We lose an average of 1% collagen per annum with ageing, so it’s great to know that with Healite II LED-low level light therapy (LLLT) it’s possible to turn the clock back by stimulating collagen production. By stimulating the fibroblast cells in the deeper layers of your skin, the LED LLLT with Healite has been scientifically shown to improve both collagen and elastin levels by as much as 8 to 12 years in some people.
