[Routine Help] How many products can you apply in your routine with them still being effective? (I just hauled a bunch of The Ordinary products)

Beauty Tips For Body Care
So... I went crazy and hauled a ton from The Ordindary (again). I did get similar products, but a lot of it I wanted to try without waiting to use something up. I know some basic routine rules like water products before oils and, like toner > exfoliating acids > treatment > moisturizer > sunscreen > primer.I'm wondering how many products I can use and still have things be effective though, like when layering and such. I know Korean routines have like 10 steps, but that's extreme and I doubt things even do anything after that many layers. The Ordinary recommends "3 serum formulations in a single regimen" but do they mean treatments like Vitamin C or Retinoids, or 3 products max? What are your experiences?Here is what I have, in addition to my previous products:100% Organic Cold-Pressed Rose Hip Seed Oil100% Plant-Derived SqualaneAdvanced Retinoid 2%AHA 30% + BHA 2% Peeling SolutionAscorbyl Glucoside Solution 12%Azelaic Acid Suspension 10%"Buffet" (will probably give this away as a gift though, probably should have bought 2 lol)Caffeine Solution 5% + EGCGHyaluronic Acid 2% + B5Lactic Acid 10% + HA 2%Magnesium Ascorbyl Phosphate 10%Matrixyl 10% + HA (I give this to somebody but they may stop using it and give it to me)Natural Moisturizing Factors + HASalicylic Acid 2% SolutionVitamin C Suspension 23% + HA Spheres 2%
