The Influence of Blue Light on the Skin

and the Importance of Adequate Protection

In the world of dermatology and skin care, one topic that has gained relevance in recent years is the impact of blue light on our skin . Blue light, also known as 415 nm radiation, is found not only in the sun's rays but also in the light emitted by electronic devices such as smartphones, tablets, and computers.

Recent studies have shown that this radiation can intensify hyperpigmentation and make it last longer , but only in people with skin types III to VI. Surprisingly, it seems that skin types I and II are not affected. This means that dark-skinned people are more affected than those with lighter skin (now that's something new :D ).

Hyperpigmentation, or the darkening of specific areas of the skin, can be exacerbated by exposure to blue light. Existing spots can become more persistent and visible, creating an aesthetic and dermatological problem that many people seek to avoid.

Is it necessary to use sunscreen indoors?

This is a frequently asked question. The answer is that it depends on your skin type and your exposure to sunlight (through windows) and blue light (from screens) .

If you spend a significant amount of time in front of a window, regardless of your skin type, it's important to protect yourself. Although UVB rays can't penetrate glass, UVA rays (which cause sunburn) can.

The best way to protect your skin from the effects of sunlight is through a combination of antioxidants and sunscreen. Antioxidants help neutralize free radicals, while sunscreen prevents damage caused by UV radiation.

And if you spend significant time in front of screens or in artificially lit environments and have skin phototype III to VI (dark skin), it might be wise to consider some form of protection.

Blue Light Protection Strategies and CR Cosmetics Products

The only way to protect your skin from the effects of blue light is with products containing iron oxide . This ingredient has been shown to be effective against visible light, including blue light. It's commonly found in products like makeup and BB creams. The inclusion of iron oxide in these products not only provides a cosmetic benefit but also offers a layer of protection against visible light.

In the CR Cosmetics range, the following products are particularly relevant for those exposed to sunlight and/or blue light and concerned about hyperpigmentation and other skin effects:

1. Mineral Protection BB Cream : An excellent option that evens skin tone and provides coverage, while containing ingredients that can protect against sunlight and blue light. Contains SPF 50.
   
   

2. Invisible Sun Cream : Protects skin from the negative effects of sun exposure. Ideal for daily use for everyone over 3 years old (doesn't sting eyes at all).
   
   

3. Antioxidant Serum : Provides crucial antioxidant defense to combat photodamage.
   
   

4. Depigmenting Cream : Specially designed to address all types of hyperpigmentation (photoaging, melasma, lentigines...)
   
   

These products are effective in providing comprehensive defense against the potentially harmful effects of sunlight and blue light, and in treating the consequences of this exposure.

If you are like this too, you probably need protection 😉
