Contact Dermatitis

What is contact dermatitis?
Contact dermatitis is an itchy, red rash that is observed in response to direct contact with irritants. It can take on multiple forms such as a red rash, scaly and dry skin, oozing blisters, or red bumps. The following are examples of substances that can trigger contact dermatitis: clothing, jewelry, soaps, lotions, cosmetics, fragrances, ointments, etc.

What is allergic contact dermatitis?
Allergic contact dermatitis is triggered by your immune system’s low tolerance to substances inducing irritation of the skin. It only affects the area of skin exposed directly to the allergen. Any amount of exposure to the allergen once an allergy is developed may lead to a reaction.

What is irritant contact dermatitis?
Irritant contact dermatitis is the most common type of contact dermatitis. It is a nonallergic reaction that only occurs when an irritating substance harms the outermost protective barrier of the skin. One can gradually develop a tolerance toward the irritant.

What does treatment look like?

• Topical Steroids: Topical steroids can be prescribed by a dermatologist to subdue itching and irritation of rash caused by contact dermatitis. Most creams and ointments are applied once or twice a day for two to four weeks, or as recommended by the dermatologist.
• Oral Medications: In severe cases, your dermatologist might prescribe oral steroids cases to overcome inflammation, antibiotics to battle infection caused by bacteria, and antihistamines to relieve itchiness.

How can I prevent it?

• Avoid irritants/allergens: Be aware of the cause of your irritation and avoid these substances. Ask your dermatologist to provide you with a list of gentle products that may suit your conditions.
• Avoid scratching: Continuous scratching on the affected area can cause more itching, irritation, discoloration, and possible scarring.
• Use a thick moisturizer
• Cover up with clothing/gloves: This decreases the urge to scratch and protects the skin from exposure to further irritation and allergens.
