With a variety of five light treatments, the MZ Skin Light Therapy Golden Facial Treatment Device (£385) should be used regularly — three times a week, according to Dr. Zamani — and for an adequate amount of time. That means wearing the mask for 15-20 minutes every time you use it. Follow these guidelines and the brand promises you'll start to see results in 3 to 4 weeks.
"I also recommending wearing eye masks or closing your eyes while using the LED mask as the light can be rather strong and powerful," said Dr. Zamani. "Make sure that you have consulted your doctor if you are on medication as prolonged exposure to blue or red light may cause damage to the eyes, and do not use if you are epileptic or suffer from migraines."
