An extended exposure to blue light emitted by these gadgets leads to skin irritation, says Yasuke Saito, director of DSM’s personal care and aroma ingredients for Asia Pacific.

Studies show that indoor and artificial blue light from smartphones, computer and other screens can reach up to 80 per cent of the intensity of the blue light found in natural outdoor sources. Blue light is part of the light spectrum found next to ultraviolet (UV). DSM is currently a leader in UV filters for various products.

Saito said there are now many UV protection products, and blue light filters are likely to be the next skin-care products to be made available in the market, using ingredients developed by DSM.

Among the potential products are a day-care lotion or formula in a spray form to help prevent blue-light damage. In addition to electronic gadgets, LED lighting is a source of blue light, and can stimulate production of the skin’s melanin pigments. According to research, Asian people’s skin is more reactive to blue light, resulting in faster ageing and more wrinkles. Asia has become a major market for skin-care products. The world market is estimated to be worth US$90.9 billion (Bt2.97 trillion) by 2022. In Thailand, the market is estimated to be growing at an annual rate of over 5 per cent, especially for skin whitening products.

Few blue-light skin-care products are currently available, with the demand expected to pick up in the next few years due to the effects of blue light exposure, especially in Asian countries where urban stress and extended hours in the office lead to more pollution of skin.

At this stage, the company estimated that the phenomenon affects 50 per cent of the Southeast Asian population.
