Complexion refers to the natural color, texture, and appearance of the skin, particularly on the face. It is influenced by various factors, including genetics, age, and environmental conditions. A person's complexion can range from fair to dark and may have undertones such as warm, cool, or neutral. Different skin types, such as oily, dry, combination, and sensitive, can affect complexion. Additionally, factors like sun exposure, diet, and skincare routines play a significant role in maintaining a healthy complexion. Understanding one's complexion can help in choosing appropriate skincare products and treatments.
