Skin Pigmentation and How Can You Improve It

Uneven pigmentation is one of the most common skin concerns I see in aesthetic and skincare practice.

It can appear as individual dark spots, larger patches or a generally uneven complexion. The underlying process is usually related to increased or uneven production and distribution of melanin, the pigment responsible for the colour of our skin.

Hyperpigmentation can affect every skin tone and can have many different causes. Importantly, it is not always simply a matter of "too much pigment". The type of pigmentation, its depth and the factors triggering it all influence how it develops and how difficult it can be to treat.

The good news is that many forms of pigmentation can be improved with a consistent and appropriately gentle approach. The key is not to attack pigmentation aggressively.

It is to understand why it is there, reduce the factors that stimulate it and gradually support more even-looking skin.

Common Types of Pigmentation

Post-inflammatory hyperpigmentation, or PIH, develops after inflammation or injury to the skin.

It can occur following acne, eczema, irritation, burns, procedures or other forms of skin trauma. PIH can occur in any skin tone, but it tends to be more persistent and noticeable in darker skin tones.

This is one reason why I am particularly cautious about recommending overly aggressive exfoliation or irritating skincare to pigmentation-prone skin.

If a product repeatedly causes burning or irritation, it may work against your goal of achieving a more even complexion.

Melasma is a chronic pigmentary condition that usually appears as symmetrical brown or grey-brown patches, most commonly on the cheeks, forehead and upper lip.

Hormonal factors can play an important role, which is why melasma is frequently associated with pregnancy and hormonal contraception.

However, melasma is multifactorial, and environmental factors, particularly sun exposure, are also important.

Melasma can be persistent, so I prefer to think of it as a condition that needs ongoing management, rather than a pigmentation problem that can simply be "removed".

Solar lentigines, often called sun spots or age spots, are flat areas of increased pigmentation associated with cumulative sun exposure over time.

They commonly appear on areas that receive more sun, such as the face, hands and décolletage.

This is why prevention is such an important part of pigmentation management.

What Can Trigger or Worsen Pigmentation?

There is rarely one single cause.

Some of the most important factors include:

• UV exposure
• Hormonal changes
• Inflammation and skin injury
• Visible light
• Heat and environmental factors
• Certain medications

UV exposure

UV radiation stimulates melanocyte activity and can contribute to both the development and persistence of pigmentation. Sun protection is therefore not simply an additional step when treating pigmentation — it is part of the treatment itself.

Hormonal changes

Hormonal changes can contribute to melasma, particularly during pregnancy and with hormonal contraception. However, hormones are only one part of a much more complex process.

Inflammation and skin injury

Acne, eczema, irritation, picking, burns and other forms of inflammation can leave pigmentation behind.

This is particularly relevant for people who are prone to post-inflammatory hyperpigmentation.

Visible light

Visible light can also contribute to pigmentation, particularly in melasma and in people with darker skin tones.

This is one reason why tinted sunscreen can be particularly useful for pigmentation-prone skin.

Heat and environmental factors

Heat may aggravate melasma in some people, although the relationship is more complex than simply saying that "heat causes pigmentation". Understanding your individual triggers is therefore important.

Certain medications

Some medications can cause photosensitivity or changes in pigmentation. If you notice new or unusual pigmentation after starting a medication, it is worth discussing this with your doctor rather than assuming that it is simply sun damage.

Which Skincare Ingredients Can Help?

There are many ingredients marketed for pigmentation, but I don't believe that the strongest or highest-concentration product is necessarily the best choice.

I prefer a gradual, barrier-conscious approach. At Nordelle Essence, we have selected ingredients with recognised roles in supporting a more even-looking complexion, while avoiding the idea that skincare needs to be unnecessarily aggressive to be effective.

Vitamin C

Vitamin C has antioxidant properties and can support a brighter, more even-looking complexion. It also interacts with pathways involved in melanin production. However, not all vitamin C products are formulated in the same way. Our Nordelle Essence Vitamin C Serum uses 2% ascorbyl glucoside, a stable vitamin C derivative, rather than a high concentration of pure L-ascorbic acid. It is combined with ferulic acid, sea buckthorn and hydrating ingredients.

