Tips to combat screen-induced damage

Inflammation: Blue light exposure can trigger inflammation by disrupting your skin’s barrier and causing irritation. This inflammation can exacerbate conditions like acne, rosacea, and eczema.

Disruption of skin barrier: Your skin barrier, which protects you against environmental aggressors and retains moisture, can be compromised by blue light. This disruption can lead to increased dryness, sensitivity, and a compromised ability to repair and regenerate.

How do I protect my skin?

Given the very intrusive presence of screens and blue light in our environment, it’s crucial to adopt protective measures to safeguard your skin. Here are my top recommendations:

Use sunscreen daily: Choose a broad-spectrum sunscreen that offers protection against both UVA/UVB and blue light. Look for ingredients like zinc oxide, titanium dioxide, and iron oxides, which can provide a barrier against blue light.

Incorporate antioxidants into your skincare routine: Antioxidants such as vitamin C, vitamin E, niacinamide, and ferulic acid help neutralise free radicals generated by blue light exposure. Using serums or moisturisers containing these ingredients can bolster your skin’s defence.

Screen time management: Limit your screen time wherever possible and take regular breaks using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This not only helps reduce eye strain but also minimises prolonged blue light exposure to your skin.

Use screen protectors: Invest in screen protectors that filter blue light. These are available for most smartphones, tablets, and computer screens, and can significantly reduce the blue light exposure your skin is exposed to.

Maintain a healthy skincare routine: A consistent skincare routine that includes cleansing, moisturising, and regular use of sunscreen is essential. Ensure you’re hydrating your skin adequately to maintain a strong skin barrier.

Wear protective clothing: Always wear protective clothing. If you spend a lot of time in front of screens, consider wearing clothing that covers more skin, especially on your arms.

Use blue light-blocking glasses: These glasses are designed to filter out blue light and should be added to your daily routine.

Incorporating the above measures into your skin care can help you signifcantly reduce the risk of blue light-induced skin damage.
