I've read in Ayurveda that there's a form of therapy that goes by the name of 'Suryakiran Chikitsa' (color therepy). The thing that is life giver can't harm you. So, those who have problems with the sun, I suggest they follow ayurveda and understand their body types so as to find what's required to be corrected. Once corrected completely, your body will tolerate the Sun as easily as many people do. In my entire life, I've never ever used cosmetics. Even the day I got married, I prepared natural pastes or creams to be used on body.
