Melasma is a skin condition that causes a red, puffy appearance on your face. There are several causes for this condition and different treatments for it. But there are also some things that you can do to help prevent melasma. The first step is to avoid sun exposure, since the sun is responsible for 90% of the growth of melasma. Fortunately, there are some products that you can use to protect your face against the sun’s harmful rays.
Genetics
Melasma is a common skin disorder with a multifactorial pathophysiology. In addition to environmental factors, melasma may triggered by hormones or medication. An increase in the level of progesterone during pregnancy is known to trigger melasma. Other factors contributing to melasma include exposure to sunlight and sex steroids.
Researchers have discovered several polymorphisms in the VDR gene, which may contribute to melasma. However, the mechanism of the polymorphism’s effects not well understood. Nevertheless, the polymorphism is correlated with the risk of developing melasma. Therefore, further study is necessary to determine the influence of this gene on melasma.
Studies of genetics of melasma have shown that melanocytes tend to be hyperactive in patients with melasma. This may explain why some respond differently to standard melasma treatment. Some melanocytes are also known to affect by autophagy deficits, resulting in new treatments.
A recent study shows that the (tt) polymorphism of the VDR gene is associated with an increased risk of melasma. This polymorphism was significantly present in 26.7% of the melasma cases and in a larger proportion of the control group.
Observational studies show that people with melasma are more likely to have family members who suffer from the condition. They are also more likely to have a lower educational level. These findings suggest that the gene-environment interaction should explored in future studies.
Researchers also discovered that the level of melanogenesis in facial melasma is correlated with genetic ancestry. The expression patterns of the European and Asian populations were similar, but differences found between the two groups.
Several genes involved in melanogenesis are upregulated in melasma. These include genes affecting angiogenesis, lipid metabolism, and repair.
Sun exposure
When it comes to melasma, it is no secret that the sun is the main trigger for the disorder. Melasma, also known as hyperpigmentation, is a condition in which dark patches appear on the skin. It’s commonly found on the cheeks, nose, forehead, and upper lip.
As a result of the inflammation caused by UV rays, melanocytes in the skin begin to overproduce melanin. This results in the appearance of a tan. However, if the melanin breaks down, a dark discoloration may appear.
The cause of melasma is still unknown, but scientists believe it may be due to malfunction of melanocytes. These pigment-making cells located in the basal cell layer of the epidermis. They have receptors for hormones such as progesterone and estrogen.
Studies have shown that people who have darker skin are less prone to melasma. But women are much more likely to develop this disease than men.
Pregnant women and women taking hormone replacement therapy are at a higher risk. In addition, women with ultra-sensitive skin are more prone to developing melasma.
Some skincare products can also cause discoloration. Make sure you use a sunscreen with at least 30 SPF every day. Avoid harsh skincare products that can irritate the skin.
The risk of melasma increased in the summer, so you should wear a hat and sunscreen when you are outside. Also, avoid tanning beds.
Keeping your skin protected from the sun is the most important way to prevent melasma from reoccurring. There are many ways to do this. You can wear sunglasses to shield your face from the sun, or you can apply a protective face mask.
Over-the-counter products
Over-the-counter products for melasma are an effective, convenient way to treat this skin disorder. However, they are not as powerful as prescription medications. Therefore, it is important to follow your healthcare provider’s recommendations when using these products. They can help reduce the appearance of melasma, and they can also contribute to more even-toned skin.
Melasma caused by an over-production of pigment. This pigment made by a certain enzyme called tyrosinase. In the body, tyrosinase is the only source of melanin pigment. Using topical agents to reduce the production of this pigment can help to lighten melasma.
Hydroquinone is a well-known skin lightening medication. It is a commonly used melasma treatment. However, it may cause side effects if used for prolonged periods of time.
Another popular melasma treatment is azelaic acid gel. Azelaic acid is a natural acid that can diminish the appearance of dark spots. But it should used with caution because it can cause an allergic reaction.
Vitamin C is another antioxidant that helps to lighten melasma. In addition to its anti-inflammatory properties, vitamin C works to stimulate cell turnover and reduce the production of melanin.
Melasma is a common skin condition that is most common on the forehead, nose, chin, and arms. If you’re worried that you might have melasma, seek treatment from a board-certified dermatologist. He or she can help you determine the cause of your skin discoloration, and offer the right treatment options.
Some over-the-counter products for melasma include hydrocortisone, tretinoin, and azelaic acid. These creams usually applied once a day. You should avoid sun exposure and contact with soaps or other irritants.
Treatment options
Melasma is a chronic pigmentary disorder that is usually located on the cheeks, forehead, and neck. However, it can occur anywhere on the body. It can affect a person’s appearance and social life, which can lead to a lack of self-confidence and self-esteem.
Fortunately, there are treatments for melasma. These include topical and oral agents. Before you decide on a treatment plan, be sure to consult with your healthcare provider. He or she will be able to tell you if a certain medication is right for you.
Topical agents can use alone or in combination with a chemical peel. This helps to remove the top layer of skin and lighten hyperpigmentation. A chemical peel can be a safer option than laser therapy.
Laser therapies work by targeting the melanocytes, the cells that make the color in the skin. The laser’s light triggers the cells to reproduce, resulting in less pigmentation.
Another type of treatment is photoprotection. This includes UV blocking and healthy wavelengths of light. These wavelengths can rejuvenate the skin and help it heal.
If you are considering laser therapy, be sure to follow your healthcare provider’s recommendations for skin care. You should avoid harsh and damaging products and avoid the sun.
Patients with melasma should know that treatment will take time. While no cure exists, you should be able to get a significant improvement within a few weeks.
In addition to lasers and chemical peels, you can also use medical-grade skincare products to lighten hyperpigmentation. They include tretinoin and kojic acid. Retinoids encourage the turnover of dead skin and replace damaged tissue with new, healthier cells.
Signs and symptoms
Melasma is a common skin condition, especially among women. Although it’s a benign disease, it can affect self-esteem and confidence. Typically, the symptoms are mild and clear up on their own, but you can get treatment for them.
Melasma may appear as patches of blotchy, darker color on the cheeks, nose, upper lip, and neck. It can also occur on the forehead and shoulders.
Melasma usually develops over time. It’s not caused by physical discomfort or itchiness, but rather by chronic low-grade inflammation. Chronic low-grade inflammation has linked to cardiovascular disease and type 2 diabetes.
Symptoms of melasma vary from person to person. Some people have the disorder for their whole lives while others have it for just a few years. The disorder often triggered by hormone changes. For example, it can appear in a woman who is using birth control or other hormonal therapies.
If you have melasma, you need to be careful not to expose your skin to excessive sun exposure. This is particularly important during the summer months. Also, avoid tanning beds. Wear wide-brimmed hats.
The best way to prevent melasma is to wear sunscreen with a high SPF. Cover up when you’re in the sun, and try not to get too close to the rays.
There are several medications that can treat melasma. Most commonly, a topical cream or gel prescribed. However, if the dark patches don’t go away, you may need to use a prescription strength cream.
A biopsy of your skin sometimes needed to make sure that melasma is the reason for the discoloration. When the doctor does this, the results used to determine the best treatment.
