Causes

Man with dark or black skin and acne.
Acne can cause dark spots and scars.

Dark spots may appear on black skin when the skin produces too much melanin. Melanin is the substance that gives skin color.

Factors that can trigger excess melanin production include sun exposure and hormonal changes, such as those that occur during pregnancy.

Dark spots can also occur as a result of inflammation or trauma to the skin, such as:

Even everyday skin care practices can contribute to the development of dark spots. The use of rough scrub, waxing and shaving can cause minor traumas on the skin that can cause changes in the skin.

How to get rid of dark spots

The treatment a person requires will depend on their skin type and the severity of the discoloration. Dark spots are not usually harmful, so it may not be necessary to seek treatment unless a person finds them annoying.

The treatments include:

The "wait and see" approach

In some cases, no treatment can be the best option, since the spots can disappear with time.

For example, this may be the case of some types of hyperpigmentation that occur during pregnancy or those that appear after the acne goes away.

Meanwhile, the use of sunscreen can help prevent the spots from darkening.

Elimination of the cause

If the discoloration is the result of a skin care product or certain medications, the suspension of the use of these products can prevent the formation of new dark spots.

According to the American Academy of Dermatology (AAD), once a person eliminates the cause of the spots, those that already exist will usually disappear within 6 to 12 months. However, daily use of sunscreen is important to help the area fade and prevent the sun from darkening it.

However, darker spots may take years to disappear. In these situations, medical treatments or skin lightening products can help.

Treatment of underlying medical conditions

Proper management of existing skin conditions, such as acne or psoriasis, is likely to help stop the appearance of new spots.

Any dark spots that are already on the skin due to these conditions may disappear with time.

Sunscreen

Adequate sun protection is recommended for everyone, regardless of skin type or color, however, research suggests that the use of sunscreen is especially low among non-Hispanic black people.

The ultraviolet (UV) rays of the sun are responsible for most dark spots on the skin. UV rays activate excess melanin production, causing new areas of hyperpigmentation and obscuring existing areas.

The AAD recommends that everyone use sunscreen that:

  • has a sun protection factor (SPF) of at least 30
  • protects against UVA and UVB rays (manufacturers can label it as broad spectrum)
  • It is water resistant

People should apply it on all areas of exposed skin, not just on the face, and use it throughout the year.

Sunscreen is available in pharmacies and online.

Some people claim that natural remedies can effectively reduce dark spots on black skin. The most popular remedies include:

However, there is no scientific evidence that these natural treatments alleviate areas of hyperpigmentation. Some of them can even cause other skin problems. For example, lemon juice can dry and irritate the skin.

In general, however, it is unlikely that these natural products will cause harm if people use them in moderation.

Products to lighten the skin.

Several over-the-counter products are available to treat an irregular skin tone. To get the best results, a person should choose a skin lightener that contains one of the following:

Vitamin C

Vitamin C is a powerful antioxidant. When it comes to skin care, research suggests that it can protect against sun damage, increase collagen levels and reduce melanin formation to stop hyperpigmentation.

However, it is not clear how effective it can be due to the limited ability of current preparations to penetrate the skin.

Vitamin C serums are available in pharmacies and online.

Hydroquinone

Hydroquinone is a very popular treatment for dark spots. Similar to vitamin C, it works by inhibiting the production of melanin.

Over-the-counter (OTC) products generally contain 2% hydroquinone, while prescription creams contain 4%.

Creams that contain hydroquinone are available at some pharmacies, pharmacies and online.

Kojic acid

Kojic acid is another common skin lightener.

However, it may be less effective than other remedies for dark spots. A study on a type of hyperpigmentation called melasma found that a 4% hydroquinone cream was a better and faster treatment for hyperpigmentation than a 0.75% cream of kojic acid.

People can buy kojic acid solutions online or in some pharmacies.

Gel differin

Adapalene 0.1% gel (Differin) is an over-the-counter treatment that is anti-inflammatory and helps stop the formation of acne comedones.

Dermatologists can recommend it to match the complexion of a person's skin and lighten dark spots, in addition to preventing acne outbreaks.

Medical treatments

If home remedies do not help get rid of dark spots, some people may want to consider medical treatments.

These can cause adverse reactions, so it is best to discuss the advantages and disadvantages of each option with a dermatologist before receiving treatment.

Medical treatments include:

Laser therapy

Laser therapy uses a beam of light to eliminate areas of hyperpigmentation.

Research indicates that laser therapy is effective and gives lasting results. However, it is expensive and requires multiple sessions. It can lighten the skin surrounding the dark spots if the doctor accidentally attacks those areas. It could even produce a lighter point instead of the dark point.

Chemical peels

Chemical peels exfoliate the skin but deepen more than other processes, such as microdermabrasion. Although they can be effective, strong chemical peels can burn the skin or even produce additional pigment changes.

This treatment can be expensive, and a person may require several sessions to achieve remarkable results.

Treatments to avoid

People should avoid the use of very aggressive treatments on the skin, as they can cause damage to the skin and serious damage to internal organs.

For example, some online sources recommend the use of liquid bleach in dark spots. People should never apply this product to the skin, as it can cause painful burns.

In addition, it is important to be careful when buying skin brighteners and avoid those that contain mercury, which can appear in the lists of ingredients such as:

  • mercury
  • mercury
  • calomel
  • cinnabar
  • hydrargyri oxidum rubrum
  • quicksilver

The World Health Organization (WHO) warns that soaps and skin-lightening creams containing mercury could cause:

Finally, mercury in cosmetic products also ends up in water. Here, it makes its way into the food chain, which means that people may end up eating fish that contains toxic levels of mercury.

Prevention

It may not be possible to prevent all cases of dark spots on black skin, especially those that occur due to aging and hormonal changes.

However, it is possible to reduce the risk of their development:

  • Use sunscreen with an SPF of at least 30 every day.
  • Reapply sunscreen every 2 hours and more frequently after swimming or sweating.
  • Avoid direct sunlight between 10:00 a.m. and 4:00 p.m.
  • Hydrate the skin daily.
  • Avoid the use of aggressive exfoliating products.
  • treat acne, psoriasis and other conditions promptly
  • See a doctor if the black spots are the result of the contraceptive pill or other medications.

When to see a dermatologist

People who find their dark spots annoying may want to see a dermatologist, especially if home remedies do not achieve satisfactory results.

Those who have skin conditions that trigger the development of dark spots should also consider making an appointment with a dermatologist to explore treatment options.

Summary

Dark spots are a common problem for people with black skin. They are harmless, but some people may wish to treat them for cosmetic reasons.

Home remedies include treating the underlying cause and using skin lighteners.

If these do not work, people can discuss the possibility of laser therapy or other treatments with a dermatologist.
