Décolletage Filler explained

The décolletage is the upper chest area below the neck. Sun damage, ageing and side sleeping can cause vertical lines and thin, crepey skin there. Décolletage treatment uses soft filler for the lines and skin boosters for overall skin quality.


How Décolletage Filler works

Very soft hyaluronic acid filler is placed along deeper lines to lift the crease. Skin boosters such as Rejuran or Profhilo may be spread across the area to improve hydration and texture. The skin here is thin, so small amounts and a fine technique are used. HA products can be dissolved if needed.
