AccessCARE Vita K1-Oxide

High-Performance Vitamin K Oxide for Dark Circles and Redness Reduction

INCI Name: Vitamin K1 Oxide

AccessCARE Vita K1-Oxide is a specialized, highly stable form of Vitamin K designed to target the underlying causes of dark circles and skin redness (erythema). By strengthening capillary walls and improving blood microcirculation, it helps reduce the appearance of pooled blood and hemoglobin deposits under the eyes and in areas of inflammation. This oil-soluble active is significantly more stable to light and air than standard Vitamin K1, making it a superior choice for advanced eye creams, anti-redness treatments, and post-procedure skincare.

Solubility Notes:

Oil-soluble. Incorporate into the oil phase of your formulation. Can be gently heated to ensure complete dissolution.

Performance & Formulation Insights for AccessCARE Vita K1-Oxide

How Vitamin K1 Oxide Works

AccessCARE Vita K1-Oxide addresses vascular-related skin concerns like dark circles and redness through its vital role in the blood coagulation process. Weak or damaged capillaries can leak red blood cells into the surrounding tissue. As these cells break down, the hemoglobin creates a purplish, bluish, or reddish discoloration, which is highly visible under the thin skin of the eye area.

Vitamin K1 Oxide works by activating the enzymes responsible for strengthening these capillary walls and supporting the body’s natural coagulation cascade. This action helps to prevent further leakage and allows the body to more effectively clear away the pooled blood, leading to a visible reduction in dark circles, bruises, and generalized redness. The “Oxide” form is a significant technological improvement over standard Vitamin K1 (Phytonadione), offering superior stability against oxidation from light and air, resulting in a more potent and reliable ingredient in cosmetic formulations.

Formulation Guidelines

AccessCARE Vita K1-Oxide is an oil-soluble active that should be incorporated into the oil phase of your emulsions or used in anhydrous (water-free) systems. Gentle heating (to 40–50°C) can assist in its dissolution. It is stable within a typical cosmetic pH range of 4.5 to 7.0.

For maximum efficacy, combine it with other actives that address different causes of skin discoloration. It pairs well with antioxidants like Vitamin C and Ferulic Acid, brightening agents like Niacinamide, and soothing ingredients such as Bisabolol and Allantoin to create comprehensive treatments for eye care and sensitive skin.

Key Formulation Benefits
