Dark spots on the face can result from hyperpigmentation, when the skin produces too much melanin. Various medical and cosmetic treatments and home remedies may help remove or reduce them. Many dark spots are harmless. However, if a person wants to reduce their appearance, they can usually do by using topical treatments. This article will look at dark spots that result from hyperpigmentation. It will discuss their causes, how to get rid of them, and some treatment options. It will also look at approaches and ingredients that people should avoid. What causes dark spots on the face? Share on Pinterest Getty Images Dark spots on the face can occur if the skin overproduces melanin, which is the pigment that gives skin its color. This is known as hyperpigmentation. Hyperpigmentation can develop as a result of: aging

hormonal changes, such as during pregnancy or menopause

sun exposure Skin damage can also cause post-inflammatory hyperpigmentation (PIH). People may develop PIH due to: acne

bites, cuts, and burns

excessive or incorrect hair removal techniques

ingrown hairs

harsh skin care products

scarring from psoriasis or other skin conditions Hyperpigmentation is not the only cause of dark spots on the face. For this reason, it is important for a person to speak with a doctor if they notice any changes to existing moles or dark spots — particularly changes in texture, color, and size. Topical treatments for dark spots There are many over-the-counter (OTC) products that can help fade dark spots. They will typically contain active ingredients such as: kojic acid

retinoids

chemical exfoliants

vitamin C

azelaic acid These products will have instructions on how to use them on the label. However, it is best to speak with a dermatologist before trying them, as some have risks. The following sections will look at some of the pros and cons of these products in more detail. Hydroquinone Hydroquinone is a popular ingredient in products for hyperpigmentation. It works by reducing the production of melanin. Some countries have banned hydroquinone due to safety concerns. For example, research from 2007 suggests that hydroquinone may cause cancer in rats. However, scientists have not proven that this also occurs in humans. Hydroquinone can cause skin irritation, especially when people use higher concentrations of it. It may also lighten the skin surrounding the dark spots if a person does not apply it carefully. Kojic acid Kojic acid is another popular treatment for hyperpigmentation. However, it may not be as effective as other treatments. One 2013 study compares 0.75% concentration of kojic acid with 4% hydroquinone for treating melasma in 60 people. The researchers suggest that hydroquinone works more effectively. Kojic acid can also irritate sensitive skin, so it may not be suitable for everyone. Retinoids Retinoids are derivatives of vitamin A. They increase the turnover of new skin cells, which can fade dark spots over time. Doctors may prescribe a professional-strength retinoid, such as tretinoin, for severe hyperpigmentation. These products can take 3–6 months to work. The stronger the retinoid, the more likely it is to cause irritation. Products containing retinoids are not suitable for use during pregnancy, as vitamin A can sometimes cause birth anomalies. Retinoids also increase the skin’s sensitivity to UV light, so it is important to use a safe SPF on the face every day while using retinoids. Chemical exfoliants Chemical exfoliants are acids that dissolve the top layer of skin cells. They include alpha hydroxy acids, such as lactic acid, and beta hydroxy acids (BHAs), such as salicylic acid. Chemical exfoliants also work by increasing the turnover of new skin cells. They can also be suitable for dry or sensitive skin. However, as with retinoids, these acids increase the skin’s sensitivity to the sun. Cosmetic procedures for dark spots If topical products do not adequately reduce hyperpigmentation, some people may wish to consider cosmetic procedures. Some potential options include: Laser therapy: This involves a dermatologist using a beam of light to target areas of discoloration. There is a risk that laser treatment will make discoloration worse, so patch testing beforehand is essential.

Chemical peels: Professional chemical peels are stronger versions of OTC acid exfoliants. Stronger peels work on deeper layers of the skin, but they also have longer recovery times. Professional chemical peels are stronger versions of OTC acid exfoliants. Stronger peels work on deeper layers of the skin, but they also have longer recovery times. Microdermabrasion: This exfoliating treatment uses minuscule particles to remove dead skin cells. There is no recovery period, though it can make the skin temporarily irritated or swollen. People who are prone to PIH or scarring or who have used isotretinoin in the past 6 months may not be able to undergo microdermabrasion, chemical peels, or laser therapy. Choosing a treatment How a person uses products for hyperpigmentation will depend on a number of factors. The following sections will look at these in more detail. Skin tone People with dark skin tones need to exercise caution when using treatments for hyperpigmentation. This is because using the wrong product or a highly concentrated product can lighten other areas of the skin. There is also a risk that products will cause more hyperpigmentation. The American Academy of Dermatology (AAD) recommends the following treatments for dark spots in skin of color: 2% hydroquinone

azelaic acid

glycolic acid

kojic acid

retinoids, such as retinol, tretinoin, adapalene gel, or tazarotene

vitamin C A dermatologist with experience in treating hyperpigmentation in dark skin can advise on the best approach. Learn more about getting rid of dark spots on black skin here. Underlying conditions People may need to address skin conditions that are causing hyperpigmentation in order to prevent dark spots from appearing. For example, if a person has PIH as a result of acne, treatment can focus on fading discoloration as well as preventing acne and acne scarring. Treatment may involve: BHAs, which can both fade discoloration over time and help treat acne

retinoids, which people can use topically or orally

diet or lifestyle changes Learn more about preventing pimples here. Sun damage If a person has dark spots as a result of sun damage, they should add an effective sunscreen to their skin care routine. Sunscreen stops the darkening of existing hyperpigmentation and prevents more UV damage from occurring. Everyone should wear sunscreen every day, regardless of their skin tone. The AAD recommends choosing one that: has an SPF of at least 30

protects against UVA and UVB rays

is water resistant Vitamin C may be an especially helpful treatment for sun damage. One 2017 review notes that topical vitamin C is effective for preventing melanin formation and protecting against premature skin aging as a result of UV exposure. Medications Some topical and oral medications may cause or worsen hyperpigmentation. People can check the label on any medication to see if this side effect is a possibility. If it is, a doctor can advise on the best course of action. The AAD states that once a person removes the cause of their hyperpigmentation, existing spots should fade in 6–12 months. However, very dark spots may take longer than this to fade. Hormonal changes Dark spots that arise due to hormonal changes are not always avoidable. However, some mild discoloration may fade over time once a person removes the cause. For example, if a person is pregnant, the marks may start to fade when the pregnancy is over. Melasma can be more stubborn to treat. Melasma is a deeper form of hyperpigmentation that can occur due to hormonal changes. Even when melasma fades, it can come back if a person has exposure to the sun. If a person is pregnant or nursing, they should check with a doctor that any hyperpigmentation treatments or procedures are safe to use. Things to avoid Some skin-lightening practices can be dangerous. For example, the AAD warns against using liquid bleach on the skin. This can cause serious burns. Some skin-lightening products can also contain unlisted ingredients, such as steroids, which people should not use without medical supervision. Others can even contain mercury, which is highly toxic. Mercury may appear on ingredient lists as: mercuric
