Essentials recommendation - Germany

Hi! I'm currently based in Germany, but I'm leaving in two weeks. Since skincare is more affordable here, I'd like to take some essentials with me. What are your must have's from DM or Rossmann?

For example, I know I'll take the geek and gorgeous melting balm and the barrier cream and Balea's hypochlorous acid spray. I'm looking for recommendations for treatment serums (redness, oiliness, mild acne) and face wash.

Thank you!
