Further, the present compound has a strong reducing action and a radical suppressing action, and is a compound excellent in safety since it is derived from a living body.
- the mechanism of melanin formation which is the basis of stains and freckles, is as follows. First, free radicals are generated in the skin by ultraviolet rays, and the stimulation activates melanocytes. As a result, the activity of tyrosinase in melanocytes becomes active, and After several stages such as oxidation and polymerization, it becomes melanin. The function of most whitening agents is to prevent the production of melanin by inhibiting the enzyme cinnamate.
- this compound has an effect of eliminating the melanin pigment aggregation deposits (stains, freckles, lentils) already formed in the compound. In other words, this effect is thought to be due to another mechanism rather than the tyrosinase or elastase inhibitory effect.
- Methods for removing moles include surgery, potassium hydroxide-starch, and liquid nitrogen, all of which damage the skin.
- a method for selectively destroying melanin-containing cells by laser light has been known.
- laser treatment itself causes inflammation during irradiation, and there is a possibility of recurrence.

- it was effective for spots such as two-acne scars, and there was a marked difference from before use.
- the present compound has an action of eliminating melanin pigment.
- the concentration of the compound used is usually 0.001 to 5 (w / w)% for ointments and creams, preferably 0.01 to 1.0 (w / w)%, and 0.001 to 5 (w / w)% for aqueous solutions or lotions.
- w / v)% preferably 0.01 to 1.0 (w / v) ⁇ 3 ⁇ 4.
