Plaque psoriasis is the most common form of psoriasis, making up approximately 90% of all cases of the skin condition. Psoriasis is an autoimmune disorder in which the immune system is tricked into believing that the skin itself is a threat, so in response the immune system gets into gear and tries to quickly grow new and healthy skin cells.

Eczema is a skin condition characterized by itchy, red patches that show up on various areas of the body, in response to skin irritants, dryness, allergies or even stress. Anyone who suffers with the condition would gladly welcome relief to the incessant itching and unsightly scabs and scales it produces on the surface of the skin. The primary way to fight eczema is to keep the skin moisturized and hydrated, because dryness is largely the reason eczema thrives.

Rashes may spring up every now and then as a simple reaction to some minor irritation like an insect bite or a new detergent. Rashes can also be the result of an infection, allergic reaction, autoimmune disorder, dry skin, hormonal imbalances, or any number of things. Some rashes itch quite a bit, while others do not.

Winter chill, cold winds and dry air can be quite a rude awakening for the skin. When the body is used to warmer weather and more humid conditions the rest of the year, the sudden shift to cold, dry conditions begins to affect the surface of the skin.
