Skin rejuvenation works in three different ways firstly it can target melanin so very light pigmentation spots if any may flake off within approximately 7 days however please note that this is not a specific pigmentation treatment secondly it targets unsightly blood vessels that can appear with age over the face and lastly it leaves all skin types looking firmer and smoother by stimulating the fibroblasts that create collagen skin rejuvenation therefore gives an amazing overall treatment
