Ellipse IPL treatment alone can produce a significant improvement in scar tissue, particularly in the case of surgical or trauma scars. It does this by creating a vascular response in the blood vessels around the scar, which in turn leads to collagen replacement. Ellipse Frax 1550nm laser treatment works by creating very small, very controlled islands of heat damage, surrounded by healthy normal skin. When the body repairs this controlled damage, collagen in the whole of the treated area is replaced, but more neatly than it was before. Research has shown that a combination treatment using Ellipse IPL followed by the Frax 1550 produces an improved result with less treatments.
