You might already be familiar with the idea of shielding your skin from UVA and UVB rays, but have you caught wind of the latest research around blue light emitted from your screens? If your scrolling habits often extend late into the night, you might want to consider these new additions to your skincare routine.
Extended exposure to the sun has long been linked to hyperpigmentation and maturing your skin before its time. However, emerging research now highlights the potential impact of 'blue light' emitted by our devices on our skin's health in the long run.
To shed light on this subject (pun not intended!), we reached out to dermatologist Dr Kiran Sethi, seeking insights into how blue light influences our skin.
Is blue light damage a concern we should worry about?
’In substantial amounts, blue light can trigger inflammation in the skin and eyes, exacerbate hyperpigmentation, and contribute to skin ageing,’ explains Dr Kiran.
However, she reassures us, ’In appropriate proportions and frequency, blue light also boasts anti-bacterial properties that can aid in reducing acne and skin inflammation.’
Dr Kiran suggests three simple yet effective ways to shield your skin against potential blue light damage.
#1. Cut Down Screen Time
Reducing excessive screen exposure directly correlates to minimising potential damage from blue light. Establishing healthy boundaries with your screen becomes crucial. ’Limit your screen usage, especially after 7pm or 8 pm,’ advises Dr Kiran.
#2. Sunscreen: Your Guardian
The year-round necessity of sunscreen takes on added importance now. ’Mineral sunscreens, particularly those containing titanium dioxide and zinc oxide, are most effective in thwarting blue light,’ recommends Dr Kiran. These ingredients provide optimal protection for your skin.
#3. Embrace Antioxidant-Rich Skincare
’Topical antioxidants such as vitamin C, ferulic acid, and resveratrol work wonders for skin affected by blue light exposure,’ notes Dr Kiran. These potent ingredients not only shield your skin, but also aid in rejuvenation, offering dual protection and repair.
Implementing these simple practices into your skincare routine can serve as a shield against potential harm from blue light exposure. It's all about balance, and taking proactive steps to care for your skin in the digital age.
