What's wrong with the blue spots on my body?

Condition analysis: After a child is born and even for a period of time thereafter, blue spots can be seen on the child's body, which is commonly known as "fetal blue marks."

Guidance: This blue spot is the result of the accumulation of pigment cells during the fetal period. It has no effect on the body. It gradually fades with age and does not require treatment. The blue one is called Mongolian spot. It is caused by the mother's exercise in the late pregnancy. The more severe the miscarriage, the larger the Mongolian spot will be when the child is born. It also indicates that the vestibular balance and tactile sense of the child will develop better in the late pregnancy. It starts from the lower back, that is, the coccyx, and extends to the back and then downward. It is the buttocks in appearance. Mongolian spots will fade. This kind of pigment spot is larger and darker in color on the buttocks and sacrum than in other parts. The shape of a single piece is also larger than two or more pieces, but the color is slightly lighter.

What is a blue birthmark?

The baby's cyan birthmark appears around one eye socket, temporal region, forehead, zygomatic region and nose wing, with scattered or progressively increasing spots or small patches. Occasionally, it occurs on both sides of the face, often showing bilateral symmetry. Some melanocytes are also distributed in special parts such as the conjunctiva, cornea and retina, in clustered distribution with different densities. Generally, the central part is darker and the edge is lighter. It can be brown, black, cyan and other dark colors. Some babies have cyan birthmarks on the sclera of the eyes, and the color is blue. If your baby has a cyan birthmark on his face, you can consider giving him a birthmark removal surgery.

What to do if your baby has a blue birthmark

1. Dermabrasion or skin grafting: This is a traditional method of treating blue birthmarks. It uses a grinding wheel to grind away the skin in the affected area. Some people directly remove the skin in the affected area and then graft it. This traditional method of treating blue birthmarks will undoubtedly leave obvious scars, and it is also very painful and difficult to maintain. Because it is a skin graft, even if the operation is the most successful, the transplanted skin will be very unnatural and the effect will not be very obvious, but the price will be low.

2. Cryotherapy: Cryotherapy for blue birthmarks freezes the tissue layer by layer from the surface of the skin to the inside. Since the lesions are deep, the treatment method of freezing blue birthmarks is very likely to leave scars. The depth of the freezing treatment method for blue birthmarks is not enough, and it is difficult to achieve the ideal effect.

3. Laser therapy: Laser therapy is the most common method for treating blue birthmarks. Laser therapy uses the selective photothermal effect of light on objects of different colors. Lasers of different wavelengths are used to selectively act on melanocytes in the dermis. Without damaging other skin tissues, the pigmented lesions are destroyed by photothermal force, thereby removing the melanin.
