Psoriasis
Psoriasis
Psoriasis is a genetically determined, inflammatory skin disease in which skin cells reproduce faster than normal. It is a common condition with dull red plaques with silvery scales that most commonly develop on the elbows, knees, scalp, or hands and feet. A normal skin cell matures and falls off the body’s surface in 28 to 30 days, but a psoriatic skin cell takes only 3 to 4 days to mature and move to the surface. Instead of falling off, the cells pile up and form the lesions.
Exacerbating factors and triggers of psoriasis
- Skin or systemic infections, e.g., streptococcal pharyngitis
- Skin injury from cuts, scrapes, or burns
- Certain medications, such as beta-blocking agents, antimalarials, and lithium
- Emotional stress and anxiety
- Smoking and drinking alcohol
- Hormonal changes
- Rubbing and scratching due to itching
Types of psoriasis
- Plaque – the most common form, characterized by raised, inflamed, red lesions covered by a silvery white scale
- Guttate – characterized by small, raindrop-like lesions
- Pustular – characterized by weeping lesions and intense scaling
- Inverse – characterized by intense inflammation
- Erythrodermic – characterized by intense shedding and redness of the skin
Treatment options include topical or oral medications, biologic agents that work by blocking the activation of the cells that trigger the development of psoriasis, and light therapy. Call Absolute Dermatology & Medi-Spa in Cedar Park, TX, for effective treatment of psoriasis.
