The Use Of Kojic Acid To Be Mixed In A Mask?
I want to use kojic acid powder to be mixed in a mask or body lotion … then what is the maximum amount / weight that can be used? And are there other ingredients that need to be combined so that the kojic acid content remains stable?
Kojic acid is an ingredient obtained from a combination of mushrooms and can also be obtained as a by-product of soy fermentation and sake drinks. In facial care products, kojic acid is added to obtain the efficacy of brightening skin tone, fading hyperpigmentation and acne scars. Kojic acid can affect the production of melanin (a skin pigment). Besides kojic acid also has antibacterial and antifungal effects.
Kojic acid can be found in various beauty products in the form of soaps, lotions, creams, and serums. The recommended concentration of kojic acid is 1-4%. The use of kojic acid with high concentrations can trigger tumor growth in medical studies in experimental animals. However, the results of this study are doubtful, because only a very small percentage of kojic acid can be absorbed in the systemic blood circulation when used topically on the skin.
Kojic acid in the form of raw powder, is not recommended directly used on the skin. You must know the percentage of the kojic acid powder concentrate you are using, and what volume of solvent you will use to calculate the final percentage of kojic acid in your product. It will be easier to use products that already display the appropriate percentage of kojic acid to use.
The initial use of kojic acid can cause skin purging like when using treatment ingredients that contain retinol. Generally, small pimples will occur in areas where acne usually grows, but they will disappear faster than normal zits. Contact dermatitis can also occur in people with sensitive skin when using kojic acid. The use of kojic acid on the skin will cause the skin to burn more easily when exposed to sunlight, therefore the use of sunscreen must be done routinely and reapplication if necessary.
Thus the explanation from me, hopefully useful.
