GH K-AT Serum: triple-action treatment for persistent dark circles and puffiness

Dark circles and puffiness have different causes — vascular, pigmentary or due to fluid and fat retention — and few formulas address all of them at once. GH K-AT Sérum by Gema Herrerías was specifically designed for this triple need: vitamin K oxide for purple dark circles, tranexamic acid for pigmented ones, and a three-ingredient niosome-encapsulated complex to reduce puffiness. All delivered through an elegant tri-roll-on applicator with a cold effect that soothes the area from the very first contact and enhances active penetration.

Action and Benefits

• Brightens vascular dark circles (blue/purple) by improving microcirculation and reducing vascular congestion.
• Reduces pigmentary dark circles (brown) by inhibiting melanogenesis and inflammatory mediators.
• Reduces puffiness by acting on all three causes: inflammation, fat accumulation and fluid retention.
• The cold-effect tri-roll-on applicator soothes congestion and improves lymphatic drainage from the first application.
• Fast-absorbing serum texture that allows the regular eye contour cream to be applied afterwards.
• White peony fragrance with no allergens. For resistant skin. Not suitable for sensitive skin.

Key Active Ingredients

• 1% Pure Vitamin K Oxide (Phytonadione Epoxide): oxidised form of vitamin K1 with greater activity, stability and skin tolerance. Acts on blood coagulation processes, reducing congestion, accelerating bruise reabsorption and activating microcirculation. Vasoprotective properties.
• 0.5% Tranexamic Acid: acts on melanogenesis and inflammatory mediators responsible for dark pigmentation in the eye area. Reduces inflammation-induced hyperpigmentation and improves skin tone evenness.
• Niosome Complex (Diosmin + Forskolin + Palmitoyl Tetrapeptide-7): advanced delivery system acting on the three causes of puffiness: diosmin reduces inflammatory and vasodilatory mediators; forskolin exerts a lipolytic effect reducing fat accumulation; palmitoyl tetrapeptide-7 improves lymphatic drainage and reduces oedema.

How to Apply

• Shake before first use.
• Apply twice daily by gliding the roll-on over the dark circle and puffiness area, from the inner corner towards the temple.
• Gently massage until fully absorbed, before your regular eye contour product.
• Store in a cool, dry place protected from natural light. Minimum durability: 24 months.
• Not suitable for sensitive skin or those allergic to vitamin K oxide. If accidental contact with eyes occurs, rinse thoroughly with water.
