Melanocyte-Stimulating Hormone | Stimulates melanocytes to produce melanin; elevated MSH levels suggest increased melanin synthesis |
Melanin Content in Skin Cells (via Spectrophotometry) | Measures melanin levels directly in skin samples, providing a clear indicator of pigmentation. |
Glutathione Peroxidase (GPx) | Converts hydrogen peroxide into water, another key marker of antioxidant activity. |
Gene Expression of MITF, TYR, TYRP1, and TYRP2 | Genes involved in melanin synthesis, where upregulated expression indicates increased melanin production. |
Tyrosinase Activity | Tyrosinase is the key enzyme in melanin synthesis. Increased activity reflects higher melanin production. |
