The choice between SPF 30 and SPF 50+ depends on several factors, including skin type, sun intensity, and how long you will be outdoors.

Choose SPF 50+ if:

• You have fair and sensitive skin that burns easily and rarely tans.
• You will be exposed to strong sun for longer periods, e.g., at the beach, in the mountains, or in sunny climates.
• It is early in the season and your skin has not yet become accustomed to the sun.
• You have a history of skin cancer yourself or in your family, actinic keratosis, or other skin conditions that make you more sensitive to UV radiation.

Choose SPF 30 if:

• You have a darker skin type that rarely burns and tans easily.
• You spend most of your time indoors and are only exposed to the sun for short periods.
• You have gradually accustomed your skin to the sun and built up a certain natural protection later in the summer.
• You have acne-prone skin and need a lighter texture that doesn't cause breakouts.

For children, we primarily recommend our body sunscreens because the facial products contain ingredients that allow them to replace a regular face cream, such as prebiotics. Children do not need these types of ingredients, so the body products are more suitable for them.

Our sunscreens contain a combination of modern organic (chemical) filters and physical (mineral) filters, to provide broad and effective protection against both UVA and UVB radiation.

Organic filters are soluble (with a few exceptions) substances consisting of carbon-based compounds. They protect the skin by absorbing UV radiation and converting it into harmless energy.

Physical filters consist of small, insoluble particles – primarily zinc oxide and titanium dioxide. They protect the skin by scattering, reflecting, and to some extent also absorbing UV radiation.

The difference between the filter types thus lies in their structure, solubility, and how they interact with UV light. By combining both types, we can optimize protection, stability, and feel on the skin.

Zinc oxide and titanium dioxide are the two approved mineral filters that are often combined to provide optimal UV protection. Together, zinc oxide and titanium dioxide provide very good protection against both UVB and UVA, and also protect against longer UVA wavelengths (340 to 400nm).

Both zinc and titanium dioxide are very photostable and do not react with other UV filters. Smaller particles, known as nanoparticles, also provide better protection against the sun's UV rays than larger particles.

Another advantage of the smaller nanoparticles is that they reduce the white film that mineral filters can leave on the skin. The smaller the particles, the less of a white layer the filter leaves on the skin.

Although nanoparticles are small, they are still too large to penetrate the skin, and much larger than most other substances and UV filters used.

There is an identified risk if the particles are inhaled, and therefore they are not used in spray products, but they are completely safe in creams.

For the face and neck, approximately one teaspoon of sunscreen is needed. For the entire body, about a handful is required. Apply generously to achieve the SPF stated on the packaging and reapply as needed.
