The most common cause of blemishes is sunlight and the most common type of blemish is pregnancy spots.
Sometimes if you stand in front of a mirror and look at your skin, you will notice spots that you may not even know when and why they appear on your skin, which in many cases are not very difficult to prevent.
With Dr. Mohammad Ali Nilforuzadeh; We have talked about this by associate professor of dermatology at Tehran University of Medical Sciences and director of the Dermatology and Stem Cell Research Center.
Tell us about the most common cause of blemishes.
The most common cause of blemishes is sunlight, and the most common type of blemish is pregnancy spots, which are more common in women and appear symmetrically brown gradually. Some women who take birth control pills also get the same spots. Sometimes after pregnancy or discontinuation of the pill, the stain disappears, but sometimes it lasts for years.
Which blemishes appear from childhood?
Freckles appear from the age of 5 and are mostly seen on open parts of the body. This type of blemish is more common, especially in people with fair skin and red hair or blue eyes, and becomes brighter with age. Although fleas and ticks are aesthetically annoying, they do not pose a health risk.
Which blemish appears in old age?
Aging spots, as their name implies, appear after prolonged exposure to sunlight and aging. These spots are flat and brown on the face and back of the hands, and over time they become bolder and wider and should be examined because they may turn into malignant lesions.
Does nutrition also affect the incidence of blemishes?
Yes, some spots are caused by vitamin B12 deficiency. These spots are more common in people with dark skin. Vitamin A deficiency, folic acid and anemia can also cause this problem.
What is the treatment for skin blemishes?
In the treatment of some skin blemishes, the use of exfoliators or surface chemical peels in appropriate doses is recommended. The use of anti-dandruff medications or brighteners that contain coloring compounds such as hydroquinone and corticosteroids can also be effective. Sometimes topical treatments are not enough and require laser or subcutaneous treatments.
In this case, be sure to consult a dermatologist because the correct choice of parameters is very important. It should not be prescribed by non-specialists to remove the stain because some inappropriate measures will make the stain last longer and thicker. All topical and laser treatments should be selected according to the patient’s condition, skin color, and the extent and depth of the stain. During the treatment, concealer creams should be used so that the person is not visually upset and the treatment process is completed. Skin blemishes are more common in people with fair skin and eye color and those with red hair.
What about medicines? Can they cause stains?
Yes, many people say they protect their skin from the sun but do not know the cause of the blemish. Some medications, such as birth control pills, anti-malarial pills, and some psychiatric medications, can cause the skin to turn brown or dark blue. Chemotherapy and lightening medications can also cause blemishes.
Is it true that it is said that freshly healed wounds should also be treated with sunscreen because the sun causes blemishes on the wound?
Yes, some blemishes are caused by inflammation of the skin. The skin of people with acne becomes sore, or their pimples are manipulated, they have lupus, or their skin is abraded, or they have a laser that darkens if they are exposed to sunlight. People who bag their face may also get blemishes by repeating this habit.
What about diseases?
Disease can also cause blemishes. It causes skin diseases such as asthma, liver and lung problems, rheumatism and dark spots.
Could the job also have an effect on the formation of skin blemishes?
Yes, for example, job blemishes are caused by skin contact with asphalt or oily compounds and sunlight. These spots should be examined by a doctor and, if necessary, sampled and treated. Sometimes pads and colognes cause stains. When certain chemical compounds in perfumes and colognes are sprayed on the skin, they cause dark spots. This problem is especially common in men who spray cologne on the neck or behind the ears.
Can stains be prevented?
For some spots, yes, but others, such as fleas and ticks, are genetic and have no way to prevent it. Stains caused by drugs or diseases can not be prevented unless the cause of the disease is eliminated. Most medications should also be taken at night to avoid photosensitivity.
One of the most important ways to prevent many blemishes is the frequent and regular use of sunscreen, which should be used according to the SPF and the type of skin. Avoiding too much sunlight, especially between 10am and 4pm, and wearing the right cover, such as a hat and sunglasses, can help. Chemical compounds should not come in direct contact with the skin, and if you are in contact with them due to your job, you should use protectors such as gloves and masks. Perfume should also be sprayed on clothes.
