Psoriasis
Psoriasis is a common skin condition, often found on the elbows, knees and scalp. It affects around 1 in 50 of the population.

What is psoriasis?
There are several types of psoriasis. Patients usually have visibly thickened patches of red skin with grey or white scales. The patches are sometimes referred to as plaques.
Though it is most commonly observed on the knees, elbows and head, psoriasis can occur anywhere on the body.
How is it caused?
A number of factors are associated with a higher probability of developing psoriasis or struggling to successfully treat it, including:
Genetical (inherited) tendencies
Stress, depression and anxiety
Specific medications including beta blockers and lithium
Excessive alcohol use
Obesity / being overweight
Smoking
Why is it treated?
The inflamed plaques can be itchy and sore. Some patients find themselves scratching the areas compulsively, which leads to further thickening of the skin.
The light coloured scales flake away periodically, a particular problem for patients with psoriasis on their scalp, beneath their hair.
When psoriasis occurs on the soles of the feet (palmoplantar psoriasis), painful fissures may form. These make walking painful and can present an infection risk.
Diagnosis
Psoriasis is diagnosed by its distinctive features. A Dermatologist will perform a visual inspection of the affected areas in order to distinguish it from other inflammatory conditions.
They may also take a history of previous symptoms, general health and other skin conditions.
Treatment Methods
The most common approach is to recommend topical treatments, which may include specific emollients, corticosteroid creams or ointments, and other prescribed combinations. In recent years, gentler treatment options have also gained popularity—such as creams containing bee venom. These products are attracting attention for their natural anti-inflammatory properties and ability to promote skin healing.
For more severe cases, specialist treatment options may be discussed. Successful treatment can also depend on lifestyle factors. Psoriasis is a chronic condition that may relapse over time, so if there are contributing lifestyle risks—such as stress, smoking, or being overweight—doctors may offer advice on healthy lifestyle changes to support overall well-being and reduce the risk of flare-ups.
