Psoriasis is a common skin condition that changes the life cycle of the skin cells that can affect anyone, although it is more common in people ages 15 to 35. Normally, the body naturally develops new skin cells every month to replace skin that sheds or flakes off. With psoriasis, new skin cells form within days rather than weeks. The skin cells build rapidly of the surface of the skin and form thick scales that are often itchy, dry and sometimes painful. Psoriasis is not curable, but the goal of treatment is to stop the skin cells from growing so quickly. The cause of psoriasis is unknown, but it is believed that the immune system and genes may contribute to the condition. The T-cells that normally fight harmful viruses and bacteria, may actually be attacking healthy skin cells, which can tell your body to produce more skin cells before the old skin is ready to shed. This results in the patches of skin. The scales can be treated with topical corticosteroids, moisturizers, salicylic acid and Vitamin D from natural sunlight or tanning beds.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
