What can cause an allergic reaction resulting in dermatitis?

Fragrances are known to be a common cause of allergic reactions leading to dermatitis, specifically contact dermatitis. Many personal care products, including lotions, creams, and perfumes, contain various synthetic or natural fragrances that can irritate the skin or trigger an immune response in sensitized individuals. This response may manifest as redness, itching, swelling, or rash, typical symptoms of dermatitis.

In contrast, while alcohol can cause skin dryness or irritation, it is less likely to cause an allergic reaction that leads to dermatitis. Sunscreens can sometimes cause irritation due to other ingredients, but not all formulations do. Antibiotics may impact the body in various ways, but they are not typically associated with causing contact dermatitis through allergic reaction to skin application. Thus, fragrances are the most direct agent linked to allergic reactions resulting in dermatitis.
