Navigating the Intricacies of Nevus in the Cosmetology Practice: An In-Depth Review


Nevus, commonly referred to as a birthmark, is a complex and often misunderstood dermatological condition. This term denotes various types of skin irregularities present at birth or developing shortly after. As skilled intermediaries between clients and the medical world, cosmetologists play a crucial role in understanding and navigating the intricacies of nevus. This comprehensive review aims to deepen our understanding of nevus, its implications in the cosmetology field, and how professionals can appropriately manage and respond to these conditions.

Navigating the Intricacies of Nevus in the Cosmetology Practice


What is a Nevus?

A nevus, or birthmark, is a broad term for skin abnormalities noticeable at birth or soon after. Nevi can result from overgrowth of structures in the skin, such as pigment cells (melanocytes) or blood vessels. They vary significantly in color, size, shape, and form, and can manifest as pigmented patches, raised bumps, or vascular lesions. Some nevi are temporary, fading away with time, while others persist into adulthood.


Types of Nevus

Nevi are classified into different types based on their characteristics:

Pigmented Nevi

Pigmented nevi are birthmarks resulting from an accumulation of skin pigment cells. Examples include congenital melanocytic nevi, café-au-lait spots, and Mongolian spots.

Vascular Nevi

Also known as vascular birthmarks, these are caused by abnormal blood vessels in or beneath the skin. Examples include port-wine stains and hemangiomas.

Implications of Nevus in Cosmetology Practice

While nevi are generally benign, they may sometimes have health implications, which requires a nuanced understanding and approach from cosmetologists:

Identification and Referral

Cosmetologists, as frontline skincare professionals, are often the first to notice changes in a client’s skin, including nevi. Changes in size, shape, color, or texture, or the onset of itching or bleeding in a nevus, can signal a potentially serious condition, such as melanoma. Therefore, cosmetologists must refer clients presenting these changes to a healthcare provider for further evaluation.

Cosmetic Concerns

Some clients may seek cosmetic solutions to camouflage or reduce the appearance of their nevi. Here, the cosmetologist’s role can involve advising on makeup techniques or skincare products that can effectively conceal the nevus. However, it’s essential to clarify that cosmetologists should never attempt to remove or reduce nevi themselves.

Sun Protection Education

Increased sun exposure can darken some types of nevi and raise skin cancer risk. Cosmetologists play a vital role in educating clients about sun protection, recommending the regular use of broad-spectrum sunscreen and protective clothing.


Nevus, or birthmark, is a multifaceted condition with significant implications for cosmetologists. Armed with a deeper understanding of nevi, cosmetologists can help manage cosmetic concerns related to these birthmarks, educate clients on appropriate sun protection, and refer clients to healthcare professionals when necessary. By doing so, they can offer more comprehensive care and valuable advice to their clients.
