In recent decades, intensive research has been conducted into the benefits and harms of solar radiation for our health. What is often forgotten is that moderate sunbathing and the vitamin D produced by it keep our immune cells optimally fit for defensive tasks. Light blockers help protect us from harmful sun rays and make sunbathing safe. Generally, those who use light protectants can stay in the sun longer without getting sunburned. The SPF (sun protection factor) indicates how much longer one should be exposed to the sun without getting sunburned.
Chemical versus mineral sunscreens
Distinguished purely by their mode of action, there are two types of UV filters in sunscreens: chemical and mineral. Both variants have advantages and disadvantages . Products that contain chemical filters should be applied about 30 minutes before to be fully effective. Most chemical sunscreens contain UV-A and UV-B blockers. UV-A rays age the skin, UV-B burn the skin and UV-C are already filtered in the atmosphere.
- Chemical photoprotectants: Chemical UV filters penetrate the outer layer of the epidermis. After an activation period of about 30 minutes, they begin to convert UV rays in the skin into other forms of energy by means of a chemical reaction. The most common are avobenzone, benzophenone, ethylhexyl or methoxycinnamate. Many of these compounds are potent free radical exciters. When they come into contact with UV light, they are broken down. They generate free radicals that can damage the lipids, proteins and DNA of cells and have been linked to premature skin aging and cancer.
- Mineral sunscreens: At Saint Charles, we recommend sun care that is completely free of synthetic ingredients, chemical photoprotective filters and nanoparticles. Mineral UV filters consist of natural white pigments, most commonly titanium dioxide and zinc oxide. These lay on the skin surface like many small mirrors and immediately start reflecting the sunlight. Good and natural sunscreen consists of an effective combination of plants and minerals. This complex protects the skin without irritating it and, in the best case, nourishes it with plant-based active ingredients and moisture such as aloe vera. Thus, mineral sunscreen is also ideally suited for babies and children.
