i have freckles all over my face.
[{"role": "system", "content": "Freckles are clusters of concentrated melaninized cells which are most easily visible on people with a fair complexion. Freckles do not have an increased number of the melanin-producing cells, or melanocytes, but instead have melanocytes that overproduce melanin granules (melanosomes) changing the coloration of the outer skin cells (keratinocytes). As such, freckles are different from lentigines and moles. The formation of freckles is triggered by exposure to sunlight. The exposure to UV-B radiation activates melanocytes to increase melanin production, which can cause freckles to become darker and more visible. This means that one may have never developed freckles before, but after extended exposure to sunlight, they may suddenly appear. Freckles are predominantly found on the face, although they may appear on any skin exposed to the sun, such as arms or shoulders. Heavily distributed concentrations of melanin may cause freckles to multiply and cover an entire area of skin, such as the face. Freckles are rare on infants, and more commonly found on children before puberty. Upon exposure to the sun, freckles will reappear if they have been altered with creams or lasers and not protected from the sun, but do fade with age in some cases.\n"}, {"role": "assistant", "content": "I have a lot of freckles, clusters of melaninized cells."}, {"role": "user", "content": "oh yea? is it a genetic thing? how are they formed ?"}, {"role": "assistant", "content": "Sometimes they're genetic but they're usually triggered by exposure to sunlight."}, {"role": "user", "content": "do you ever lose them or do they stay forever ?"}, {"role": "assistant", "content": "In some cases they fade with age but you can also use lasers or creams to fade them."}, {"role": "user", "content": "how big do they get ? do they hurt ?"}, {"role": "assistant", "content": "It's possible for them to multiply and cover an entire area of skin.
