Vitamin K 1 L

Strengthening capillaries and reducing dark circles in professional skincare lines

Vitamin K supplied in a 1 liter container is intended for manufacturing labs and studio-scale production that need a reliable stock of raw material for recurring batches. This ingredient belongs to the Vitamins section, which brings together active substances used across skincare, anti-aging and restorative cosmetic formulas. Worldwide, the strongest demand for vitamin K comes from the cosmetic industry, where it is used in eye contour creams, anti-redness and anti-couperose treatments, post-procedure recovery products after peeling or laser sessions, and formulas targeting fragile capillaries and bruise-prone skin. Professional and pharmacy-oriented cosmetic brands rely on this component to visibly reduce vascular networks and support capillary strength over time.

During production, vitamin K is added at the cooling stage of an emulsion, once the mixture drops below roughly 40 degrees Celsius, since higher temperatures can reduce its activity. Typical usage levels range from 0.5 to 2 percent of the total formula weight, depending on the desired intensity and the base being used. The ingredient pairs well with other vascular-supporting actives: combined with Vitamin P, it reinforces capillary strength, while Vitamin B10 helps even out skin tone and calm irritation. This type of multi-active approach is visible in a finished product such as the Antioxidant vitamin serum for skin hydration, which combines several vitamins in one formula.

Beyond cosmetics, vitamin K also finds use in pharmaceutical production of vascular support formulas and in some dietary supplement niches, though the largest share of wholesale purchases of this raw material still comes from cosmetic laboratories and small production studios developing their own creams, serums and gels. A 1 liter container fits well with steady batch planning, reducing the need for frequent reordering, which matters for facilities running a consistent production schedule.

Store vitamin K in a tightly sealed container, in a cool place away from direct light and air exposure, since contact with oxygen and ultraviolet light lowers its activity. Once opened, it is best to use the raw material within the period recommended by the supplier rather than leaving it exposed for long periods. Before adding it to a formula, warm the ingredient slightly to room temperature and mix thoroughly with the base to ensure even distribution throughout the batch.

Eye contour cream for capillary support

Distilled water 700 ml

Plant-based emulsifier 60 g

Grape seed oil 100 g

Vitamin P 5 g

Vitamin B10 5 g

Vitamin K 15 ml

Broad spectrum preservative 8 g

Heat the water to about 70 degrees and dissolve the emulsifier in it, while warming the grape seed oil separately to the same temperature, then combine both phases and mix until a smooth emulsion forms. Cool the mixture to around 38-40 degrees before adding vitamin K, vitamin P, vitamin B10 and the preservative, blending gently until fully uniform. Transfer the finished cream into sterile jars and let it rest for a day at room temperature before checking its stability.
