Cafeïne

Cafeïne is een krachtig natuurlijk actief bestanddeel dat op veel problemen kan inwerken. Wallen, donkere kringen, deze tonicerende actieve stof helpt om de microcirculatie van het bloed te stimuleren. Dit "tensor" effect is ideaal voor cellulitis en sinaasappelhuid.

Het is een krachtige antioxidant die de teint egaliseert en de glans van de huid verbetert. Het werkt ook tegen roodheid en andere irritaties dankzij de kalmerende eigenschappen.
