L23.2

Clinical Causes: Presence of allergens in cosmetic products such as fragrances, preservatives, dyes, and certain botanical extracts. Repeated or prolonged skin contact with products like makeup, skincare creams, hair dyes, or perfumes. Sensitivity developed over time due to cumulative exposure to certain chemicals. Use of products containing known skin irritants that can predispose to allergic reactions.

Key Symptoms: Red, inflamed skin at the contact site. Itching and burning sensations on affected areas. Swelling or edema of the skin. Formation of blisters, which may ooze or crust over. Dryness, scaling, or peeling of the skin. Possible development of dark patches or discoloration after healing.

Diagnosis Path: The diagnosis of allergic contact dermatitis due to cosmetics involves a detailed medical history and physical examination. Patch testing is the standard diagnostic procedure, where small amounts of common allergens are applied to the skin under controlled conditions to identify specific sensitivities. A healthcare professional will interpret the results to confirm whether a cosmetic ingredient is responsible for the allergic reaction. Additional tests or elimination of suspicious products may be recommended to verify the diagnosis.

Treatment Protocols: Management primarily focuses on avoiding known allergens and minimizing skin contact with triggering substances. Symptomatic relief can be achieved with topical corticosteroids or antihistamines to reduce inflammation and itching. Skin care routines involving gentle cleansing and moisturization can help restore the skin barrier. In persistent cases, a healthcare provider might recommend alternative products free from common allergens. Long-term strategies include identifying specific sensitivities through testing and avoiding products containing those allergens to prevent recurrent episodes.
