Whitening injections are effective for skin whitening, but the specific effect is related to the number of times you play and daily maintenance. Whitening injections are a mixture of preparations that have a role in lightening spots, both for chloasma and other discoloration. Whitening injections also contain a certain amount of reducing agents, including vitamin C, glutathione, and other vitamins, which promote skin metabolism and metabolize pigmentation. It is true that whitening injections at regular intervals can keep the skin fair and tender, but long-term use can increase the load on the liver and kidneys. And because of its hemostatic effect, some patients may affect their menstruation after using it, and it may cause coagulation dysfunction if they are older. So it is not recommended to just inject whitening injections, patients who need it should go to regular hospitals to avoid adverse effects on the body. In addition to whitening injections, you can also use some hydrating and whitening masks or topical essences containing L-VC and niacinamide to help improve, and you can also eat more vitamin-rich foods, pay attention to skin cleanliness and sun protection, and don’t stay up late too often.
