The skin is the largest organ of our body and plays an important role in our overall health. One of the biggest threats to the health of our skin is overexposure to the sun. Therefore, sun protection is essential. In this article, we will tell you more about the importance of sunscreen.
Why is sunscreen so important?
1. Protection against the harmful effects of UV rays
The sun emits ultraviolet (UV) rays that can be harmful to the skin. There are three types of UV rays: UVA, UVB and UVC. UVC rays do not reach us thanks to the ozone layer. UVA rays penetrate deep into the skin and can cause premature skin ageing, such as wrinkles, sagging and age spots. UVB rays are the main cause of sunburn and can directly damage DNA in skin cells, leading to skin cancer. Sunscreen helps to block both UVA and UVB rays, significantly reducing the risk of skin damage and skin cancer.
2. Preventing premature skin ageing
Sun exposure without protection accelerates the skin's ageing process. This phenomenon results in wrinkles, fine lines, skin sagging and pigmentation. By using sunscreen daily, we can slow down these signs of skin ageing and keep our skin young and healthy for longer.
3. Reduce the risk of skin cancer
Skin cancer is the most common form of cancer worldwide. Regular use of sunscreen can help reduce the risk of developing skin cancer, including melanoma, the most deadly form of skin cancer. This is especially important for people with fair skin, a family history of skin cancer or those who spend a lot of time outdoors.
Different types of sunscreen products and their uses
There are several types of sunscreen available, each with their own unique properties and applications.
These are the most common types:
1. Chemical sunscreen products
Chemical sunscreen products contain ingredients such as oxybenzone, avobenzone and octocrylene that absorb UV rays and convert them into heat, which is then released through the skin. These sunscreen products are often lighter and less visible on the skin, making them suitable for daily use under make-up or for activities where you sweat a lot, such as sports.
2. Physical (mineral) sunscreen products
Physical sunscreens, such as those containing zinc oxide and titanium dioxide, work by physically blocking and reflecting UV rays. They start working immediately after application and are less irritating to the skin, making them ideal for people with sensitive skin or for children. These agents often have a thicker, whiter consistency, but there are now also formulations available that are less visible on the skin.
3. Water-resistant sunscreens
These sunscreen products are specially designed to provide protection during water activities or heavy sweating. It is important to remember that ‘water-resistant’ does not mean completely waterproof; these products still need to be reapplied every two hours, especially after swimming or drying off with a towel.
4. Sunscreen for face and body
The skin on our face is more sensitive and often oilier than the skin on our body. That is why specific sunscreens have been developed for the face, which are often lighter and less comedogenic (pore-clogging). Body sunscreens tend to be thicker and come in larger packs for extended application.
5. Tinted sunscreen
Tinted sunscreens not only provide UV protection but also add colour to the skin, which can help even out skin tone and hide blemishes. These are perfect for everyday use and can form a light make-up base.
Sun protection is an essential part of a healthy skincare routine
By using sunscreen, we can protect our skin from the harmful effects of UV radiation, delay skin ageing and reduce the risk of skin cancer. With the many types of sunscreen available, there is always a product to suit your specific needs and lifestyle. Remember to apply sunscreen every day, whatever the weather, and reapply regularly to keep your skin optimally protected.
