Tric acid and its derivatives are additives in whitening products, which can penetrate into the skin and have good whitening effect. Triglyceride is an effective inhibitor of tyrosinase, which can snatch copper ions with tyrosinase to make tyrosinase inactive and block the production of melanin for whitening and spot lightening purposes. It can be made by a variety of substances, in the form of Aspergillus ferment. Numerous studies have shown that Tricholoma is not an acute, chronic, reproductive toxic substance, and has very little effect on the human body because the amount of Tricholoma entering the bloodstream through the skin is very low. And it also has no phototoxicity and delayed contact reaction. Therefore, concentrations below 2% in cosmetics are safe and do not cause excessive adverse reactions. However, some manufacturers may add excessive amounts of tric acid to their products to meet consumer demand, which may lead to skin allergy and even dermatitis. To sum up, you should choose whitening products made by reliable manufacturers that contain tric acid ingredients, and it is safe to use in moderation. In addition, attention should be paid to moderate whitening, because excessive whitening may lead to too little melanin and cause skin cancer, white spots, etc.; it should not be in a strong light environment or too acidic environment, otherwise it may easily lead to the failure of tric acid.
