Day cream with SPF? perfect for the spring?
Day cream with SPF? is this the perfect idea to accompany us through a spring day?
Day creams with UV protection are now offered by almost every cosmetics manufacturer. Great, because who wants to use daily sunscreen, even though the spring sun is still behind clouds and we spend the day in front of the computer? But we know that protection against the sun's rays is essential in the fight against skin cancer and wrinkles. And that's why it seems so logical to cover the skin with a light protection every day. But is that really a good idea?
Face creams with UV protection contain quite controversial ingredients. Your filters namely. In addition, we can not dose them so that the promised protection is actually kept!
Why is day cream with SPF (SPF) in the criticism?
- The UV filters of day creams with sun protection factor are suspected of acting like hormones. According to Margret Schlumpf, environmental toxicologist from Zurich, the filter substances can enter the body. They were even detected in breast milk. Smurf warns that we know too little about how these filters work in the body. Further investigations have traces of the filter in the Urine, blood plasma and sperm demonstrated.
- Another negative point: some creams contain PEG / PEG derivatives. These are suspected to make the skin more permeable to foreign substances.
- In some creams can be found organohalogen compounds, These are suspected of acting allergenic.
- Six products were also positive aluminum tested. The amount is still within the guidelines.
- In addition, the effect is doubted. For full sunscreen, an adult needs two milligrams of cream per square centimeter of skin. For the face you need about a teaspoon. But you do not usually use that much face cream. Does the filter bring anything at all?
With or without? What does the dermatologist recommend?
But is not a sunscreen day cream ideal for preventing wrinkles? Smart is to adjust the sun protection of the season. In summer you need a much higher level of protection than in winter. First apply a day cream without SPF and then adjust the sun cream of the season, the skin type and the daily schedule. And: Very low sun protection factors bring nothing at all - here you can definitely save the filter.
Also Prof. Dr. Volker Steinkraus, Head of the Dermatologicum Hamburg, emphasizes to ChroniquesDuVasteMonde.com:
"If you work indoors, you do not need UV protection in your day cream - if at all, UVA protection would be relevant to a window workstation and no UVB protection, as in most day creams, because only UVA rays penetrate I emphasize for many years that the usual day creams should be UV-protection-free. "
Basically, experts advise mineral filters are preferable to chemical ones, The whitening effect was improved on most products. However, when mineral filters do not whitewash, they are mostly nano sized. However, this has to be declared on the packaging since 2013.
