How many courses of treatment are recommended for whitening injections?

The effects of whitening injections typically become noticeable only after completing several consecutive treatment cycles. Generally, the best whitening results are achieved after two to three cycles. The frequency and duration of each treatment cycle may vary depending on individual conditions and the doctor's recommendations. For standard whitening injections, a complete treatment cycle lasts three months, with one treatment every 7 days, totaling 21 treatments. For enhanced whitening injections, the treatment cycle is every 10 days, totaling 30 treatments. Whitening injections can inhibit melanin synthesis and accelerate skin metabolism, gradually lightening the skin tone. However, it is important to note that the effects are not permanent, and individual responses may vary. Additionally, whitening injections have not been approved by national regulatory authorities and carry certain risks; therefore, they should be administered only under the guidance of a qualified physician.
