How long does it take for dark spots to fade after whitening treatment?

   It may take one to three months for skin darkening after pigmentation removal to recover. The exact time is not fixed and depends on the severity of the skin darkening and the aftercare. Detailed analysis is as follows:

   Skin darkening after pigmentation removal is a relatively common phenomenon, which may be caused by damage to subcutaneous cells, resulting in mild hyperpigmentation. With regular skincare treatments and application of skincare products, recovery generally begins after about one month. If the darkening is severe and post-treatment care is inadequate, the recovery period may be prolonged, potentially requiring up to three months. During the recovery period, it's also advisable to visit a dermatologist at a hospital for evaluation and, under a doctor's guidance, consider treatments such as photorejuvenation.

   Avoiding UV exposure is also necessary during the recovery period to reduce pigmentation. To prevent the occurrence of rebound hyperpigmentation, it is recommended to fully understand the treatment principles, risks, and necessary precautions before undergoing pigmentation removal, and to perform the treatment under the guidance of a qualified physician. After treatment, strictly follow the doctor's post-care instructions, and diligently perform daily skincare routines including sun protection and hydration.
