4. There are different types of psoriasis. While most people get scaly patches on their knees, elbows or torso, it can also affect fingernails, scalp and even genitals.

6. A new drug is being touted as a ‘miracle’ treatment. Trials of ixekizumab found that it brought improvement in 90% of cases.
There are various ways to minimise symptoms and boost skin healing. Try these steps:
- Avoid harsh soap Try to do without soap altogether, and wash most areas simply with warm – never hot – water.
- Choose fabrics with care Natural fibres such as cotton and silk allow your skin to breathe. Avoid wool, which can scratch and irritate. Use detergents that are non-biological and unperfumed when washing clothes, towels and bed linen.
- Seek expert advice Ask your GP to refer you to a dermatologist, who may prescribe a topical medication for the skin (such as salicylic acid) or phototherapy (therapy using light).
