Sun protection In order to counter the harmful effects of the sun, nothing works better than to apply strict measures to provide season-long protection starting at a young age and throughout one’s lifetime. Limiting sun exposure as much as possible is certainly an effective protection measure. However, when contact with the sun is unavoidable or intended, the application of an effective, quality sunscreen is crucial. Opt for a formulation that has a sun protection factor (SPF) of 30 or more and that is suitable for your skin type. Speak to your pharmacist for additional information about sun protection.
