Red spots on the skin. The spots in psoriasis have several modifications and their corresponding symptoms. With the most common vulgar psoriasis, the spots look like plaques that first appear as flat, clearly delimited erythematous maculae – round-oval, diameter less than 1 cm – or dense red papules that just rise above the healthy skin. Usually, they appear on such parts of the body like elbows, lower back, knees and also on the head (on the scalp), and then on any other areas of the body, but almost always symmetrically.

Change in the structure of the nail plate. Typical demonstrations are quite diverse. In general, it is very similar to the nail fungus. At the first demonstrations, the nail plate resembles a thimble. On the whole surface, it is observing bulged-in spots and furrows. They can occur immediately on all nails, or only hit one. In the beginning, changes are observed at the edge of the nail. Then spots and furrows gradually move to the root and change its color starts. The nail becomes dim and thickened. Further impairment of blood circulation only aggravates symptoms.

Dryness of the skin. Usually, a feeling of tightened skin arises around the elbows, face, and scalp. But the zones may be different; it can not be said that psoriasis appears only in the mentioned areas. In areas with dry skin, small rashes appear, which are delineated clearly from the surrounding skin and slightly elevated above it. Also there the emergence of scales on the superficies of the rash can arise. Forced removal of flakes is undesirable; it can lead to burning of the skin in this area and the creation of cracks.
