Phototherapy is the use of light in treatment of a condition.
Red and Near infrared lights are well evidenced to improve pigmentation. Particular strengths of Near infrared and Red light therapy can improve pigmentation. It works by stimulating cells through the Mitochondria (The power house of the cell). This can help them produce more adenosine triphosphate (ATP), which is the energy source for all cells. By improving cellular energy, cells repair themselves more quickly, and can therefore help improve hyperpigmentation.
Please remember, that it is particular strengths of wave lengths which have been well evidenced and researched which will cause improvements in the skin - NOT the cheap light masks which you can buy online. These are unlikely to have the correct wave lengths and also contain a multiple of other colours which have NO evidence to support that they work.
Here at SkinLab we have 2 Dermalux LED phototherapy devices which are Medically Licensed and CEA approved. These devices can be rented via our home rental scheme for a period of 2 weeks.
It is recommended it is used daily for at least 2 weeks.
