How Topical Corticosteroids Work
Topical corticosteroids work by entering skin cells and binding to specific receptors, which then move to the cell's nucleus. Here, they influence the activity of certain genes, either boosting or suppressing their function. This action results in the decreased production of substances that cause inflammation, leading to a reduction in redness, swelling, and discomfort.
Common Conditions Treated
Topical corticosteroids are used to manage a variety of skin conditions such as eczema, psoriasis, and allergic reactions. They help soothe irritated skin by alleviating symptoms like itching and redness. Doctors often prescribe them to control flare-ups, allowing patients to maintain healthier skin over time.
Choosing the Right Corticosteroid
The choice of corticosteroid depends on the severity and location of the skin condition. High-potency corticosteroids are typically reserved for severe conditions on thicker skin areas, while milder corticosteroids are used for sensitive areas like the face and genitals. It's important to follow medical advice closely to avoid side effects.
