What should I pay attention to sunscreen?

zonnebrand creme kiezen

Now the summer there is and we are more often outside it is good to know what to look out for when purchasing a sunscreen. What do you pay attention to your purchase?

UV radiation

On the beach, the sunlight is bright and the water also reflects your radiation. If the skin is exposed to UV rays too long, they can cause skin aging and DNA damage. Good protection against both UVA and UVB rays is therefore necessary. Yet it remains difficult to choose a good product.

Sun filters

My customers have regularly asked me if I develop products with sun filters. After I immerse myself in the scientific literature I decided not to do that. At aurora dionis Dermacosmetics are in front of skin-friendliness and environmental friendliness. With the existing options for sun filters, they are not fully guaranteed in my experience.


Types of filters

At first glance, the names of the different types of sun filters are rather confusing. A chemical filter is also called organic because there are carbon compounds. Organic so do not refreicate to organic or natural, but to the branch of chemistry that deals with organic connections.

Chemical filters

Chemical filters absorb ultraviolet rays. Examples are benzophenone, avobenzone, octocrylene and methoxycinnamate. A disadvantage of chemical filters is that they can penetrate the upper skin layer and can cause irritation. Moreover, they are not good for the environment. Benzophenone is known to affect the coral.


Physical filters

Opposite the chemical filters are physical or mineral filters. These are 'real' natural filters. At least, if you define 'natural' as the counterpart of synthetic, namely substances that have undergone few chemical operations.
A physical filter places a layer on the skin that refers to sun rays. Examples are of mineral filters are titanium dioxide and zinc oxide. If the particles are not smaller with the help of nanotechnology they only give a white haze on the skin.

Although physical filters are less irritating to the skin, they can also be bad for the environment. That risk is greatest to swim, when the entire body is inched. During winter sports, only face protection needs the sun.

Own experience

I use as little sunscreen as possible. In the summer I stay in the shade on the hottest hours of the day and the rest of the day I wear thin clothes and a hat. I am longer in the sun, I lubricate my face with a physical filter. That gives a white haze, but I'd rather have that an irritation of my sensitive skin.
