Welcome to the Roxane Laser Studio blog. Let's shed some light and tackle a significant factor contributing to skin ageing – the often underestimated impact of UV rays. Did you know that a staggering 60% of skin ageing is caused by exposure to these harmful rays? Protecting your skin from UV rays and blue screen light is more critical than ever, particularly with the impact of climate change.
UV rays and skin aging
Ultraviolet (UV) rays emitted by the sun are a major culprit behind the premature ageing of the skin. There are two types of UV rays that reach the Earth's surface – UVA and UVB. Both play a role in causing damage to the skin, leading to visible signs of ageing.
UVA rays
UVA rays' intensity remains consistent throughout the year, whether winter or summer, penetrating deep into the skin, causing long-term damage. UVA rays are primarily responsible for wrinkles, fine lines, and the loss of skin elasticity.
UVB rays
These rays affect the skin's outer layer and are the main cause of sunburn. UVB rays contribute to the development of dark spots, and uneven skin tone, and can accelerate the ageing process.
The impact of UV rays on skin ageing
Collagen breakdown
UV rays break down collagen, a protein that provides structure to the skin. Collagen loss leads to sagging, wrinkles, and a loss of skin firmness.
Formation of free radicals
UV exposure generates free radicals in the skin, causing oxidative stress. This stress damages skin cells and accelerates the ageing process.
Hyperpigmentation
Prolonged exposure to UV rays can lead to the development of dark spots and uneven pigmentation, giving the skin an aged appearance.
Weakening of skin barrier
UV rays compromise the skin's natural protective barrier, making it more susceptible to moisture loss, dryness, and environmental pollutants.
Protecting your skin is the key to ageless beauty
Now that we understand the detrimental effects of UV rays, it's crucial to prioritise sun protection in our daily skincare routine. Here are some tips to safeguard your skin from the ageing effects of UV rays.
Use sunscreen daily
Apply a broad-spectrum sunscreen with SPF 30 or higher and clinically approved that protects from UVA rays, even on cloudy days. Reapply every two hours, especially if you're spending extended periods outdoors.
Seek shade
Limit your exposure to direct sunlight during peak hours (10 a.m. to 4 p.m.) when UV rays are strongest.
Wear protective clothing
Opt for long sleeves, wide-brimmed hats, and sunglasses to shield your skin and eyes from harmful UV rays.
Stay hydrated
Maintain skin health by staying hydrated from within. Drink plenty of water to support your skin's natural defence mechanisms.
Climate change matters
Climate change is making the sun's rays stronger, which means we need to be even more careful. The changing climate can affect our skin, making shielding ourselves from the sun more important.
Exploring the impact of blue light on skin aging
Research suggests that prolonged exposure to high-energy visible (HEV) blue light may contribute to skin ageing, including wrinkles and fine lines. Blue light can penetrate the skin more deeply than ultraviolet (UV) light and may generate reactive oxygen species associated with oxidative stress and cellular damage.
However, it's important to note that the levels of blue light emitted by screens are typically much lower than those from natural sunlight. The impact of blue light on the skin is still an area of ongoing research, and more studies are needed to understand the long-term effects fully.
To reduce potential risks, consider taking breaks from screen time, using blue light filters or screen protectors, and applying skincare products with antioxidants like Vitamin C or Resveratrol to help protect against oxidative stress. Maintaining sun protection remains crucial for overall skin health.
By following sun safety tips and using sun protection in your skincare routine, you can keep your skin safe and make it look beautiful for a long time.
