Which skin condition is characterized by red, scaly patches and is often triggered by stress or environmental factors?

Psoriasis is characterized by the development of red, scaly patches on the skin, which can be quite noticeable and often occur on areas like the elbows, knees, and scalp. This autoimmune condition is not only influenced by genetic factors but can also flare up due to stress, environmental triggers, and other lifestyle factors. Understanding psoriasis is essential for recognizing its symptoms and implementing effective management strategies.

While eczema, rosacea, and acne vulgaris are all common skin conditions, they have different characteristics and triggers. Eczema typically involves dry, itchy skin and may be related to allergic reactions or irritants, rather than purely stress or environmental factors. Rosacea primarily presents with redness and visible blood vessels on the face and is more related to chronic facial flushing. Acne vulgaris is associated with clogged pores leading to pimples and is primarily influenced by hormonal changes and skin type rather than environmental stressors. Thus, psoriasis stands out due to its distinctive symptoms and the specific triggers that can worsen its appearance.
