Sun care stated SPF refers only to the product’s ability to filter UVB rays. (Remember—UVA rays cause aging; UVB rays cause burning.) Some products claim to provide “broad-spectrum” protection against both, but the term doesn’t really have any definitive meaning, and some sun care advertised as “broad-spectrum” really aren’t.
In order to be labeled as “broad-spectrum” or to make claims of protecting against cancer or aging, a sunscreen must provide equal protection against UVA and UVB rays and be SPF 15 or higher exapmle UVA/UVB SPF 30. If a sun care has different levels of protection against UVA and UVB rays, it can only carry an SPF that reflects the lowest level of protection. For example, if a product provides SPF 30 protection against UVB but only SPF 15 protection against UVA, the product’s new label must say SPF 15. Any sun care with SPF 14 or lower will be required to carry a warning label stating that it has not been shown to protect against cancer or skin aging.
Don't be fooled by waterproof or sweatproof sun protection,there's no such thing. Actually these are the words that lured consumers into a false sense of security.Sun care can be labeled “water-resistant,” as long as they specify the amount of protection they offer, whether forty minutes or eighty minutes before reapplication, according to the FDA’s standard testing methods. Any sun care that does not label itself as “water-resistant” must now carry a label urging consumers to choose a water-resistant product for swimming or sports.
Skin cancer diagnoses have been on the rise for years, especially among young women. Many dermatologists even report treating patients in their teens and twenties for malignant melanoma and other sun-related cancers. These commonsense changes will help keep us all a little safer, not to mention looking a little younger for a little longer.
High Protection SPF30 Sun-Sensitive areas care
Each person has a 'sunshine capital exposure' determined at birth by their skin type(prototype). This corresponds to the hours of sunshine that you may enjoy during your life without the risk of causing serious damage to your skin. This capital is shrinking over the time and must be maintained daily with a protection adapted to your skin and to sunshine intensity.
Remember to adopt a responsible attitude and to respect certain principles of protection needed:
1-Avoid intense exposure between 12pm to 4pm
2-Look for a shade
3-Wear a hat, sunglasses and a dry T-shirt
4-Regulary hydrates yourself
5-Apply sun cares with an index of protection suitable for your skin type and degree of sunshine
However,the use sun cares does not allow you to stay longer in the sun than recommended, especially during the 'intense exposure' hours of the day. To ensure that the products have a full protective role, remember to apply them in sufficient dose before first exposure, after sweating, swimming or drying yourself, and to reapply every two hours while being exposed. This ensures protection at the level corresponding to the index of protection illustrated.
Sun overexposure can cause serious skin lesions at every age and even more on children. It is recommended that you do not expose babies and young children in the sun.
