You can buy some topical corticosteroids "over-the-counter" without a prescription. For example, for dermatitis, you can buy the steroid cream called hydrocortisone 1% from your pharmacy. Do not apply this to your face unless your doctor has told you to do so. This is because it may trigger a skin condition affecting the face ( acne or rosacea. ) Long-term use may also damage the skin. On your face this would be more noticeable than the rest of your body. So usually only weak steroids are used on the face. Those which are suitable are prescription-only.
If a steroid cream is purchased over the counter, the package should disclose the steroid used, and the strength, such as one percent hydrocortisone cream. Generally, the cream should not be used for more than a week, unless a doctor has specifically recommended an over the counter product for extended use. If the condition does not respond or grows worse, the over the counter cream should be discontinued, and an appointment should be made with a dermatologist , who can examine the site and prescribe a different medication or course of treatment.
