Acetyl tetrapeptisde-5 is a known humectant or hydroscopic moisturizer which helps reduce eye puffiness, improve skin elasticity as well as overall smoothness. This is done by attracting water from deep within in the skin to the outer-most layer of the skin (stratum corneum), taking advantage of this compounds hydroscopic properties (Making Cosmetics). Humectant rich formulas have also been used to treat xerosis (abnormally dry skin) successfully (PubMed). Humectants can also play an important role as emulsifiers within an overall formulation according to the Cosmetics Database.

Eyeseryl works in two ways. First, it inhibits glycation in the skin around the eyes. Glycation normally causes abnormal, disorganized cross-linking in collagen fibers. Rather than having all of your collagen fibers working together in a unified, organized fashion, glycation causes skin to be less elastic.
The second way Eyeseryl works is by changing the permeability of your blood vessels in the region. (Yes, this sounds scary, but it actually is no scarier than putting pressure on a wound - you are simply changing the circulation).
