Cosmetic Allergies: Use of Patch Testing and Molecular Diagnostics to Identify Allergic Responses.

چکیده اصلی

I investigated the key causes and mechanisms of skin sensitization, evaluated existing diagnostic methods, and proposed new strategies to reduce the risk for allergic reactions. My research focused on sensitization to cosmetic components, including synthetic fragrances, preservatives (i.e., methylisothiazolinone, chlorphenesin), and natural extracts. I used patch testing and molecular diagnostics based on pro-inflammatory markers (i.e., interleukin-6, tumor necrosis factor-alpha). Positive reactions occurred in 69.2% of participants, with synthetic fragrances (51.7%) and methylisothiazolinone (39.2%) as the most common allergens. Women aged 30-45 showed higher susceptibility to severe allergic responses. The study confirmed the effectiveness of patch testing and molecular diagnostics in accurately detecting and predicting skin allergies. Based on the findings, I recommend stricter regulation of sensitizing agents in cosmetics, the introduction of hypoallergenic alternatives, and a shift toward personalized product formulation. The results of my study also highlight the need for updated diagnostic standards, including non-invasive techniques and expanded molecular analyses as well as the revision of regulatory frameworks to enhance cosmetic safety and consumer well-being. Expanding professional knowledge in allergy diagnosis and prevention is essential for raising the standards of care and protecting the health of users.
