Hydroquinone in the battle against pigmentation spots

Hydroquinone is an effective ingredient that is often used in dermatological treatments to reduce pigment spots. This chemical agent suppresses the production of melanin in the skin and is used in the treatment of conditions such as melasma and post-inflammatory hyperpigmentation. Given the popularity of hydroquinone, it is of great importance to be well informed about its composition, how it works, and the possible risks associated with its use.

Recently, there has been increased attention to the safety aspects of hydroquinone, which has led to recommendations to use this ingredient more cautiously. It is important to understand both the benefits and possible side effects of hydroquinone in order to treat pigmentation problems in a safe and effective manner.

What is Hydroquinone?

Hydroquinone is an organic compound that is naturally found in some plants, but is generally synthetically produced for use in cosmetic and dermatological products. This ingredient is particularly known for its depigmenting properties.

It is typically produced through a chemical process where phenol, an organic compound, is treated with ammonia. This process transforms phenol into hydroquinone. After this conversion, the hydroquinone undergoes a purification process to remove any impurities, which is important to ensure a safe and effective quality for cosmetic use. It is then processed into various concentrations, depending on the intended use in skincare products. In dermatology, it is often used in concentrations ranging from 2% to 4% for over-the-counter products, and sometimes even higher, to effectively treat pigmentation issues such as dark spots, age spots, and melasma.

What does it do in your skin?

In practice, this means that hydroquinone works by inhibiting the production of melanin in the skin. Melanin is the pigment that gives our skin, hair, and eyes their color. Overproduction of melanin can lead to hyperpigmentation, where dark spots and melasma (also known as the ‘pregnancy mask’) can appear on the skin. It intervenes in this process by blocking the enzymatic activity of tyrosinase, an essential enzyme in the melanin production process. By suppressing the activity of tyrosinase, it effectively reduces the formation of excess pigment, giving the skin a more even tone. This makes it a powerful option for people suffering from unwanted pigmentation spots.

Beware – 2 Problems

Despite the effectiveness, there are some considerations for people with dark skin. Prolonged use of higher concentrations can lead to side effects such as exogenous OCHRONOSIS, a blue-black discoloration of the skin. Particularly on the cheeks, a sharply linear band can be seen. Excessive and prolonged use can cause uneven results, making some areas darker than others. For photos, see this publication.

However, there are concerns about the possible health risks of prolonged use, including an increased risk of SKIN CANCER. Scientists have found that exposure to hydroquinone is linked to a significant increase in skin cancers.

• Melanoma: People exposed to hydroquinone are three times more likely to develop melanoma.
• Non-melanoma skin cancers: The risk of non-melanoma skin cancers is 3.6 times higher
• All reported skin cancers combined: The total risk of skin cancer is 3.4 times higher

It is important to note that the greatest uncertainty in these findings is that it is not known how long and how consistently the patients used hydroquinone. This makes it difficult to get a complete picture of the risks, but the findings suggest that there is a significantly increased risk of skin cancer when using it.

Alternatives to Hydroquinone

The use of hydroquinone to reduce pigmentation spots is popular, but due to possible side effects and health risks, it is wise to look at alternatives. Fortunately, there are several safe and effective ingredients available that help even out skin tone and reduce hyperpigmentation. Here are some of the most effective alternatives:
