Hello, the effect of acne products is not obvious. It is suggested to consider using laser to remove acne, and the effect is good. You can choose laser acne, that is, using a laser with a specific wavelength has a strong effect on inhibiting excessive sebum produced by acne and killing a variety of bacteria that cause acne, so that new acne can be returned in time. In addition, the laser can effectively stimulate the regeneration of collagen in the skin, so that the uneven traces left after acne can be restored to smoothness. With the laser grinding function, it integrates the two-way effects of acne removal and scar removal, and the treatment of acne is more perfect. The most effective and quickest way to remove spots is to choose laser to remove spots. The principle of laser spot removal is that different types of lasers produce different colors of light, and the laser of a certain wavelength is only absorbed by the pigment of the corresponding color. Therefore, the shaping mechanism uses a laser instrument to generate a high-intensity beam to make the pigment fade, so as to achieve the purpose of removing pigment spots. The treatment time of laser depigmentation is relatively short, only about ten minutes at most. After each treatment, the skin should be given a metabolic process. Therefore, the interval of laser pigmentation treatment is usually 3 months.
