Seborrheic dermatitis: Why it should be treated early and how it is treated
- What is seborrheic dermatitis?


Seborrheic dermatitis is a form of eczema and a chronic inflammatory skin disease that occurs in areas with well-developed sebaceous glands and abundant sebum secretion. It often appears on the scalp, face, around the eyebrows, between the eyebrows, behind the ears, around the nose, on the chest, and in the armpits. In particular, many people suffer from seborrheic scalp dermatitis during the fall and winter because of dry weather.
Seborrheic dermatitis usually appears within the first 3 months after birth and between the ages of 40 and 70. It is one of the very common conditions, with 1 in 20 adults having seborrheic dermatitis.
Seborrheic dermatitis often repeats periods of improvement and worsening, and symptoms tend to last for a long time, so early treatment is important.
- Differences between acne and seborrheic dermatitis

Many people think seborrheic dermatitis and acne are the same condition, even though their causes, symptoms, and treatment methods are all different.
Acne often appears as small dark red bumps on the face and is frequently caused by hormones being stimulated by poor eating habits and lifestyle habits, excessive stress, and changes in the external environment, leading to excessive sebum secretion. In addition, only the affected area turns red, and when squeezed, yellow comedones appear.
Unlike acne, seborrheic dermatitis causes the surrounding area of the affected site to also turn red, along with white flakes. It may also come with a sensation of heat and itching. Another difference is that when squeezed, thick pus may come out.
- Causes and symptoms of seborrheic dermatitis

The exact cause of seborrheic dermatitis has not yet been clearly identified. However, based on the symptoms of seborrheic dermatitis, several causes are thought to exist, including family history with genetic factors, fungal and bacterial infections, and the effects of hormones or stress.
- Excessive sebum secretion
Seborrheic dermatitis tends to appear in areas where sebaceous glands are developed, and it mainly occurs during periods when sebum secretion is active, such as infancy and adulthood.
- Changes in temperature and humidity
Seborrheic dermatitis symptoms may worsen due to changes in temperature and humidity, such as in summer and winter.
- Abnormal reactions of neurotransmitters
In patients with neurological disorders, seborrheic dermatitis occurs more often, suggesting that abnormal reactions of neurotransmitters may play a role. The same reason explains why seborrheic dermatitis worsens when stress becomes severe.
- Increase in fungi and bacteria
Seborrheic scalp dermatitis may occur when fungi or bacteria increase in the skin, or when certain medications are used or nutritional disorders are present.
Seborrheic dermatitis caused by the above factors is often accompanied by itching, and redness, scaling, or crusting may appear. It may also be accompanied by redness, stinging, and weeping.
- Treatment methods for seborrheic dermatitis
Seborrheic dermatitis treatment is carried out using lasers, medications, or by changing the environment to aid recovery. If left untreated, it can spread to surrounding areas and is likely to worsen, so it is best to visit a hospital for seborrheic dermatitis treatment quickly. The treatment methods are as follows.
For treatment after onset, Icon Green, Vbeam Perfecta, and PlaDuo are effective.
- Icon Green
Icon Green induces regeneration deep within the skin and uses high power to deliver laser treatment to lesions of different depths. It has also been upgraded from existing fractional lasers, reducing the risk of skin damage with a stable cooling system and improving skin texture to create brighter skin.
- Vbeam Perfecta
Vbeam Perfecta minimizes stimulation to normal skin tissue, allowing for manageable treatment. It acts on inflammatory organisms in the skin and helps improve inflammation. Because it compensates for the shortcomings of existing Vbeam laser procedures, treatment without bruising is possible. It is also effective in improving red skin.
- PlaDuo
PlaDuo enables skin regeneration through dual plasma. It uses R Toning, which kills organisms on the skin and controls sebum glands to improve skin troubles, and N Toning, which promotes fibroblast collagen proliferation and regulates blood circulation in microvessels. Depending on the skin concern, special tips are used to treat skin conditions and induce skin regeneration for healthier skin.
In addition to laser treatment, medications may be prescribed to help recover from skin inflammation, and lifestyle habits and stress factors can be adjusted to remove factors that worsen dermatitis. Above all, it is important to provide enough moisture to the skin through proper use of moisturizers. In addition, hair and skin should be kept clean at all times, and in the case of facial seborrheic dermatitis or facial seborrheic dermatitis, it is better to avoid using oily ointments or cosmetics.
Seborrheic dermatitis, a chronic skin disease that occurs in areas with well-developed sebaceous glands and abundant sebum secretion, often repeats periods of improvement and worsening and lasts for a long time, so receiving treatment early is helpful. However, seborrheic dermatitis is not a life-threatening condition, so many people leave it untreated because they do not feel the need for treatment. If it is left untreated, inflammation can spread, and if it progresses to a severe state, it may lead to hair loss, so it is important to pay attention to management and treatment as soon as it is discovered.
