What Causes Dark Spots on the Skin?

At Serenity Aesthetics in Grapevine, Texas, medical aesthetician Stephanie St. Aubin and physician assistant Hannah Dodge, PA-C, help clients understand and treat many different skin concerns, including dark spots. While these patches of discoloration are common and often harmless, knowing what causes them can help you choose how to approach prevention and treatment.

Sun Exposure And UV Damage

The most frequent cause of dark spots is sun exposure. When skin is exposed to ultraviolet (UV) light, it produces more melanin to protect itself. Over time, repeated exposure can lead to areas of hyperpigmentation, often referred to as sun spots, liver spots, or age spots. Even casual exposure, like driving or walking outside without sunscreen, can contribute.

Hormonal Changes

Fluctuations in hormones can trigger melasma, a condition that causes symmetrical patches of discoloration, typically on the face. Pregnancy, birth control use, and hormone therapy make dark spots more likely. While melasma can fade over time, it often requires aesthetic treatments and ongoing sun protection to prevent recurrence.

Post-Inflammatory Hyperpigmentation

After an injury to the skin, such as acne, eczema, cuts, or burns, the healing process may leave behind darkened areas. This is called post-inflammatory hyperpigmentation (PIH). PIH can affect any skin type, but it tends to be more noticeable and persistent in deeper skin tones. Visiting our Grapevine, Texas, office for help managing injuries and flare-ups can help prevent dark spots from developing.

Aging And Genetics

As skin ages, its natural repair processes slow down, and sun-related pigmentation becomes more visible. Genetics also play a role, some people are simply more prone to developing dark spots than others, regardless of lifestyle.

Medications And Medical Conditions

Certain medications, such as some antibiotics, chemotherapy drugs, and anti-seizure medicines, can increase sensitivity to the sun or trigger pigmentation changes. Liver disease or endocrine disorders can also affect skin tone. Serenity Aesthetics can help manage these changes, as well.

Removing And Preventing Dark Spots

Stephanie St. Aubin and Hannah Dodge at Serenity Aesthetics use treatments such as chemical peels, laser therapy, and medical-grade skincare products to reduce the appearance of dark spots. Preventive care is equally important, daily use of a broad-spectrum sunscreen, protective clothing, and consistent skincare habits can make a big difference in keeping new spots from forming.

Dark spots don’t have to be permanent, and in many cases, they can be significantly improved with the right care. If you’re ready to learn which treatment is best for your skin, schedule a visit to our Grapevine, Texas, office by calling (817) 280-9616.
