Sun protection guidelines emphasize SPF, UVA and UVB advice in Serbia, Slovenia

Health experts advise that sunscreen with a Sun Protection Factor (SPF) measures protection against UVB rays, which cause sunburn, while broad‑spectrum products also block UVA radiation that contributes to premature skin ageing and skin cancer. Higher SPF numbers offer only a modest increase in UVB blockage; for example, SPF 30 blocks about 97 % of UVB, whereas SPF 50 blocks around 98 %. Authorities recommend using broad‑spectrum sunscreen with at least SPF 30 (or preferably SPF 50), applying it generously to all exposed skin, and reapplying every two hours or after swimming or heavy sweating. Children’s skin is especially vulnerable, and frequent sunburns in childhood raise the risk of melanoma later in life. Protective measures also include wearing hats, sunglasses and shade during peak sun hours.

Both Serbian and Slovenian publications stress selecting fragrance‑free, water‑resistant formulas and choosing products that contain additional skin‑care ingredients such as niacinamide, ceramides or hyaluronic acid for added benefits. Consistent daily use, even on cloudy days, is highlighted as a key strategy to reduce skin damage and the likelihood of skin cancer.
