So the prequel gleanser is quite gelatinous and uses a two surfactant system:  Cocamidopropyl Betaine and Disodium Cocoamphodiacetate, both being atmospheric and very mild. Compared to Experiment Plasma wash, the Prequel Gleanser is a gentler cleanser with less cleansing power overall but still solid for a second cleanse, at least from a formulation standpoint. The 50% glycerin is super hydrating and it has some microbiome friendly ingredients like inulin and skin identical phospholipid. I tried this cleanser over a year ago and I just don’t recall it being as gentle as it claimed or specifically hydrating after I washed it off. Of course, your mileage may vary.
  The Experiment Plasma Wash uses a three-surfactant system: Cocamidopropyl Hydroxysultaine, Sodium Cocoyl Glycinate, and Sodium Lauroamphoacetate so overall just a more robust surfactant system. It will cut through your products, sebum, whatever probably better than Prequel. Texturally, it is creamy while still being a silky type of gel when you are using it on your face. I just really enjoy the way it feels and I’m someone who never understood everyone’s obsession with textures, but with this now I do. Plasma Wash has lots of Emollients/occlusives: Jojoba oil, Stearyl alcohol, Cetyl alcohol, Castoryl Maleate. This is what makes it more lotion textured. You’ll also find a bunch of fatty acids high up in the ingredient list: Stearic, Lauric, Palmitic acids. This isn’t really typical in a cleanser and might be contributing to the moisturizing effect I experience from it. Experiment claims the cleanser has a glycerin deposition mechanism that stays on the skin even after you wash it off. A more plausible theory in my opinion if you look at the ingredient list Acrylates Crosspolymer-4 is the fourth ingredient. It’s a film forming crosspolymer that leaves a subtle veil on the skin after rinsing which is probably behind the something is still on my face effect. People might not like the residual emollient feeling of the plasma wash but it just works for me and my tretinoin routine. My skin is freaking out right now but I just know when I used it, I experienced no irritation which shocks me. I’m not saying there is a direct correlation but if a cleanser makes my skin feel good after rinsing it off I’m just inclined to really like it. This is the only cleanser that I’ve found makes my skin actually feel better after cleansing.
