Self clearing function is a function to dissolve melanin cap after its mission to protect cell nucleus is completed. It is human’s natural capability to become beautiful which mechanism has been already clarified by POLA.
In addition to decrease of the self clearing function due to aging or stress, POLA discovered that it also decreases by influence of “free fatty acid”. When self clearing function decreases, melanin cap is not properly dissolved and mass of melanin goes up to upper layer of epidermal skin. It leads to pigmentation, uneven skin tone and dull complexion.
