Multifaceted Approach to Pain Relief (Why it's Dynamic)
TRP channels (including the pain-relevant TRPV1, TRPA1, TRPV3, etc.) are expressed in both the epidermis and dermis of human skin—not confined to a single layer. TRP? ----> These channels are sensory. (Think cold, warm, stinging, pain) They live within the skin layers. They are found on keratinocytes (non-neuronal skin cells) and on peripheral sensory nerve endings, plus some immune and adnexal cells. This distribution explains why topical CBD (which penetrates the stratum corneum into viable skin layers) can directly interact with them for localized pain, inflammation, and spasm relief, as discussed earlier (e.g., via TRPV1 desensitization and ECS modulation in the 2019 TMD trial) Source Paper 📃 in the comments 👇
