Psoriasis is a skin disease that affects the life cycle of the cells of the skin. It causes silvery scales and patches of red, dry skin. According to the Mayo Clinic, psoriasis is a chronic disease that may have periods when symptoms worsen. It can also go into remission, with symptoms disappearing for a while. Salicylic acid is one of the drugs used to treat psoriasis.
Explanation
Psoriasis is an overgrowth of skin cells, and salicylic acid works directly on that problem. It softens these scaly, dry or thickened skin patches, making them fall off more easily. After salicylic acid use, the patient may be left with fresh skin without symptoms or noticeable psoriasis. That does not mean, however, that psoriasis won't return and need additional treatments with salicylic acid.
Formula
There are a number of products available with salicylic acid that work for psoriasis. They are all topical and in lotion, gel, cream or shampoo formulas. The stronger concentrations of salicylic acid need prescriptions, but over-the-counter products are available. Some of these products contain other active ingredients. Coal tar and topical corticosteroids can be added in addition to salicylic acid to increase the effectiveness of products.
Application
Apply topical salicylic acid only to skin that is affected by psoriasis. Unless a health care professional specifically tells you to, do not bandage or cover the area where the preparation has been applied. Shampoos with salicylic acid are used to treat psoriasis of the scalp and should be applied as you would normally use shampoo. Continue the treatment as directed. It may take more than a month before you see the benefits of treatment.
Considerations
According to MedlinePlus, salicylic acid allergies are possible, so seek medical attention if you have any unusual swelling, rashes or difficulty breathing. Other topical products may interfere with salicylic acid, so consult your pharmacist before using additional cleansers or lotions. Salicylic acid products are not recommended for women who are pregnant or breast-feeding.
Warning
Salicylic acid is medication and requires certain precautions. Do not put topical salicylic acid on skin that is irritated or infected. Use caution when applying salicylic acid so you do not get it in your mouth, nose or eyes. According to Drugs.com, if you do accidentally get some of the lotion in those areas, flush them with water for 15 minutes. Never swallow salicylic acid in any form.
