What is a common sign of infection in a manicure/pedicure service?

Redness and swelling are indeed common signs of infection, particularly in the context of manicure and pedicure services. When the skin around the nails becomes infected, either from a break in the skin or exposure to bacteria, it often presents with redness as the body responds to the infection by increasing blood flow to the area. This response can also lead to swelling as fluids accumulate in the tissues. These symptoms indicate that there may be an underlying issue that requires attention, such as a bacterial or fungal infection.

In contrast, dryness and flaking typically indicate issues related to skin hydration and may not relate directly to infection. Excessive shine is usually a characteristic of well-polished nails and does not suggest any sort of infection. Uneven nail growth can result from various factors, such as nutrition or trauma, but like dryness and shine, it doesn't directly point to an infection. Recognizing redness and swelling is crucial for cosmetologists, as it helps ensure they maintain a safe and hygienic environment for clients.
