Vitamin k2 hydroxystearic acid complex: UnileverRecent Research Landscape

Melanogenesis instability and poor ingredient penetration limit the efficacy of topical brightening agents. This specific chemical synergy stabilizes the active delivery to improve skin tone uniformity.

What technical problems is Unilever addressing in Vitamin k2 hydroxystearic acid complex?

Dermal structural degradation

(17)evidences

Structural instability and moisture loss in the stratum corneum lead to dermatological vulnerability. Restoring barrier integrity prevents transepidermal water loss and environmental damage.

Dermal barrier degradation

(10)evidences

Melanin overproduction leads to uneven skin tone and hyperpigmentation. Reducing these visual defects provides a clear cosmetic and dermatological advantage.

Oxidative cellular damage

(8)evidences

Insufficient metabolic activity during the circadian repair cycle leads to diminished radiance. Addressing this deficit restores the skin's natural luminosity and regenerative capacity.

Excessive cutaneous melanin production

(2)evidences

Inadequate or excessive melanin production leads to aesthetic and physiological skin disorders. Regulating melanocyte activity restores natural skin tone and protective barriers.
