspected allergic contact dermatitis, we perform comprehensive patch testing. Small amounts of common allergens are applied to the skin under adhesive patches for 48 hours, then read at 48 and 96 hours to identify specific sensitivities.
Treatment & Avoidance Plan
Based on your results, we create a personalized treatment plan combining anti-inflammatory medications with a detailed allergen avoidance strategy. We provide product alternatives, workplace recommendations, and long-term skin barrier support.
Contact Dermatitis Treatment Options at Our Marietta Practice
Your treatment plan is tailored to the type and severity of your dermatitis, identified triggers, and affected areas. Here are the tools we use to heal and protect your skin.
Topical Corticosteroids
Prescription-strength anti-inflammatory creams and ointments reduce redness, swelling, and itching. Potency is matched to the severity and location of the rash – stronger for thick skin areas, milder for the face and folds.
Calcineurin Inhibitors
Non-steroidal anti-inflammatory creams (tacrolimus, pimecrolimus) are ideal for delicate areas like the face, eyelids, and skin folds where long-term steroid use is not recommended.
Barrier Repair & Emollients
Medical-grade moisturizers and barrier repair creams restore the skin's protective function. Regular use between flares strengthens the barrier and reduces susceptibility to future reactions.
Patch Testing
Comprehensive allergen panel testing identifies specific triggers. We test for 80+ common allergens including metals, fragrances, preservatives, rubber chemicals, and topical medications.
Phototherapy
Narrowband UVB light therapy can help manage chronic contact dermatitis that doesn't respond adequately to topical treatments. Controlled UV exposure modulates the immune response in the skin.
Allergen Avoidance Planning
Detailed guidance on avoiding identified triggers, including safe product alternatives, workplace modifications, and protective strategies. We provide written allergen lists and product recommendations.
Top Allergens Identified by Patch Testing
These are the most common allergens we identify in our Marietta practice through comprehensive patch testing:
Jewelry, belt buckles, eyeglass frames
Perfumes, lotions, soaps, detergents
Cosmetics, shampoos, wet wipes
Metal alloys, paints, cement
Antibiotic ointments, ear/eye drops
Gloves, elastic bands, shoes
Why Professional Diagnosis Is Essential
Contact Dermatitis vs. Eczema
Atopic dermatitis (eczema) and contact dermatitis can look identical. However, eczema is a chronic condition driven by genetic and immune factors, while contact dermatitis has a specific external trigger. Treatment differs significantly – and misdiagnosis leads to ongoing flare-ups.
Contact Dermatitis vs. Fungal Infections
Fungal infections (tinea, ringworm) can mimic contact dermatitis with red, scaly, itchy patches. Treating a fungal infection with steroids (a common contact dermatitis treatment) can actually worsen the condition. Accurate diagnosis prevents this cycle.
If you have a rash that keeps coming back, won't respond to treatment, or appears in a specific pattern, patch testing can identify the exact cause – and end the cycle.

Contact Dermatitis Treatment FAQs
Answers to the questions our Marietta and East Cobb patients ask most about contact dermatitis care.
Irritant contact dermatitis is caused by direct chemical damage to the skin (like harsh soaps or solvents) and can affect anyone with enough exposure. Allergic contact dermatitis is an immune system reaction to a specific substance – only people who have developed sensitivity to that allergen will react. Patch testing can distinguish between the two.
