Skin conditions are often complex, with various symptoms and causes. This article seeks to unravel three common skin conditions - eczema, psoriasis, and rosacea - shedding light on their symptoms, causes, and treatment options.
Eczema: More Than Just Dry Skin
Eczema, or atopic dermatitis, is a common skin condition characterised by dry, itchy, and inflamed skin. It's most common in children but can occur at any age. Eczema is typically long-lasting and tends to flare up periodically.
- Dry, sensitive skin
- Red, inflamed skin
- Severe itching
- Dark-coloured patches of skin
- Rough, leathery or scaly patches of skin
- Swelling, especially in the eyes
Eczema is thought to be driven by a combination of genetic and environmental factors and is often associated with other allergic conditions like asthma and hay fever. Treatment typically involves managing flare-ups, including emollients, topical corticosteroids, and lifestyle changes.
Psoriasis: When Your Skin Cells Grow Too Fast
Psoriasis is a chronic autoimmune skin disease that speeds up the growth cycle of skin cells, causing cells to build up rapidly on the skin's surface. The extra skin cells form scales and red patches that are sometimes painful and itchy.
Common signs and symptoms include:
- Red patches of skin covered with thick, silvery scales
- Small scaling spots
- Dry, cracked skin that may bleed
- Itching, burning, or soreness
While the exact cause of psoriasis is unclear, it's thought to be related to an immune system issue with T cells and other white blood cells in your body. Treatments include topical treatments, light therapy, and systemic medications.
Rosacea: The Relentless Redness
Rosacea is a chronic, inflammatory skin condition that primarily affects the face. It typically begins as flushing and redness on the central face and across the cheeks, nose, or forehead but can also less commonly affect the neck, chest, ears, and scalp.
Rosacea's symptoms include:
- Persistent redness
- Bumps and pimples
- Visible blood vessels
The cause of rosacea is unknown, and there is no cure. However, treatments can control and reduce the signs and symptoms. These include topical drugs, oral antibiotics, laser therapy, and lifestyle changes.
