Particularités de la pigmentation dans la population “blanche” (Pour les professionnels)

Pigments

There are two types of pigments (melanin) which determine skin colour in caucasians:

• Eumelanin:

1. Has a photoprotective action
2. Acts as a physical and chemical filter to light
3. Absorbs free radicals in response to sun exposure

• Pheomelanin

1. Is found most often in red-haired individuals
2. Has a photoaggressive action
3. Produces free radicals in response to sun exposure

There is a third type of melanin called neuromelanin which is found in the nervous system
