I melanociti sono
delle cellule che
hanno la forma di
piccole stelle
marine.

I più numerosi si trovano nella nostra pelle, hanno il
compito di colorarla per proteggerla… quando viene
colpita dai raggi del sole.
![Page 14: Perchè ci abbronziamo](https://reader031.vdocuments.mx/reader031/viewer/2022030223/5882eca51a28ab3f1e8b4da9/html5/thumbnails/14.jpg)
Questo colore si chiama melanina e determina l’abbronzatura
![Page 15: Perchè ci abbronziamo](https://reader031.vdocuments.mx/reader031/viewer/2022030223/5882eca51a28ab3f1e8b4da9/html5/thumbnails/15.jpg)
Può essere paragonata ad un ombrello che le cellule del nostro corpo, chiamate melanociti aprono quando la pioggia di radiazioni solari colpisce la nostra pelle.
![Page 16: Perchè ci abbronziamo](https://reader031.vdocuments.mx/reader031/viewer/2022030223/5882eca51a28ab3f1e8b4da9/html5/thumbnails/16.jpg)
Questo ombrello non è sempre
resistente perciò, per farlo
diventare un ombrello dai
super poteri è necessario
coprirlo con una polvere
magica, la protezione solare.
In questo modo la pelle ha uno
scudo dai super poteri, non si
scotta e quindi non si
danneggia.

Quando parliamo di fototipi diversi,
intendiamo ad es. quei bimbi
con un colore diverso della pelle,
degli occhi e dei capelli…
La cute si colora in maniera diversa
al sole.
