Top 6 skincare ingredients to treat hyperpigmentation

From small dark spots to large brown patches, hyperpigmentation can appear in many forms. But, no matter what it looks like, most of us don’t like it and want to do something about it. 

This discolouration of the skin is natural and completely harmless. And it’s common, too. Here at Face Dr, our experts have seen hundreds of clients with hyperpigmentation and—most importantly—we’ve helped them to lighten the look of these dark spots and patches.

Luckily, there are ingredients out there which help to lighten the look of dark spots and prevent new ones from forming.

What causes hyperpigmentation? 


Hyperpigmentation is caused by an excess of melanin in the skin—this the natural pigment which gives our skin, hair and eyes their colour. When melanin clusters together it forms dark spots and discoloured patches on the surface. 

There are three different types of hyperpigmentation and, for the most part, most ingredients can help with all of them. These three main types of hyperpigmentation are: 

  • Sunspots
  • Melasma
  • Post-inflammatory hyperpigmentation

The most common type of hyperpigmentation are sunspots which are caused by sun exposure when the body produces excess melanin to protect us against harmful UV rays. 

Melasma is caused by hormones and is usually due to pregnancy, the birth control pill or hormone treatments. 

The third type of hyperpigmentation is post-inflammatory hyperpigmentation which is caused by inflammation in the skin due to injury or skin conditions like acne and eczema. 

No matter which type of hyperpigmentation you have, choosing skincare products is tricky. With endless ingredients lists and scientific names, it can be hard to know exactly what you’re putting on your skin and which ingredients can help—and which could make things worse. 

To help, here’s our deep dive into ingredients you should look out for when choosing skincare products for hyperpigmentation. 

Which ingredients treat hyperpigmentation? 


Mandelic acid

Who’s it for? Mandelic acid is ideal for those with sensitive skin as it’s gentler than other products. It’s also had great results on darker skin types and for those with melasma.  

Product to try: Bea Skincare Brightening Serum

Despite the scary name, mandelic acid is actually made from almonds. It’s a type of alpha hydroxy acid, or AHA, a group of acids which are used in a variety of skincare products from acne treatments and anti-ageing products.

Mandelic acid works as an exfoliant and removes dead skin cells by breaking down the connections between them with its acidic properties. It also promotes skin cell turnover, so a brighter complexion and more even skin tone can come through.


Glycolic acid 


Who’s it for? Glycolic acid tends to work better on fairer skin tones as those with darker skin could experience scarring or post-inflammatory hyperpigmentation if the skin reacts

Glycolic acid is another AHA. It works as a type of chemical peel that exfoliates the skin by breaking down the molecules which hold dead skin cells together to loosens and lifts them off of your skin. By removing the outer layer of dead skin cells, the ingredient reveals lighter and brighter skin beneath. 

You can buy products containing glycolic acid over the counter. These are weaker concentrations that exfoliate the epidermis—the outer layer of the skin only. Stronger glycolic acid products that penetrate the deeper layers of the skin and target more stubborn dark spots are available by prescription through skincare professionals. 

If you’ve tried other options and your dark spots still aren’t budging, it might be time to turn to glycolic acid. But, as it’s a stronger ingredient, it’s not for everyone. You can speak with an experienced skincare professional to get the best advice for your exact skin type and if glycolic acid should be on your radar.

Vitamin C

Who’s it for? All skin types

Here’s one we’ve all heard about before. While we often turn to vitamin C when we’ve got a cold to boost our immune system, it’s helpful when treating hyperpigmentation, too.

Vitamin C, sometimes called ascorbic acid, is an antioxidant that combats free radicals. These are harmful molecules, like UV rays, which can damage skin and can cause hyperpigmentation. Vitamin C neutralises these to prevent further damage to the skin. It also works to reduce melanin production in the skin which stops more dark spots from appearing and lightens the appearance of existing discolouration. 


Licorice root extract 


Who’s it for? All skin types, even sensitive 

Product to try: ZO Brightalive Skin Brightener 

You may have only heard of licorice as a sweet, but it’s been used for medicinal purposes for years. Licorice root extract naturally contains an active ingredient called glabridin which reduces the production of melanin in the body. 

Without as much melanin, it's harder for the skin to create new dark pigment and worsen the appearance of hyperpigmentation. Licorice root extract also has anti-inflammatory and antioxidant properties that protect the skin from damage, help the skin recover and repair, and brighten existing discolouration.

Kojic acid

Kojic acid is derived from a fungus that is created when rice is fermented. Though often found in the food industry, kojic acid has huge potential in skincare, too. 

In order for melanin to form, it needs an enzyme called tyrosine. Kojic acid is effective at reducing the look of hyperpigmentation because it blocks the production of tyrosine. This means less melanin in the skin and less dark spots and patches on the surface. 

Just as with other acids, it also exfoliates by loosening dead skin cells which, in turn, reveals a brighter complexion beneath. Kojic acid also helps other ingredients in skincare products penetrate into deeper layers of the skin to target stubborn dark spots. 



Who’s it for? Lighter skin tones and oily and combination skin types. Hydroquinone can be an option for dry skin and darker skin tones but you should speak with a skincare expert first to be sure it’s right for you.

Product to try: Obagi Nu-Derm 3 Clear 

Hydroquinone is something of a controversial ingredient for hyperpigmentation. On one hand, it has been proven highly effective when reducing the look of dark spots and discoloured patches. On the other, there is a greater risk of the skin reacting causing post-inflammatory hyperpigmentation—essentially making the problem worse—and for areas that aren’t dark spots to be bleached. So, it’s worth proceeding with caution, speaking with a skincare expert and doing a patch text. 

Hydroquinone is another product that inhibits melanin production by blocking tyrosinase making dark pigments less visible. There are different strengths of hydroquinone available which range from 2% over the counter to over 4% by prescription.
