It´s important to keep insisting: the sun must be taken with caution. But not only that. A good hydration is the fundamental step to prepare the skin for the summer. “It is also necessary to be prudent during the first sunny days. We also have to use protective factors with highs, over 30, repeatedly during exposure, especially if we bathe in the sea. ” Give importance and take into account the hours in which we put in the sun, “the best is early morning and late afternoon, avoiding as much as possible the time when the sun strikes more perpendicular on the Earth, during the midday “,

Some tolerated if ASA was added.for reducing skin flushing.

It is not necessary to be exposed to the Sun which lizards. To generate vitamin D, it suffices with the Sun that comes to us indirectly, through reflection.

The obsession to have darker and darker skin is a fashion.

Dear Casandra: vitamin D is produced in the skin by the effect of UVB rays on the precursor. As the same wave lengths that produce Vit D in the skin are that induce Skin Cancer via mutagenesis, it is question of time to get a skin cancer. If a patient is Vit D defficient/insufficient, I recommend him Vit D supplements.

Recently an article published in the Cell Journal questioned whether or not niacinamide’s anti-aging vascular properties (angiogenesis – in mice) could increase cancer risk in humans. They cautioned that more research needs to be done to answer this question. Do you still recommend niacinamide be used before this research is completed?

Dear Emily: Polypodium leucotomos extract is a well known oral photo protector since 30 years ago. I use it in preventing sunburn, melasma, polymorphic sun eruption, and chronic actinic damage, among others.
Thomas B Fitzpatrick, the most famous chairman in dermatology of Harvard University was very fond of this compound, and used it as an adjuvant in PUVA therapy, like also did Pathak, and it showed useful in psoriasis and vitiligo treatment.
There are hundreds of papers about it, that you can find easily in Pubmed, some of them written by Fitzpatrick, Pathak, and Spanish collaborators like Salvador Gonzalez.
My oldest daughter takes it in summer since 10 years ago, to prevent sun damage.
Yours sincerely

Nice suggestions. Omega-3 fatty acid rich foods are highly recommended and if using a sunscreen, I would suggest natural sunscreens particularly the coral reef-inspired sunscreens developed in Australia as these coral reefs survived for many years under the harsh sun.

1. Minimize exposure.
2. Cover exposed skin with UV rated clothing.
3. Stay hydrated.
4. Assess the risk, if you’ve had skin cancer once, you’re more than likely to get it again.

thanks for these valuable information.

do you recommend vitamin B3 twice daily for healthy people even though these vitamins might have adverse effect especially on hormones.

I was shocked by NSAID ability in reducing cancer and I wanna ask is this based on the paper you were referring to or based on experience. Also it’ll be great if you could share the paper link so we could have a look and get to know this relation.

once again thanks a lot for sharing these information

And what about the protective action of having proper Vit D levels in the body? and the fact that the skin can only make Vit D when exposed to sunlight between 10-2 pm? And that skin cancer wasn’t such the huge thing it is now until sunscreens came into the picture?
