Therefore, interpretations are limited exclusively to experimental neuroendocrine research systems and should not extend beyond scientific investigation contexts

It is, however, one of the most consistently evidence-backed brightening and protective ingredients in skincare and with realistic expectations and daily consistency, the results are genuinely meaningful

It is also used to calculate Low Density Lipoprotein Cholesterol (LDL-C) value and ratio of Total Cholesterol and High Density Lipoprotein Cholesterol (HDL-C) as TC/HDL-C
