Treatment of Contact Dermatitis on the Face
Diagnosis and Assessment
- The pattern and morphology of facial dermatitis are unreliable in distinguishing between irritant, allergic, or endogenous dermatitis, making proper assessment crucial 1
- A detailed history should include initial location of symptoms, spread pattern, and relationship to specific products or activities 1
- Patch testing is recommended for persistent cases to identify specific allergens 2, 1
First-Line Treatment
- Identify and completely avoid the triggering irritant or allergen 1
- Use gentle cleansers and soap substitutes instead of harsh soaps 1
- Apply moisturizers immediately after washing to repair the skin barrier 1
Special Considerations for Facial Contact Dermatitis
- The face is particularly sensitive to cosmetics, sunscreens, and fragrances which are common triggers 3
- Subjective irritancy often occurs on the face within minutes of contact with cosmetic or sunscreen constituents 3
- Use moisturizers packaged in tubes rather than jars to prevent contamination 1
Second-Line Treatments
- For severe or recalcitrant cases not responding to topical corticosteroids, consider topical tacrolimus as an alternative to steroids 4, 3
- Systemic therapies such as azathioprine or ciclosporin may be used for extensive or severe cases 3
- Phototherapy may be used for chronic cases, particularly for hand dermatitis 3
Preventive Measures
- Barrier creams alone have questionable value in protecting against irritants 4
- After-work creams have shown benefit in reducing irritant contact dermatitis 4
- Avoid products containing known irritants, topical antibiotics, and disinfectant wipes 1
Common Pitfalls to Avoid
- Overuse of topical corticosteroids on the face can lead to skin thinning, telangiectasia, and perioral dermatitis 1
- Failure to identify and avoid the causative agent will result in persistent dermatitis 2
- Using very hot water for washing can exacerbate irritant contact dermatitis 1
- Over-reliance on barrier creams may give a false sense of security 4
Prognosis
- If the patient can completely avoid the cause of contact dermatitis, the condition will clear 4
- Prognosis for occupational contact dermatitis is often poor, with only 25% of patients completely healing in some studies 4
- Allergic contact dermatitis carries a worse prognosis than irritant contact dermatitis unless the allergen is identified and avoided 3
