Using sunscreen is important, yes. But… do you really know what you're protecting yourself from and what you're defending yourself against? Not all sun rays are the same, nor do they affect the skin in the same way. Some cause sunburn, others accelerate aging, and there's even radiation that affects you even when you're not outdoors.
Therefore, understanding the differences between UVA, UVB, HEV (blue light) and IR (infrared radiation) It is key to taking care of the skin in a complete, real and lasting way.
UVA vs UVB: Which is which?
Both UVA and UVB are types of ultraviolet radiation, but their effects on the skin are very different:
UVA rays
- They represent 95% of the UV radiation that reaches the Earth.
- They are present all day, all year round, even when it is cloudy.
- They penetrate deep into the skin, reaching the dermis.
- They are primarily responsible for photoaging , spots, wrinkles and long-term cell damage.
UVB rays
- They represent only 5% of UV radiation.
- Its intensity varies depending on the time of day, the season, and the altitude.
- They mainly affect the epidermis, the outermost layer of the skin.
- They are responsible for the sunburns and damage to the DNA of skin cells.
What if you're indoors?
Being indoors does not guarantee protection. Although many people believe it, skin remains exposed even in enclosed spaces.
- UVA rays penetrate windows , which means they continue to affect the skin even without direct sun exposure, causing photoaging, spots, wrinkles, and cell damage.
- The Blue light (HEV) , emitted by mobile phone screens, computers and LED lights, It can penetrate as far as the dermis and contribute to the formation of blemishes, premature aging, and loss of elasticity.
- The infrared (IR) radiation , although invisible, causes oxidative stress in the skin and accelerates inflammatory processes that damage collagen and promote the appearance of wrinkles and sagging.
That's why, Protecting your skin is also necessary at home, in the office, or even on cloudy days .

What type of sunscreen should I choose?
