What is blue light and digital aging?

​

Blue light is also called high-energy visible light (HEV). It penetrates our skin deeper than UV rays. It is emitted by all screens of digital devices such as TVs, mobile phones etc., but is also present in daylight. It triggers oxidative stress as well as DNA and cell damage in the skin and thus causes premature skin ageing, so-called digital ageing.

​

Why is blue light “bad” for my skin?

Blue light is part of UV light. In naturally occurring amounts, it does not have a negative effect on our skin. But since we are increasingly exposed to ever more screen light, we see a “surplus” of blue light, which may be harmful to our skin. It furthers the development of free radicals and – like UV radiation – can cause premature skin ageing, skin irritation as well as DNA and cell damage.

​

• Free radicals are a by-product of our metabolism. But external influences such as the above- mentioned blue light, UV radiation, alcohol and cigarette consumption, lack of sleep and stress also promote their development. These molecules can react with healthy body cells, resulting all kinds of damage. Often, the body’s own protective mechanism no longer suffices. Free radicals cause inflammation, skin irritation and redness, and they accelerate the process of ageing. This is called oxidative stress.

​

• Antioxidants ward off free radicals in the body by preventing the process of oxidation in the body. Antioxidants occur naturally in the body or are absorbed through a balanced diet. However, in order to supply the skin with enough antioxidants to prevent premature ageing, a facial care product such as LR ZEITGARD BLUE LIGHT DEFENDER is recommended, as this provides the skin with additional antioxidants.

​

How does the LR ZEITGARD BLUE LIGHT DEFENDER serum work?

​

The BLUE LIGHT DEFENDER Serum is an intelligent serum that offers the ultimate all-round skin protection against digital ageing with a unique triple action effect:

​

• Reflection: The colour pigment phycocyanin contained in the spirulina extract absorbs the blue light and reduces the high-energy light rays by reflecting them like a protective shield – for comprehensive protection against premature skin ageing and skin irritation.

​

• Radical scavenger: Blue lotus extract is an effective radical scavenger and thus combats oxidative stress – for a youthful and radiant complexion.

​

• Repair: The enzyme photolyase contained in the spirulina extract repairs any cell damage to the skin that has already been caused by exposure to blue light and thereby prevents the formation of premature wrinkles – for a significant reduction in existing wrinkles.

​

When and how do I use LR ZEITGARD BLUE LIGHT DEFENDER Serum and which LR products should I combine it with?

​

• Evenly apply one blob of the serum to your cleansed face every morning. After roughly one minute,

  your skin will have absorbed the serum, and you can continue with your usual LR skincare
  routine on top of the serum. For your daily facial skincare, we recommend LR ALOE VIA Aloe Vera Multi-Active Day Cream, LR ZEITGARD Beauty Diamonds, LR ZEITGARD Nanogold or LR ZEITGARD Platinum Day Cream, depending on your skin’s needs.

​

• As the BLUE LIGHT DEFENDER Serum is a serum, it should not be used as your only
  facial skincare product. The serum forms an effective protective shield against digital ageing and is the perfect basis for your daily facial skincare routine. Apply your day care products after the serum in order to give your skin all the pampering it needs.

​

• Since we are generally not exposed to blue light during the night, we recommend you use a different serum before going to bed, e.g. Serox Instant Result Serum or the firming and moisturising LR ZEITGARD Racine Collagen Serum before you apply your night cream.

Who should use the BLUE LIGHT DEFENDER Serum?

​

Everyone! Because every day, everyone is exposed to blue light and external environmental influences that lead to oxidative stress. Especially people who work at computer screens and use mobile phones and digital devices.
