The knee whitening treatment generally begins with a thorough cleansing of the knee area to remove any dirt, oils, and impurities that may interfere with the procedure. A professional-grade exfoliating scrub or chemical exfoliant is then applied to remove dead skin cells and stimulate cellular turnover. This step is crucial for enhancing the penetration of subsequent treatments. In some cases, a mild dermabrasion technique may be utilized to further smooth the skin surface. After exfoliation, the knees are rinsed and dried.

Following the exfoliation process, a skin-lightening agent, such as a cream containing ingredients like hydroquinone, kojic acid, or Vitamin C, is applied to the knee area. These agents work by inhibiting melanin production, helping to reduce hyperpigmentation. The treated area may then be covered with a occlusive dressing or left to absorb naturally, depending on the product's specifications and professional guidance. Some treatments may include a follow-up with a light therapy session to enhance the whitening effect and expedite results. The procedure typically concludes with the application of a moisturizing sunscreen to protect the treated skin from UV exposure, which can counteract the whitening process and potentially cause further darkening. Regular follow-up sessions and at-home maintenance regimens are usually recommended to achieve and sustain optimal results.
