A good sunscreen protects against both UVB and UVA rays, is easy to apply, causes little irritation and takes effect quickly. Products that are mineral-based (titanium dioxide or zinc oxide) meet all these criteria perfectly.
Broad-spectrum protection (UVB and UVA)
Titanium dioxide and zinc oxide are minerals found in nature. They are used in sunscreens because they are able to reflect UVB and UVA rays from the sun when they reach our skin. This prevents the rays from entering our skin and damaging it.
Protection for sensitive skin
Titanium dioxide and zinc oxide are very gentle on the skin. In fact, they are often used in products intended for children.
Sunscreens made with these minerals are usually a good choice for people with sensitive skin. Make sure to check that the product you’re buying doesn’t contain other substances that may irritate the skin (e.g. parabens or fragrances), or look for mentions such as “for sensitive skin” or “hypoallergenic” on the label.
Today’s technological advances allow us to create mineral-based sunscreens that are more fluid and easy to apply, and that don’t leave a white coating on the skin.
Since mineral-based sunscreens create a physical barrier on the surface of the skin, they take effect instantly. This comes in handy when the kids are eager to go play outdoors!
Regardless of whether they contain a mineral filter (titanium dioxide, zinc oxide) or a chemical filter (e.g. Meroxyl), all sunscreens must be applied generously on the whole surface of the skin that is exposed to the sun, and must be reapplied regularly (every two hours, and after going swimming or perspiring a lot).
