Biotherm's first anti-fatigue concentrate for women with dull and de-vitalised skin. This innovative and potent serum harnesses an unparalleled level of a fresh and very active compound called Sulforaphane, derived from Broccoli. Skin.Ergetic Repairing Concentrate is activated at first use and blends the ultra-effective Broccoli Extract with the superior ingredients in the lightweight serum. This fresh technology makes it possible to add the active ingredient to the serum formula at the very last minute so that it offers maximum effectiveness for three months. Once activated the concentrate visibly reduces the appearance of tired looking skin, leaving it radiantly fresh looking all day long! Brand: Biotherm. Size: Travel Size.
