Do you want actives released when they are needed the most?
3. Triggered release.
Triggered release ensures that effective levels of active ingredients reach the treatment areas when they are needed most. The trigger can be the user rubbing the product onto the skin or several kinds of environmental factors including moisture, heat, friction, and change in pH levels.
Another useful trigger method is release by enzymes that can be found in areas of inflammation. When triggered by enzymes, the active ingredient goes to work directly in the area of need, instead of being wasted in an area where help isn't required.
