Are the Birthmarks Dangerous?

Birthmarks are divided into two categories: red and pigmented ones. Pigmented birthmarks are common skin discolorations that rarely cause health issues. However, it can be a major aesthetic concern and a source of serious self-esteem problems.

Red birthmarks, on the other hand, are called vascular birthmarks because of the involvement of blood vessel overgrowth. These colored spots may develop before or after birth.

Types and Causes of Pigmented Birthmarks

Pigmented birthmarks are usually harmless and can show up in any part of the body. They can appear as small or large, flat or raised, brown, pink, black or may even change color as time passes.

Some pigmented birthmarks or moles may go away as you get older, but you may also develop new spots over time.

Strawberry marks or strawberry nevus is a type of vascular birthmark known as hemangioma, which commonly occurs in infants and children. These marks are rarely harmful but may require medical treatment if they cause deformities of the skin or affect a child’s hearing, vision, and breathing.

Moles (nevi)

A mole is a type of birthmark, but not all moles are considered birthmarks. For instance, a form of skin cancer called melanoma can appear in moles or spots on the skin. Normal moles like the ones you are born with are often seen as small, round, tan or black spots, sometimes with hair growing out of them.

Large congenital moles may lead to the development of skin cancer. If you notice unusual changes in your moles, such as itching or bleeding, you should consult your medical provider immediately.

Mongolian birthmarks

Mongolian spots are characterized by bluish patches that look like bruises on the skin. They are often seen on children’s buttocks or lower back, especially in people with darker skin (Asian, African, American Indian, and Hispanic).

Café-au-lait spots

As the name implies, this flat pigmented birthmark resembles the color of coffee with milk. They are generally harmless but in some people, they can be a sign of a genetic disorder called neurofibromatosis type 1 (NF1).

Café-au-lait spots are permanent but do not cause any illness or malignancy. Up to 20% of the population can develop these macules. Microscopically, the lesions are indistinguishable from melasma and freckles, thus they can be effectively removed by different types of lasers.

Effective Brown Birthmarks Removal

While most birthmarks should not be a cause of concern, some require treatment if they are cosmetically bothersome or growing rapidly.

Laser therapy can get rid of different types of pigmented birthmarks. As of now, there is no effective way to prevent birthmarks. Applying high SPF sunscreen is helpful for preventing complications but it will not prevent the formation of birthmarks.

Laser treatment for pigmented birthmarks

Brown or black spots and even vascular birthmarks respond well with laser treatments. Some birthmarks can only be treated with surgical excision but this often leads to scarring.

It has a longer wavelength that penetrates deeper vessels. It is used for treating age spots, freckles, darkened scars, café-au-lait spots, and other brown birthmarks.

According to a 2012 study, about 70% of participants treated with 1,064 nm Q-switched Nd:YAG laser showed complete removal of nevi (moles) after just one session. The remaining patients were completely treated after three sessions.

It is vital to have a realistic expectation of the treatment outcome if you are planning to get a laser treatment for your birthmark. Some spots will significantly improve but may not be completely removed. The majority of birthmarks require at least three sessions or more to achieve significant improvement.
