What is a condition of the skin that involves blistering or epidermal separation due to lateral pressure of a laser?

Nikolski is a skin condition characterized by blistering or epidermal separation that occurs when lateral pressure is applied, such as in the context of certain dermatological procedures, including laser treatments. This phenomenon is often associated with autoimmune blistering diseases, where the integrity of the skin layer is compromised. The Nikolski sign can indicate underlying conditions that affect how the skin responds to physical manipulation. Understanding this concept is crucial for estheticians as it highlights the importance of careful client assessment and procedure technique to prevent adverse reactions during treatments.

Erythema refers to redness of the skin typically caused by increased blood flow and inflammation, which does not specifically relate to blister formation due to lateral pressure. Eczema is a chronic skin condition characterized by itching and inflammation but does not involve the blistering aspect described in the question. Psoriasis is an autoimmune condition that leads to thickened, scaly patches on the skin, which also does not match the symptoms of blistering or epidermal separation due to pressure. Thus, Nikolski is the only option accurately reflecting the described condition.
