    GlossarySkin Permeation

    process where substances pass through skin into bloodstream

    Skin permeation, also known as transdermal absorption or percutaneous absorption, refers to the process by which substances pass through the skin and enter the bloodstream. This process involves the movement of molecules through the outermost layer of the skin (the stratum corneum), into the deeper layers, and eventually into the circulatory system. It is a critical concept in dermatology and pharmacology, particularly for the development of topical medications and transdermal drug delivery systems.

      community Does melatonin dissolve in isopropyl alcohol

      in Technology  7 upvotes 1 year ago
      The conversation discusses making a topical melatonin solution for hair loss treatment, questioning if isopropyl alcohol can dissolve melatonin. Melatonin is soluble in lipids and alcohol, but it's unstable and should be mixed fresh regularly; it may help hair growth by affecting certain cellular signaling pathways and has anti-androgenic effects.
