Many patients find a very strange situation is that when the progressive phase of psoriasis has passed, the erythema is light as red as in the past, the scales are also less, the disease enters the stationary phase, but the lesions (when the runny erythema) are larger and thinner, so patients are anxious, and even think that improper treatment aggravates the disease. This symptom presentation puts a great psychological burden on the patient. What happens when psoriasis patches get bigger and bigger? Psoriasis can be divided into three periods: the progressive phase, the quiescent phase, and the receding phase. The first time a person has a skin condition, the skin condition is slow to recede, and the skin condition is slow to recede if the person has been treated with Western medicine for a long time. The number of lesions is not significantly related. It is important for patients with psoriasis to understand psoriasis properly from all aspects. The treatment is based on the characteristics of the disease at different times. In clinical practice, we find that the fading phase of psoriasis is characterized by the fading of the old rash, the thinning of the scales, the shattering and even the disappearance of the old rash, the central fading of some lesions in the shape of a ring or semi-ring, or the splitting of a large area into many small pieces, and the fading of most lesions from the periphery, gradually shrinking, and finally becoming pale white pigmented hypochromic or dark brown pigmented patches. So, when psoriasis is about to fade, the red spots become larger is normal performance, patients do not have to worry too much. The actual fact is that you will be able to get a lot of people to do the job.
