In an in vitro experiment, a cosmetic whey derived from NKG Kefir was prepared at various concentrations to evaluate its ability to inhibit tyrosinase activity.

Methodology

• -The assay used mushroom-derived tyrosinase and tyrosine as the substrate, a standard model to measure enzymatic activity related to melanin production.

• -The tyrosinase activity inhibition rate (%) was measured to determine how effectively the kefir whey suppresses the enzyme.

Key Findings

• -NKG Kefir whey exhibited significant suppression of strong tyrosinase activity in a concentration-dependent manner.

• -This suggests that components within the whey can inhibit the enzyme responsible for melanin synthesis, which is linked to pigmentation processes.

Implications

• -The inhibitory effect on tyrosinase points to potential uses of NKG Kefir whey as a natural skin-brightening agent or ingredient in cosmetic formulations aimed at reducing hyperpigmentation.

• -It also highlights the broader cosmeceutical potential of fermented dairy products like kefir.
