Neutrogena are revolutionising the acne fighting product space on the home front. The new Neutrogena Visibly Clear Light Therapy Acne Mask is a wearable LED device with red and blue wavelengths which move across the skin at the speed of light. This might seem scary, but it really works - the acne cycle is disrupted and after a week of daily 10 minute sessions consumers will see a result. So how does it all work? The blue light kills bacteria while the red light reduces inflammation related to acne. This technology has been used by dermatologists for a long time, although the Neutrogena Visibly Clear Light Therapy Acne Mask is a slightly lower energy level which is manageable for use at home. The treatment consists of a mask and an activator which works for 30 treatments.
