Objectives: Cosmetic contact dermatitis (CCD) is an increasing concern due to the rise in aesthetic procedures. Both irritant and allergic reactions may mimic post-procedural effects, complicating diagnosis. Common allergens include fragrances, preservatives, HEMA, lidocaine, and acrylates. Injectable agents like botulinum toxin, hyaluronic acid, and hyaluronidase can cause hypersensitivity, including rare anaphylaxis. Patch testing helps diagnose allergic CCD. Awareness and prevention, including ingredient screening and patient education, are key for safe cosmetic practices.
