How much sunscreen do I need to apply?
Use a fingertip amount for the face and half a palm amount for the body.
How long before sunbathing do I apply my sunblock?
The sunscreen needs 30 minutes to develop its full effect. Apply it accordingly before sunbathing. Particularly exposed areas such as the face, cleavage, neck and hands require particularly intensive sun care. Renew your sunblock at least every three hours, more often in the midday heat.
What is the difference between physical (organic) and chemical sunblock?
Physical protection from the sun forms a thin protective layer on the skin and reflects the sun's rays, while chemical sunblock absorbs and neutralizes the sun's rays.
What are the advantages of a physical sunblock?
Physical protection from the sun is usually hypoallergenic and also suitable for children's sensitive skin. It adheres particularly well to the skin, which is why it often "whites", i.e. a white film can be seen on the skin. Titanium dioxide and zinc oxide reflect harmful solar radiation and do not allow it to penetrate the skin in the first place.
What are the benefits of chemical sunscreen?
Chemical sunblock adheres lightly to the skin, is non-sticky and does not leave a white film.
What does SPF and PA mean for sunblock?
The sun protection factor of a sunblock is given in SPF and PA. The SPF (Sun Protection Factor) indicates protection against UVB radiation, which does not penetrate deeply and can cause superficial damage such as painful sunburn and, in extreme cases, skin cancer. The PA or PPD value (UVA Protection and Persistent Pigment Darkening) defines the protection from aging UVA radiation. UVA rays penetrate deep into the skin layers and are responsible for the development of wrinkles and age spots. The PA value of a suncream indicates how much longer the skin needs to tan compared to unprotected skin. PA++ means the skin can be exposed to the sun up to 8 times longer than unprotected without becoming darker. With PA+++ it is up to 16 times longer, PA++++ means 17 times longer and more than without protection.
