Psoriasis
Psoriasis covered with silvery-white scales - Latest treatments and coverage under national health insurance.
It doesn't spread, and the treatment has improved significantly.
Psoriasis is a chronic skin condition caused by immune system dysfunction, characterized by the rapid growth of skin cells that form red patches covered with silvery-white scales. It commonly occurs on the knees, elbows, scalp, and buttocks, and is not contagious.
- It can be easily confused with eczema or athlete's foot, so please consult a dermatologist for diagnosis before attempting self-treatment.
- Treatment progresses in stages: topical medications → phototherapy → oral medications → biological agents (injections).
- Severe psoriasis may qualify for special coverage, which significantly reduces the cost of expensive injection treatments – check with your dermatologist to see if you meet the criteria.

It's not just a disease of the skin.
Some patients with psoriasis experience psoriatic arthritis, which causes swelling and pain in the joints of the fingers and toes. If you experience stiffness in your joints in the morning or notice that your fingers are swollen like sausages, be sure to mention it – early treatment is crucial to prevent joint deformities. It is also related to obesity and metabolic syndrome, so weight management can help improve skin conditions as well. Because new lesions tend to appear on areas that have been scratched or injured, avoid excessive scrubbing or exfoliation.
Frequently asked questions
Can psoriasis be completely cured?
Since it is a chronic condition, the goal is not necessarily complete cure, but rather "maintaining clear skin." With the advent of biological agents, many patients are now able to maintain a state with minimal lesions.
Can I use steroid ointment for a long time?
If used according to the area and strength, it is safe, but applying strong creams for a long time to the face or areas prone to wrinkles can thin the skin. Be sure to use it as directed by a dermatologist, and if your condition improves and then worsens repeatedly, consult with them about advancing the treatment stages.
