What is the medical term for freckles?

The correct answer is lentigines, as this term specifically refers to small, brown spots that can develop on the skin, often as a result of ultraviolet (UV) exposure. Freckles are essentially a type of lentigo, characterized by their flat nature and tan to brown color. They occur when melanocytes, the cells responsible for pigment production, become more active in certain areas of the skin.

Understanding the classification of skin manifestations is essential in esthetics, as it helps to identify different skin types and conditions accurately. Knowing the term lentigines allows estheticians to communicate effectively with clients and other professionals regarding skin concerns related to pigmentation. Additionally, recognizing the difference between lentigines and terms like macules, patches, and nevi broadens the understanding of skin anatomy and pathology, which is crucial in providing informed skincare recommendations and treatments.

Macules refer to flat, discolored spots on the skin that are smaller than lentigines; patches are larger areas of discoloration that may not have the same characteristics as lentigines. Nevi, commonly known as moles, are typically raised and have a different structure altogether. Understanding these distinctions enhances an esthetician's capability to assess skin conditions accurately.
