From the Guidelines
Skin hypersensitivity is most commonly caused by allergic contact dermatitis, irritant contact dermatitis, and other inflammatory dermatoses such as eczema and seborrheic dermatitis. These conditions can be triggered by various factors, including:
- Harsh skincare products containing fragrances and alcohol
- Environmental factors like extreme temperatures and pollution
- Allergic reactions to certain ingredients, such as nickel, neomycin, and fragrances
- Medical conditions like eczema, seborrheic dermatitis, and psoriasis
- Certain medications, such as antibiotics and antifungal agents, which can cause contact dermatitis or photosensitivity reactions 1.
The management of skin hypersensitivity involves removing the sensitizing agent, applying topical corticosteroids or other anti-inflammatory agents, and using gentle skincare products that are fragrance-free and hypoallergenic 1. Patch testing can be used to diagnose allergic contact dermatitis and identify the specific allergen responsible for the reaction 1. It is also important to note that some medications, such as amiodarone and thiazide diuretics, can cause photosensitivity reactions, and patients should be advised to take precautions to avoid excessive sun exposure 1.
In terms of prevention, using gentle skincare products, avoiding harsh chemicals and fragrances, and protecting the skin from excessive sun exposure can help to reduce the risk of skin hypersensitivity 1. Additionally, patch testing new products and consulting a dermatologist for persistent sensitivity can help to identify and manage skin hypersensitivity reactions 1. Overall, a comprehensive approach that takes into account the various causes and triggers of skin hypersensitivity is necessary to effectively manage and prevent this condition.

Common Causes of Skin Hypersensitivity
The common causes of skin hypersensitivity can be attributed to various factors, including:

- Allergic settings and intolerance to certain substances 3, 4
- Cosmetics and skin care products, particularly those containing potentially irritant substances 3, 5
- Occupational skin diseases or chronic exposure to irritants 5
- Constitutional anomalies, such as a thinner stratum corneum with a reduced corneocyte area, alterations in vanilloid receptors, and changes in neuronal transmission 5, 6
- Diminished barrier function, heightened neurosensory input, and enhanced immune responsiveness 6
