Doctors warn of a drastic increase in skin cancer cases, and the Hina Health portal brings key advice on SPF factors and the difference between chemical and mineral filters.
While you enjoy summer pleasures, your skin is waging a silent battle against an invisible enemy. Excessive exposure to the sun's rays without adequate protection is no longer just a matter of aesthetics and premature aging, but a serious health risk. The Hina Health portal relays warnings from numerous dermatologists who emphasize that recent years have seen a drastic rise in skin cancer cases, particularly melanoma.
Although the positive effects of the sun are undeniable, its role in accelerating skin aging and the development of carcinoma cannot be overlooked. UV rays cause oxidative stress and break down collagen and hyaluronic acid, leading to wrinkles and hyperpigmentation. Therefore, the golden rule for all summer months remains the same: be cautious when exposing yourself to the sun and always adequately protect your skin.
The acronym SPF stands for Sun Protection Factor and indicates how much longer you can extend your skin's natural resistance before a burn occurs. This natural protection lasts about 10 minutes. For instance, a sunscreen with SPF 50 theoretically allows you to stay in the sun 50 times longer than without any protection.
However, it's important to note that no SPF provides complete, 100% protection. Even SPF 50 blocks 98% of UV rays. Therefore, especially during peak sun hours, additional protection such as wearing a hat, sunglasses, light clothing, and seeking shade is recommended.
The choice between chemical and mineral UV filters depends on your skin type and personal preferences. Chemical (organic) filters work by absorbing UV light. They are more cosmetically elegant, leave no white residue, and are easier to spread. On the other hand, their main drawback is questionable safety. Some studies suggest these filters can penetrate the skin into the bloodstream and cause health issues, including endocrine disruptions, and they may also cause irritation in some individuals.
Mineral (inorganic) filters, composed of zinc oxide and titanium dioxide, are considered safer because they do not penetrate the skin. They partially absorb and partially reflect and scatter UV radiation. They are ideal for people with sensitive skin, although they often leave visible white marks. Those with dry skin should be cautious, as zinc oxide in formulations can further dehydrate the skin, so it's recommended to apply serums and moisturizers underneath mineral sunscreen.
