What to look for when choosing a sunscreen?

The arrival of summer is a challenge for the whole body. This year, the first heat has already given us a taste. When it’s hot, muggy remember to take in plenty of water! It’s a good idea to take care of headgear to protect yourself from stroke, and protect your skin with sunscreen. There are plenty of them on the market. What to look for to choose the best one for you?

The first thing we should pay attention to when choosing a sunscreen product is UVA and UVB protection. These are two types of radiation that affect our skin differently.

UVA accounts for 95% of the radiation reaching the Earth. It does not change regardless of the season. It represents the main reason for which we should use sun protection throughout the year. Unlike UVB, UVA does not produce immediately visible effects on our skin. However, by penetrating through the epidermis all the way to the dermis, it causes much more damage. It destroys the cells that produce collagen and elastin. By failing to protect the skin, we can be sure that the signs of aging will appear much sooner than they should, and with them, limpness and grayness.

UVB is the biggest problem in summer. It is UVB that is responsible for tanning, but also for erythema and burns. During the summer season, it is recommended to avoid sun exposure between 10 am and 3 pm.

SPF – what does it mean?

SPF – or Sun Protect Factor – is a factor that tells consumers how long we can safely be in the sun before unwanted erythema appears. We recommend using high SPF protection, although there are three grades available on the market:

Low protection: SPF 6-10
Medium protection: SPF 15-25
High: SPF 30-50+

SPF50+ is the highest level of protection possible with the cream. If you happen to find a cosmetic product promising 100% protection… we advise you to think twice.


The material of the jeans has a protection factor of 80. If the material of the jeans does not provide full protection, how could the cream achieve such a result? This is impossible.

Blue Light

When choosing a sunscreen, we recommend going for products that offer protection against all types of radiation. A few years ago, UVA and UVB protection was sufficient to call the product effective. Today, it is known that blue light emitted from the screens of electrical devices (smartphones, laptops, televisions) poses an even greater threat than UVA and UVB. It penetrates deeper than UVA and wreaks even more havoc on the tissues.

Mineral or chemical filter?

Mineral filters are considered to be gentler both for our skin and in their protective effect. They have more natural compositions, but unfortunately, because of this, they often work less well and for shorter periods of time. They mainly focus on reflecting the sun’s rays, absorbing them and turning them into heat.

Chemical filters provide more effective protection. They work for a longer period of time, but it is recommended to wait about half an hour after applying the cream, before going out in the sun. During this time, the cream will be absorbed, and the active ingredients in it will begin to work.


When deciding on a chemical sunscreen, pay attention to whether it contains oxybenzone or octinoxate. These substances are a common component of chemical filters with a high risk of toxicity.


City SUN is a cream for daily use, designed for people who live fast. Thanks to its lightweight texture, the cream is quickly absorbed and leaves no white residue, and is an excellent base for makeup. It provides protection against UVA, UVB and Blue Light. It can also replace a day cream due to its moisturizing properties.
