    GlossaryTopical Calcineurin Inhibitors (topical immunomodulators)

    medications applied to skin to reduce immune responses

    Topical Calcineurin Inhibitors (TCIs) are medications applied to the skin to reduce inflammation and immune responses. They work by blocking the activity of calcineurin, a protein that activates T-cells in the immune system, making them useful in treating conditions like eczema and vitiligo. Unlike corticosteroids, TCIs do not cause skin thinning, making them a safer long-term option for sensitive areas.

      Topical dutasteride is more effective than oral finasteride for male pattern hair loss, with fewer side effects. Some prefer oral treatments for convenience, while others use topical solutions like minoxidil and dutasteride, sometimes with microneedling, for better results.
