But now, you add a capacitor. When you apply voltage, current still flows into the capacitor. But when the „outer“ voltage gets lower, below the voltage the capacitor was charged to, the current flows in the opposite direction, even though the outer signal should still move current into the original direction.

Generally, no. However excessively high charging and discharging currents can generate heat in the capacitor body, and the thermal expansion and contraction can cause degradation over time. If the capacitor is sized for the job, and charge/discharge rate is limited to avoid rapid heating, then the capacitor should last indefinitely.
