Ideal for all skin types, it dissolves best in warm water and shows visible lightening effects within 1-2 months of daily use. Formulate your own custom skincare blends by combining it with antioxidants like Vitamin E and Vitamin C for enhanced results and stability. ## Description Natural Mild Inhibitor of the pigment formation, induces skin lightening and helps establishing an even skin tone on all skin types. It can also minimizes liver spots. Kojic acid was originally found during the fermentation process of malting rice for use in the manufacture of sake. Question 1: which concentration of Kojic Acid should I use ? For skin lightening, the recommended safe and effective concentration range is 1-4%. It may go higher in some products, especially the wash-off products, but it could cause irritation and other side effects. Normally, kojic acid is used everyday and takes 1-2 month to see the effect. Question 2: How to mix kojic acid to my skincare product? To mix kojic acid, it need to be dissolved in water first. Be sure to use warm (25-40°C/77-104°F) water since it may lose some of its activity if put into hot water (>40°C/104°F). Kojic acid has tendency to oxidize over time, use vitamin E tocopherol or BHT (Butylated hydroxytoluene) in the cream to reduce oxidation. It's often be combined with other skin lighteners, such as vitamin C to get better result. Review: Best bang for your buck. - Have had zero issues with this product. It is a fine crystalized substance in which I used to make lightening lotion for personal use. Effects I cant remark on as I havent been using the product mixture for an extended period, but I expect as mixing/activation instructions were provided I should see results.
