What is the role of the pharmacist, then? You should advise the user or discourage it ? Ana Maria Molina Ruiz, dematóloga at the University Hospital Fundación Jiménez Díaz de Madrid, addressed this issue during his speech photoprotection: Not only in summer , as part of the first day on dermofarmacia , organized by the COF Madrid at the Ritz Hotel.
- One study found that avoiding the sun increases the risk of death the same as smoking

The expert explained that for a sunscreen is balanced , the relationship between the SPF and PPD index must be less than three, to calculate it, divide the SPF between the PPD, although this is not always indicated.
