Seborrheic dermatitis (SD) refers to chronic inflammation of the skin that causes the formation of scaly patches, red skin and dandruff. It usually occurs in the scalp but it can also appear in other places such as the beard, eyebrows, chest, mid-face (on the sides of the nose) and ears. For some, dandruff and itchiness aren’t that bothersome to them. However, drying of the skin and prolonged scratching may break the skin’s integrity, opening the possibility for secondary bacterial infection. This situation can cause an increase in redness, production of exudate and local irritation.
In fact, SD can be more than just itching, redness and scaly skin. Just like an evolving mole, SD can be an indicator of a more serious disease. Studies have found that this skin condition is more prevalent in immune-compromised patients such as HIV/AIDS patients. Most people who have been infected with the virus rarely experience any signs and symptoms in the first 5 years. This causes them to believe that they are healthy – running the risk of transmitting the virus to others. Therefore, take heed of the early warning signs of SD and visit a doctor immediately to have yourself properly screened, especially if you have other risk factors such as sexual promiscuity and use of intravenous drugs.
Acne
Acne, also known as acne vulgaris, is a skin condition that occurs when your hair follicles become clogged with dead skin and oil (sebum), leading to inflammation. The oil-producing glands under your skin are called sebaceous glands, while the holes in your skin are called pores. The hair follicle is what connects your pores to the sebaceous glands. An inflammation would occur due to the colonisation of the clogged hair follicles by Cutibacterium acnes (C. acnes) bacteria.
Acne can affect the facial area, shoulders, back and chest. For the most part, acne deals a bigger blow to one’s self-esteem compared to their physical health. In the long run, unaddressed acne problems can lead to visible and long-term scarring. This exacerbates the self-esteem problem and predisposes a person to social anxiety, panic disorder and depression.
