What precaution should be taken to avoid developing contact dermatitis?

The correct choice emphasizes the importance of limiting exposure to irritants as a precaution against developing contact dermatitis. Contact dermatitis is a skin condition that arises when the skin comes into contact with certain substances, leading to an inflammatory response. By reducing exposure to known irritants, such as harsh chemicals, soaps, and frequent water exposure, one can significantly decrease the likelihood of triggering this condition.

Maintaining a barrier between the skin and potential irritants plays a crucial role in skin health, especially for nail technicians who may regularly handle various products and materials in their work. Minimizing direct contact with these substances helps protect the skin, allowing it to recover and remain healthy over time.

Using hand lotion and wearing cotton gloves can provide additional protection but are secondary measures. Soaking hands in water could potentially exacerbate the problem by weakening the skin barrier and increasing exposure to irritants. Therefore, focusing on limiting contact with irritants directly addresses the root cause of contact dermatitis, making it the most effective precaution.
