CBD topicals are designed to be applied directly to the skin. Riverbluff offers lotions, salves and roll-ons. Topicals are a great choice when it comes to treating localized pain or skin conditions. You will feel the effects in about 15 minutes. The effects will last 5-6 hours. The permeability of your skin is less relative to mucous membranes, like sublingual tissue. That means when using a topical product, you’ll want to choose one with a high amount of CBD and apply it generously.
