Generally, spots can be removed or lightened to make the skin whiter through photorejuvenation and fruit acid resurfacing. 1. Photorejuvenation: Its strong light with specific wavelength acts on the melanin target group, causing melanin particles to break up and decompose, thus achieving the effect of whitening and removing spots. 2. Fruit acid skin resurfacing: professional concentration of fruit acid can make the melanin particles in the superficial parts of the skin fall off, and promote the proliferation of collagen fibers, reduce skin aging, get rid of pigmentation, and make the skin whiter. In daily life, pay attention to strict sun protection, avoid oral photosensitive food and drugs, and strengthen moisturizing. In addition, it is recommended that patients go to regular hospitals and standardize the treatment under the operation of specialized doctors.