I deliberately prefer a stable, moderate formulation rather than pursuing very high concentrations simply because they sound more impressive.

For me, effective skincare is about finding the right balance between efficacy, tolerability and long-term consistency.

More active does not automatically mean better skincare.

Niacinamide

Niacinamide, or vitamin B3, is a particularly versatile ingredient.

It can support the skin barrier, help calm inflammation and has been shown to interfere with the transfer of melanin-containing melanosomes to surrounding skin cells.

It is also generally well tolerated, making it a useful ingredient when pigmentation and sensitivity coexist.

Our Nordelle Essence Niacinamide Gel Moisturizer combines this ingredient with a lightweight moisturising formulation and is part of our pigmentation-focused collection.

Kojic Acid

Kojic acid is a well-established cosmetic brightening ingredient that can inhibit tyrosinase, an enzyme involved in melanin production.

It can be useful as part of a gradual approach to uneven pigmentation.

Our Nordelle Essence Kojic Acid Brightening Cream for Dark Spots is specifically formulated for this purpose.

Lactic Acid

Alpha-hydroxy acids can help exfoliate the superficial layers of the skin and improve skin texture.

Our Nordelle Essence AHA Peeling Concentrate contains 10% lactic acid.

This is an active treatment, however, and I recommend using it twice a week only, rather than exfoliating every day.

If your skin is sensitive or already irritated, even twice-weekly exfoliation may not be appropriate until the skin barrier has recovered.

When treating pigmentation, I would much rather see someone use an exfoliating product appropriately and consistently than over-exfoliate in an attempt to achieve faster results.

Sun Protection Is Essential

If there is one thing I would emphasise when discussing pigmentation, it is this:

You cannot effectively manage pigmentation while repeatedly exposing the skin to the factors that stimulate it.

Consistent broad-spectrum sun protection is an important part of preventing existing pigmentation from becoming darker and helping pigmentation-focused skincare work more effectively.

For pigmentation-prone skin, tinted sunscreen can provide an additional benefit because iron oxides can help protect against visible light, which may contribute to melasma and hyperpigmentation.

Sun protection is also about more than sunscreen. Hats, sunglasses, protective clothing and sensible behaviour outdoors all have a role.

I will be discussing winter sun protection in more detail in a separate Nordelle Essence article.

A Simple Approach to Pigmentation

I don't recommend trying to use every brightening ingredient at once.

A simple routine is often easier to tolerate and, importantly, easier to maintain.

Morning Routine

Gentle cleanse → Vitamin C → Niacinamide moisturiser → SPF

Our Vitamin C Serum provides antioxidant and brightening support, while niacinamide can support the skin barrier and help promote a more even-looking complexion. Finish with broad-spectrum sun protection.

Evening Routine

Gentle cleanse → targeted treatment → moisturiser

Depending on your skin and the type of pigmentation, this could include a product containing kojic acid or, twice a week, the AHA Peeling Concentrate with 10% lactic acid. You don't need to use every active ingredient every day.

If your skin becomes irritated, step back rather than pushing through it.

Inflammation itself can contribute to post-inflammatory pigmentation, so aggressive skincare can sometimes be counterproductive.

Be Patient With Pigmentation

Pigmentation rarely develops overnight, and it usually doesn't disappear overnight either. The time needed for improvement depends on the type and depth of pigmentation, your skin tone, the underlying trigger and how consistently that trigger is controlled.

Melasma in particular can be persistent and may require professional assessment and a combination of treatments.

This is why I prefer to think about pigmentation as long-term skin management rather than a quick fix.

• Protect the skin from further stimulation.
• Support the skin barrier.
• Use evidence-based ingredients consistently.
• And avoid creating unnecessary inflammation in the process.

Healthy-Looking Skin Is the Goal

When treating pigmentation, the goal shouldn't be to strip the skin or force it to change as quickly as possible.

The goal is healthier, more even-looking skin that remains comfortable and resilient.

At Nordelle Essence, this is the philosophy behind our pigmentation collection: doctor-led, evidence-guided skincare designed to support the skin rather than overwhelm it.

Healthy skin is not achieved through excess. It is built through consistency, balance and respect for the skin's natural function.
