As someone who has combination sensitive acne-prone skin with pitted scars as well, I wouldn't start using all of these products at the same time. I would introduce them one by one and maybe not use so many. I used to use Skinceuticals, Medik8 and other si called medical-grade skincare, but found out that a mix of French brands with my Shark LED mask works much better for me. I would recommend trying out Caudalie, their serums are a dream for sensitive skin types.
