Beginner's guide: Sunscreen products

In the Northern hemisphere, summer has made its arrival. To us Nordic dwellers especially, the warm sunlight brings a long-coveted injection of energy and good vibes. The prime time for using sunscreen products. Here, we share some need-to-knows for adding sun protection to your product range.

UV filters

Chemical ingredients that absorb or reflect the sun’s ultraviolet (UV) light are called UV filters. They can block one or both of the two kinds of UV rays: UVA and UVB. Around 30 UV filters are approved for cosmetic use through the EU Cosmetics Regulation and anyone bringing a sunscreen formulation to market must include one or more of them. A combination is generally needed to reach the desired level of protection.

Since UV filters are expensive, higher sun protection equals a higher production price. Our advice is to formulate based on the predicted use - and user - of the product. 

Water resistance

For a stroll in town, there’s likely no need for a very water-resistant formula. However, using one during swimming or sweaty activities keeps your sunscreen in place. It’s also less damaging to the environment if the UV filters stay on your skin until you decide to wash it off in the shower. 


Lotions, creams, sticks, sprays, and mousses. Sunscreen can be created in a variety of formats, each with its advantages and limitations. But, in essence, the best sunscreen is always the one being used. So, let your brand and customer needs lead you to the one that's right for you.


As with any cosmetic product, your sunscreen formulation must be tested to substantiate the applied claims. The UV filtering properties should be confirmed through standardized techniques, both in the lab and on human skin. A product's SPF (Sun Protection Factor) represents the protection against UVB, while UVA-PF is for UVA. For example, SPF 4 blocks 75% of the UVB rays while SPF 30 blocks 97%.

Sunscreen products impact our health and are therefore under special authority control.


Sunscreen decor should include information about the product's level of protection against UVA and UVB radiation. In the EU, your product will fall into one of eight intervals of SPF. For instance, an SPF of 24.9 will still be marked SPF 20 as the next interval starts with SPF 25. 

The minimum ratio of UVA to UVB protection for the EU market is 1:3 and if this is fulfilled the product can also be marked with the UVA symbol. 

User application

To achieve the SPF level stated on the packaging, you should apply an accurate amount of product to your skin. Since the SPF scale is not fully linear with the amount of sunscreen being used, by only applying half of the amount you can end up with an SPF that’s even less than half of the SPF number on the packaging. The amount of sunscreen to be used should be stated on your sunscreen.
