If Tranexamic Acid focuses on its effects, then 4MSK’s appeal is to enhance its self-healing power. Because when the skin metabolism process is not smooth, all the old dead skin cells on the epidermis cannot be shed, which not only makes the skin color darker, but also allows melanin to continue to accumulate in the skin.When the skin is exposed to ultraviolet rays again, melanocytes will be activated.Whitening products added with 4MSK can make the outermost layer of the skin's cuticle healthy and allow melanin to be discharged smoothly. When used in conjunction with various types of whitening products, the whitening effect of the original whitening products can be improved. It is more than 50 times that of penetrant or transdermal agent, showing good development prospects.
