Skin hyperpigmentation is a common occurrence, and in most cases, you can manage it easily. However, in some cases, hyperpigmentation can become a problem, and self-treatments may not be effective. In this blog post, we will explore the causes of hyperpigmentation, signs of hyperpigmentation, and how to manage hyperpigmentation.
Let’s get started!
What is skin hyperpigmentation and how is it different from freckles?
Hyperpigmentation is a skin condition that causes brown spots to appear on your skin. It is most common in people who have light skin, but people of any skin tone can develop the condition.
The condition occurs when melanocytes, the cells that color your skin, are over stimulated and are more likely to form sunspots.
Freckles are the most common type of hyperpigmentation. These small spots can appear on nearly any part of the body and are more common in people with light skin.
One type of hyperpigmentation is melasma, which is a type of facial hyperpigmentation. This pigmentation typically develops during pregnancy or triggered by stress and anxiety. It is more common in people who have darker skin.
Another type of hyperpigmentation is melisma, which is a skin condition that frequently develops in tropical climates because skin is more susceptible to sun exposure. It frequently affects areas of the skin that are most exposed to the sun, such as the face, neck, chest, and shoulders.
Treatment options are available to help combat these skin conditions.
What are the different types of skin hyperpigmentation?
There are several types of hyperpigmentation which appear on the skin.
The first type of hyperpigmentation is called the Melasma, which usually occurs over the cheeks, forehead, chin, upper lip, and nose. The cause of Melasma is hormonal.
The second type of hyperpigmentation is called the post-inflammatory hyperpigmentation, which affects people who’ve received acne over a short period of time. The cause of this hyperpigmentation is damage to the skin, which can be caused by sun exposure.
The third type of hyperpigmentation is the lentigo reticularis, which shows up as brown marks on the skin and is caused by sun damage. The lentigo reticularis is a gradual type of hyperpigmentation, which means it can take up to 3 months or a year for it to appear on the surface of the skin.
The fourth type of hyperpigmentation is the nevi, which is also caused by sun damage but shows up as dark spots on the skin.
The fifth type of hyperpigmentation is the red spots, also known as telangiectases. These spots are red in color and are mostly triggered by hormonal changes. The sixth type of hyperpigmentation is mottling, also known as vitiligo, which is when white spots appear on the skin.
The seventh type of hyperpigmentation is the freckles, which appear due to sun exposure.
The eighth type of hyperpigmentation is the melanin, which is the result of increased melanin production. The ninth type of hyperpigmentation is age spots, which appear on body areas like hands, face, and arms. The tenth type of hyperpigmentation is chloasma, which affects people who live in extremely sunny climates.
What are the causative factors for hyperpigmentation?
Hyperpigmentation, also known as melasma or chloasma, is the appearance of dark spots on the skin. It can occur in 4 forms:
Essential, superficial, and mixed types: The appearance of the spots differs depending on the skin type. Individuals with sensitive skin have a more noticeable reaction to the sun, and their skin is more easily damaged. This explains why the development of spots is more rapid, and sometimes more extensive in these areas. On the other hand, those with resilient skin may rarely develop hyperpigmentation, and have less evident skin damage, so the spots are fewer and minor.
Environmental and genetic factors can cause mixed types of pigmentation. You may find pigmentations at the face, neck, chest, forearms, and hands.
Age-related pigmentation. Aside from the damage caused by the sun, the aging process is another factor that results in hyperpigmentation. The skin starts to lose its elasticity and becomes thinner and thinner, which leads to the appearance of pigmented areas. These areas may be brown, tan, or blue in color. As time passes, discoloration becomes more pronounced, resulting in the appearance of dark spots and discolored patches.
HIV infection. Individuals with HIV infection and AIDS can develop hyperpigmentation due to the increased level of infection-fighting antibodies (known as antibodies) that target and destroy their healthy cells. The production of these antibodies weakens the structural integrity of their skin, causing the skin to become dry and thin. When this happens, the dark spots gradually darken. Severe damage causes long-term discoloration and irregular pigmentation.
Pigment changes due to medication usage. Certain medications and antibiotics may cause hyperpigmentation, especially if they affect the immune system. Some drugs can also interrupt tyrosine metabolism (a substance required for melanin production).
What are the main treatment options for hyperpigmentation?
Hyperpigmentation can be a difficult condition to manage, but there are a variety of ways that patients can try to reduce their hyperpigmentation. Here are some of the treatment options that patients can use to reduce their hyperpigmentation:
Hydroquinone – Hydroquinone is one of the safest treatment options for hyperpigmentation. Hydroquinone is available at various strengths (e.g., 2% and 4%), but in concentrations larger than 2% it can cause harmful effects on patients’ skin. It’s often best for hyperpigmentation patients with light skin types.
Retinoids – Retinoids are another effective treatment option for hyperpigmentation. Retinoids are available in many forms, including creams, lotions, and gels. Products containing tretinoin or retinol tend to be the most effective, although the National Eczema Association does advise patients to avoid products with tazarotene because patients often experience redness and irritation after using it.
Vitamin C – Vitamin C, or ascorbic acid, is another effective treatment option for hyperpigmentation. Vitamin C is available in a variety of topical formulations, including creams, lotions, gels, and serums. Clinical studies have shown that vitamin C is an effective option for hyperpigmentation.
Kojic acid – Kojic acid is a topical treatment option for hyperpigmentation that works by suppressing the production of melanin. This can provide patients many benefits, including reduced skin discoloration, less likelihood of acne breakouts, and improved skin tone.
Glycolic Acid – Glycolic acid is another treatment option for hyperpigmentation patients. Glycolic acid works by reducing skin pigmentation and improving your skin’s ability to absorb moisture. It’s often most effective when used in combination with other treatments such as tretinoin and hydroquinone.
Hyperpigmentation: What are the complications ?
Hyperpigmentation, also known as melasma or melasma treatment, is skin darkening.
There are a number of factors which contribute to hyperpigmentation. These factors may include:
Sun Exposure: The UV rays in sunlight increase the pigmentation in the surrounding tissue by oxidizing melanocytes in the basal layer of the skin.
Pregnancy: The ovaries secrete androgenic hormones which cause the transformation of melanocytes in the epidermis to dark pigment cells.
Common Medications: Oral contraceptive pill, estrogen replacement therapy for menopause and anti-seizure medications can trigger Melasma.
Skin Diseases: Skin diseases such as dermatitis or psoriasis can cause an inflammatory response in the skin, which may result in the deposition of melanin.
