Containing mainly antioxidants, the solar preparers protect against free radicals induced by solar radiation. Their content in carotenoids, orange-yellow pigments, also allows you to acquire a faster and longer-lasting tan. They may also be of benefit to people who suffer from mild summer lucitis, a sun allergy especially common in young women. But, in any case, these solar preparers do not dispense with the use of sun protection: we can not do without a cream to index high as soon as you expose yourself.
