Contact dermatitis is the type of rash caused by an allergic reaction. This condition occurs when the skin comes into direct contact with an allergen or irritant, triggering an immune response that leads to inflammation, redness, and itching. The rash can vary in severity and may appear as red, swollen patches that may blister or peel, depending on the individual and the extent of the exposure.

Understanding contact dermatitis is essential for estheticians, as it can significantly impact a client’s skin health and well-being. Recognizing the signs and symptoms allows professionals to provide guidance on avoiding certain products or ingredients that may cause an allergic reaction.

In contrast, atopic dermatitis is a chronic condition often associated with genetic factors and is related to other allergies but not specifically from direct contact with an irritant. Seborrheic dermatitis is linked to oil production and yeast overgrowth on the skin, and psoriasis is an autoimmune disorder that speeds up skin cell turnover, resulting in scaly patches. Each of these conditions has different causes and symptoms, underlining the importance of accurately distinguishing between them in a professional practice.
