Contact dermatitis is an inflammatory skin reaction that occurs when your skin comes into direct contact with a substance that either irritates it or triggers an allergic response. The rash typically appears as red, itchy, swollen patches — sometimes with blisters or cracking — at the exact site of contact. Common culprits in India include nickel in jewellery, bindi adhesives, henna (paraphenylenediamine), rubber in footwear, textile dyes, cement, and household detergents. Unlike eczema, contact dermatitis has a clear external cause. Identifying and eliminating the trigger is the foundation of treatment. DermaVue dermatologists use standardised patch testing to pinpoint your specific allergen, then design a barrier repair and avoidance protocol tailored to your lifestyle.
Contact dermatitis is a type IV delayed hypersensitivity reaction (allergic) or a direct cytotoxic response (irritant) affecting the epidermis and superficial dermis. Allergic contact dermatitis (ACD) involves Langerhans cell antigen presentation, T-lymphocyte sensitisation, and subsequent cytokine-mediated inflammation upon re-exposure — typically peaking 48–72 hours after contact. Irritant contact dermatitis (ICD) results from direct keratinocyte damage by chemical or physical agents, disrupting the stratum corneum lipid barrier and activating innate immune mediators including IL-1α, TNF-α, and prostaglandins.[1] Indian studies report nickel sulphate, potassium dichromate, fragrance mix, and paraphenylenediamine as the most prevalent patch-test–positive allergens in the subcontinent, with occupational exposure patterns differing significantly from Western cohorts.

No, contact dermatitis is absolutely not contagious. It cannot spread from person to person through touching or sharing items. It is an individual immune reaction (allergic type) or a localised irritant response specific to your own skin's sensitivity to a particular substance. The rash only appears on skin that directly contacted the allergen or irritant.
The top allergens identified through patch testing in Indian studies are nickel sulphate (costume jewellery, watch straps), potassium dichromate (cement, leather), paraphenylenediamine (henna, hair dyes), fragrance mix (perfumes, cosmetics), and colophony (bindi adhesives, plasters). India-specific triggers also include kumkum, sindoor, rubber chemicals in chappals, and textile dyes. Occupational irritants such as detergents, cement, and pesticides are equally common.
Contact dermatitis is triggered by an identifiable external substance touching the skin — remove the trigger and the rash resolves. Atopic eczema (atopic dermatitis) is a genetic, chronic condition driven by an inherent skin barrier defect and immune dysregulation, often starting in childhood with no single external cause. However, people with atopic eczema are more susceptible to developing contact dermatitis because their compromised skin barrier allows easier allergen penetration.
Patch testing is painless. Small chambers containing standardised allergens are taped to your upper back and left in place for 48 hours. The dermatologist reads the results at 48 hours and again at 72–96 hours, grading any positive reactions. You should avoid wetting the test area and heavy exercise during the testing period. The procedure is safe with no needles and no blood draws — it simply recreates controlled micro-exposures to identify your specific allergen.
DermaVue consultation fee is ₹300 at most branches. Patch testing with the Indian baseline allergen series is a separate diagnostic fee discussed during consultation. Topical medications and barrier repair prescriptions vary based on severity. Chemical peels for post-inflammatory pigmentation range ₹1,500–3,500 per session. All costs are discussed transparently at your first visit — no hidden charges.
Yes, contact dermatitis will recur if you are re-exposed to the allergen or irritant. Unlike infections that can be "cured," allergic contact dermatitis represents a permanent immunological sensitisation. Once your immune system recognises an allergen, it will always react to it. That is why identification through patch testing and lifelong avoidance of the specific allergen is the most important part of management. With proper avoidance, recurrence is preventable.
