The DarkSide program is a direct dark matter search experiment that uses argon as the target material. Exploiting the ionization signal from a dual-phase time projection chamber (TPC) filled with low radioactivity argon from an underground source, the preceding experiment, DarkSide-50, has set the strongest limit against WIMP with a mass in the GeV/c2 region. A new analysis has recently been carried out with a larger exposure coupled with an improved understanding of the detector response. In this talk, I will present the details of the updated search for light dark matter. I will also highlight latest studies to mitigate remained backgrounds and give prospects on future experiments.
