Frequently Asked Questions
Are there clinical studies backing blue light product effectiveness?
Yes, studies have shown that blue light can penetrate the skin and trigger oxidative stress, which contributes to premature aging, hyperpigmentation, and weakened skin barrier function. While the exact extent of damage and the amount of screen time required to cause significant harm hasn’t been fully determined, research confirms that prolonged exposure to blue light can accelerate skin issues. Blue light serums help mitigate these effects by neutralising free radicals and supporting skin repair.
Does it also repair existing blue light damage?
Yes, the serum is formulated not only to protect but also to repair damage caused by blue light. Antioxidants and skin-repairing ingredients help reduce oxidative stress, improve skin texture, and promote even skin tone over time.
Can it be used with devices like LED masks or during blue light therapy?
Yes, the serum can be used alongside LED masks or blue light therapy devices. It does not interfere with the treatments and may even enhance the skin’s ability to recover and stay hydrated.
