Seborrheic dermatitis presents as flaky scales accompanied by redness primarily affecting oily regions such as the scalp (dandruff), face near eyebrows/nose/nasolabial folds, ears, and upper chest. The exact cause involves an inflammatory reaction related partly to yeast (Malassezia species) proliferation on oily skin areas combined with individual susceptibility factors including stress or weather changes affecting severity levels over time.< / p > < ul >< li >The key signs include greasy scales accompanied by itching sensation that waxes/wanes particularly during colder months;< / li >< li >< strong >Diagnosis< / strong > relies mainly on clinical evaluation noting typical distribution pattern supported by ruling out other dermatoses;< / li >< li >< strong >Therapies< / strong > range from medicated shampoos containing ketoconazole/zinc pyrithione for scalp involvement alongside low-potency topical corticosteroids applied sparingly during active flares;< / li >< li >< strong >Lifestyle advice< / strong > includes minimizing irritant exposure using gentle cleansers/humidifiers helps maintain symptom control;< / li >< p >Despite its chronic nature seborrheic dermatitis generally responds well when managed correctly aiming at reducing fungal load & restoring barrier function thus preventing recurrence.< / p >

This pigmentary disorder causes brownish-grey patches mainly on sun-exposed areas of the face. It is more frequent among women and those with darker skin tones due to increased melanin production triggered by various factors.

• The hallmark feature is symmetrical hyperpigmented macules commonly appearing on cheeks, forehead, nose bridge, or upper lip.
• Main causes: hormonal influences (pregnancy or contraceptives), UV radiation exposure, genetic predisposition, and some medications can precipitate melasma development.
• A clinical examination usually suffices for diagnosis, occasionally supplemented by Wood's lamp inspection to assess pigmentation depth.
• Treatment strategies prioritize strict sun protection combined with topical depigmenting agents like hydroquinone or azelaic acid; chemical peels or laser therapy might be considered cautiously in select cases under professional supervision.

The condition tends to be persistent but controllable with diligent adherence to treatment protocols emphasizing prevention of further pigmentation exacerbation by sun exposure avoidance measures.

This common skin disorder affects hair follicles and sebaceous glands, leading to clogged pores and inflammation. It most frequently occurs during adolescence but can persist into adulthood.

• The main symptoms are pimples, blackheads, whiteheads, cysts, or nodules primarily on the face, chest, and back.
• Causes include excess sebum production, bacterial colonization (Propionibacterium acnes), hormonal changes, and inflammation.
• A dermatologist usually diagnoses acne by physical examination of characteristic lesions.
• Treatment often begins with topical agents such as retinoids or benzoyl peroxide; oral antibiotics or hormonal therapy may be necessary in moderate to severe cases.
• Lifestyle measures like gentle cleansing and avoiding pore-clogging products complement medical therapy.

A tailored approach focusing on reducing inflammation helps minimize scarring risks while promoting clearer skin over time.
