Dysport

Dysport typically lasts about three to four months, though this varies with dose, muscle strength, and metabolism. Fifty units split between the forehead and the 11s is a modest dose overall, so you may find the effect softens a bit sooner than someone treated with a heavier concentration, particularly at the glabella where stronger muscles often need more product to fully relax.

Dysport works by blocking nerve signals to the muscle, and its maximum effect shows around two weeks. If you're feeling heaviness in the forehead rather than smooth relaxation, that's often a sign too much was placed there relative to the 11s, which can throw off the balance between the two areas. There's no way to speed up metabolism of the toxin once injected. Follow up with your injector when it starts wearing off so the ratio between forehead and glabella can be adjusted next time. A board-certified plastic surgeon can help fine-tune dosing based on how your muscles responded this round.
