So I see a lot of skin care lotion formulas add different types and size of hydrolyzed protein (from large like oats and wheat to small like silk protein), then there is dimethicone which is prevalent in several formulas.
Do these agents actually do anything? Is there much point to forming a "barrier" layer on the skin? What would such a barrier do? I like the idea of "locking in" moisture, but not sure what's hype and what's not.
If there are any natural (ish) agents that will effectively keep the skin moist for longer, let me know!
