Hyperpigmentation is the term used to describe areas of uneven pigmentation in skin. 

Hyperpigmentation appears as darkened patches or spots on the skin that make skin look uneven. The spots are known as age spots or sun spots and hyperpigmentation is also at the heart of skin conditions such as melasma and post-inflammatory hyperpigmentation.

People with dark skin are normally more affected by hyperpigmentation marks than those with a lighter skin tone as skin pigmentation is stronger in dark skin.

Also known as chloasma, melasma is a condition where larger patches of hyperpigmentation develop mainly on the face. 

Although it can affect both men and women, melasma is most common in women and is thought to be triggered by changes in hormone levels.  Melasma occurs in 10–15 percent of pregnant women and in 10–25 percent of women taking oral contraceptives 1 and is sometimes referred to as “the mask of pregnancy”.

Sun exposure is the number one cause of hyperpigmentation as it’s sunlight that triggers the production of melanin in the first place. Melanin acts as your skin’s natural sunscreen by protecting you from harmful UV rays, which is why people tan in the sun. But excessive sun exposure can disrupt this process, leading to hyperpigmentation.

Once dark spots have developed, sun exposure can also exacerbate the issue by making age spots (or sun spots), melasma and post-inflammatory hyperpigmentation spots even darker.

Hyperpigmentation is also symptomatic of certain illnesses such as some autoimmune and gastrointestinal diseases, metabolic disorders and vitamin deficiencies. 

It can also be triggered by certain medications such as chemotherapy drugs, antibiotics, antimalarials and anti-seizure drugs.

Sun protection is the most significant step you can take in helping to prevent hyperpigmentation in the first place.  It’s important to remember that the sun’s rays affect skin even on cloudy days, so give your skin the daily protection it needs. As well as reducing hyperpigmentation, Eucerin Even Pigment Perfector Day Cream SPF 30 offers effective UVA and UVB (SPF 30) protection and prevents the formation of additional sun-induced pigment spots. 

Limiting skin’s exposure to the sun will also help to reduce instances of hyperpigmentation. Try to keep out of the sun during its most intense hours and wear protective clothing including sunhats and glasses whenever possible. When skin is exposed to the sun, apply and regularly reapply a sun protection product:
-  with a suitable SPF level
- which has been specially formulated for your skin type and condition

The Eucerin Even Pigment Perfector range has been specially formulated to reduce hyperpigmentation for more even and radiant skin. All four products in the range – a day cream, night cream, serum and spot corrector –contain Thiamidol®, an effective and patented ingredient that acts at the root cause of hyperpigmentation by reducing melanin production. It has been clinically and dermatologically proven to reduce dark spots and prevent their re-appearance. First results are visible from two weeks and improve continuously with regular use.

Furthermore, with SPF 30 and UVA filters, Eucerin Even Pigment Perfector Day Cream SPF 30 offers effective protection from the sun and prevents the formation of additional sun-induced pigment spots. 

Dermatological treatments such as chemical peels and laser therapy can help to reduce hyperpigmentation:

- Chemical peels involve applying a chemical solution to the face, neck and hands to exfoliate skin (remove dead skin cells), stimulate the growth of new skin cells and reveal new skin.

- Laser therapies have much the same effect, but tend to be more precise, as the dermatologist has more control over the intensity of the treatment. They involve ‘zapping’ the affected areas with high-energy light. The mildest treatments work just on the skin’s epidermis (surface layer), while more intense treatments can penetrate the deepest layers of the skin.

Dermatologists may also prescribe and/or use hydroquinone which is still regarded as the most effective topical agent for reducing hyperpigmentation. It can, however, only be used for limited periods of time because, like other forms of chemical peel and laser treatment, it can irritate skin and actually cause post-inflammatory hyperpigmentation, especially in people with darker skin.
