Although the major aims of both dermal fillers and Botox is to reduce appearance of wrinkles majorly as a sign of aging, the mechanisms of action of both interventions are quite different. While Botox as a muscle relaxer aims to decrease the appearance of wrinkles by paralyzing the muscles responsible, dermal fillers are injected to fill the line or crease in the face. This results in a near complete disappearance of the wrinkle hence making it a better option than Botox injections.
Dermal fillers also provide a longer lasting solution to facial wrinkles as they could last for a year or two before they are fully absorbed by the skin. Botox injections on the other hand only last for an average of six to eight months.
The differences cited above does not imply that both interventions are mutually exclusive. Botox injections are said to be ideal for ‘expression lines’ while dermal fillers are ideal for ‘static lines’. AT some point in time, distinction between expression and static lines may prove difficult as expression lines tend to evolve into static lines. Thus, some individuals may need to combine both Botox injections and dermal fillers to achieve the best results.
