Freckles appearing on the face of small children are generally caused by heredity. Freckles have no effect on human health, so special treatment is generally not necessary. For those freckles that are more serious and have a great impact on aesthetics, local corrosion, chemical peeling, laser and other methods can be used appropriately to deal with them. At the same time, it is necessary to pay attention to avoiding sunlight and using shading agent when going out. 1. Local corrosion and chemical peeling: Trichloroacetic acid solution or phenol can be appropriately used to spot-coat freckles, which can prompt freckles to peel off, so as to achieve the effect of lightening the color spots, but some of them can form scar or pigmentation disorders, which have been seldom used. Secondly, some drugs with whitening and lightening melanin can also be applied appropriately, such as hydroquinone cream, etc., but it is necessary to make clear that the children are not allergic to the drug, and use it under the guidance of physicians. 2. Laser treatment: at present, the commonly used treatments include Q-switched ruby laser with a wavelength of 694nm, alexandrite laser with a wavelength of 755nm, or IPL treatment, which has a better efficacy, and should pay attention to the avoidance of light after the operation. Therefore, freckles on the face of small children is also a relatively normal phenomenon, as long as the symptoms are not serious, generally do not need special treatment.
