Did you ever read the book /Freckle Juice/ by Judy Blume? The story is
about a boy who buys a recipe to grow freckles — with disastrous results!

Not everyone is as excited about having freckles. In fact, we hear from
kids who want to know how to get rid of their freckles. But there's no
magic potion that removes them.

-No Teasing!-

Kids tell us that they don't like being teased about their freckles, so if
you know people who have freckles, please don't make fun of them!

Let's find out what freckles are and why some people have them.

Freckles are not harmful or the sign of a health problem. They're just
pigment cells (cells that contain color) that are contained within the skin
in small batches. Freckles are usually tan or light brown, flat, and very
small (smaller than the head of a pin). Sometimes they overlap and

*Freckles* are clusters of concentrated melanin which are most often
visible on people with a fair complexion. A freckle is also called an
"ephelis". Freckles do not have an increased number of melanin producing
cells (melanocytes). This is in contrast to lentigines and moles.^[1]

Freckled women. Freckles cover the face, chest and shoulders.

Freckles can be found on anyone no matter their genetic background;
however, the amount of freckles is genetic and is related to the presence
of the melanocortin-1 receptor MC1R gene variant.^[2] 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.

Freckles are predominantly found on the face, although they may appear on
any skin exposed to the sun, such as the shoulders. 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.
Their intensity can be altered with citric acid. Freckles are not a skin
disorder, but people with freckles generally have a lower concentration of
photoprotective melanin and are therefore more susceptible to the harmful
effects of UV-radiation. It is suggested that they avoid overexposure and
use sunscreen.^[3]^[4]
