Sorry if it sounds like a not very educated question. Would silicones in a serum compromise absorption of active ingredients from a moisturiser applied on the top of the serum? I had an assumption that only very last product that is being applied to the skin should contain silicones, but recently I found a serum, that seems pretty well formulated, and it contains PEG-8 Dimethicone. My assumption is coming from the idea that products should be applied in order: from the lighter texture to heavier texture (essence, water-based serum, moisturiser etc.) and since silicones reduce TDWL they might reduce absorption of active ingredients from the next product. I understand that silicones don't form a "film" on the skin but still sounds a bit counterintuitive to me. I would really appreciate an opinion of professionals.
Thanks in advance.
