Some birthmarks that are lighter in color and do not affect normal life can be gradually diluted with some products, and the cost will be very small. Many people will use lasers, and the cost may be higher. In short, the price needs to be determined according to your own situation.
Formation of birthmark:
The birthmarks on the body are different in size and position. There are four main reasons for the formation of birthmarks.
First of all, external environmental factors, whether rural or urban, have been polluted. When people are stimulated in a polluted environment, they will react, and birthmarks are one of the manifestations.
Second, the living environment, due to bad habits in life, or irregular diet and sleep, may cause birthmarks.
The third is heredity, which is also considered to be an important factor causing birthmarks, but there is no exact scientific basis.
Fourth, malnutrition, due to the lack of certain nutrients or trace elements, leads to a large amount of pigment secretion, forming a birthmark.
