What Causes Discoloration Around The Mouth & How Can It Be Treated?

Discoloration anywhere in the body is due to the increased melanin production in the skin. It leads to darkened areas that tend to develop in small patches on the skin.

Skin discoloration is not of serious concern but can be because of underlying medical conditions, lifestyle habits, and medications.

These patches of discoloration do not require any treatment, but people find these patches bothersome.

What Causes Discolored Patches Around The Mouth?

There are several factors that can affect melanin production. Sun exposure, medications, underlying medical conditions, and hormone fluctuations are a few that can affect melanin production, particularly on the face. This leads to spots of hyperpigmentation around the mouth.

What Causes Discolored Patches Around The Mouth?


Melasma leads to dark brown and greyish-brown discolored patches on the forehead, cheeks, and upper lips. These are also nicknamed pregnancy patches. It is seen occurring more commonly in women.(1)

Melasma occurs due to hormone imbalance that occurs during pregnancy while taking hormone contraceptive pills, or undergoing hormone replacement therapy.

It occurs mostly on the face and is seen on the areas such as the upper lip, chin, cheeks, nose, and forehead. If the face is exposed to the sun these patches get more visible.

Side Effects Of Medications

Oral contraceptive pills are known to cause melasma. Other medications that can increase the risk of discoloration around the mouth are:

  • Hormone replacement therapy, especially estrogen hormone
  • Doxycycline can increase sun sensitivity thereby increasing the risk of hyperpigmentation
  • Chemotherapy drugs

Sun Exposure

The ultraviolet rays of the sun and tanning beds can increase the risk of developing discoloration on the face, chest, and arms.

This type of discoloration is also known as sunspots, liver spots, or age spots. The area around the mouth is at an increased risk as while applying sunscreen, you tend to skip this area.

There is evidence that indicates visible light can increase the risk of developing melasma.(2)

Skin Trauma

Any serious injury, acne breakout, burn, or infection around the mouth can also lead to discoloration. The spots can be brown or black after the skin has healed. It is also called post-inflammatory hyperpigmentation.

Discoloration around the mouth can also be due to lip balm or toothpaste. It is referred to as lip licker’s dermatitis.

Vitamin Deficiencies

Discoloration around the mouth can also be due to a deficiency of vitamin B12 and vitamin D.

A study found people suffering from melasma, were also deficient in vitamin D.(3)

Who Is More At The Risk Of Developing Discoloration Around The Mouth?

People with darker skin complexion are more prone to hyperpigmentation, as the melanin production is higher in them than in those with light skin.

Aging is another factor that increases the risk of hyperpigmentation. As you age, you may notice more spots on the skin around the face, chest, and other areas. The risk increases more if a person does not apply sunscreen properly in these areas.

The discolored spots increase around the summer months. It is due to increased sun exposure that can stimulate melanin and make hyperpigmentation more visible.
