Non-invasive radio frequency treatments, applied by an experienced practitioner, that aim to tighten skin on the face and neck. Sun spots. Liver spots. Solar lentigines. No matter what you call them, those flat gray, brown, and black spots on the skin come from the same place: space. Specifically, the sun. All skin color is the result of a pigment called melanin produced in the epidermis. Each person’s skin produces melanin at certain rate, but ultraviolet rays from the sun accelerate that process, which creates a darker, tanned appearance. Over years, melanin can become particularly concentrated in one area and clump together to form age spots, typically on the hands, face, shoulders, and other areas regularly exposed to sunlight. Freckles are produced through a similar process, but their formation is much more strongly predicted by genetics.
