Which of the following is a sign of overexposure to nail enhancement products?

Skin irritation is a key sign of overexposure to nail enhancement products. Many of these products contain chemicals that can lead to irritation when they come into prolonged contact with the skin. This can manifest as redness, itching, or a burning sensation, indicating that the skin is reacting negatively to the substances used, such as acrylics or gels.

In the context of nail technology, understanding the signs of overexposure is vital. If a client experiences skin irritation around the nail area, it's a clear signal that the products may not be suitable for them, or that there has been excessive application or inadequate ventilation during the service, highlighting the importance of adhering to safety guidelines and proper product use.

On the other hand, improvement in nail health, stronger nails, and an increase in nail growth generally reflect positive conditions rather than signs of overexposure. Therefore, they would not be indicative of any negative reactions to nail enhancement products.
