Dark spots are often harmless, but if you want to remove them, you can try at-home topical treatments. Some people choose to undergo medically supervised laser treatment or chemical peels, but these are not appropriate for everyone.

Tips to Prevent Dark Spots

The sun and tanning beds are the most significant cause of dark spots. They are most likely to appear on parts of the body that receive the most sun: the face, back of the hands, shoulders, arms, and back.

Hyperpigmentation often appears during middle age because that’s when the skin starts to show the consequences of sun exposure. This is especially true if you didn’t use sunscreen and other sun-protective measures consistently earlier in life.

People with light hair or skin and who have had many sunburns, or severe ones, are at particular risk for dark spots.

However, UV exposure alone may not cause hyperpigmentation. Rather sun exposure combined with other factors cause the skin to develop dark spots. For instance, the risk of pregnancy-related hyperpigmentation may be increased with sun exposure.

How Melanoma vs. Sunspots Look on Skin

Certain medications can cause dark spots because they make the skin more sensitive to sun exposure (also known asphotosensitivity). These include the following:

A number of medical conditions can cause discoloration of the skin. Specifically, dark spots may also be a symptom of these conditions:

Some research has indicated that hydroquinone may cause cancer at higher concentrations.For this reason, the Food and Drug Administration has limited the concentration of hydroquinone to 3% to 4% in prescription products and 2% in over-the-counter (OTC) products.

Side effects, including redness, swelling, and skin irritation can occur with any topical medication. Skin lightening products contain abrasive ingredients that also make the skin extremely sensitive to UV exposure. So it’s essential to wear sunscreen with SPF consistently throughout treatment.

Arbutin: An Anti-Inflammatory Skin Care Ingredient

Healthcare providers and estheticians can use medical procedures to treat dark spots on any part of the body. They are often used along with topical treatments. However, some may not be appropriate for people with sensitive skin. Options include:

Summary

Dark spots commonly occur as people age. They are often the result of past sun exposure. But they can also be due to some skin conditions, medications, and certain medical conditions.

Dark spots are usually harmless. Even so, some people choose to have them removed for cosmetic reasons. Treatment options include skin-lightening creams and cosmetic procedures.
