INCI - Full Breakdown
Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.

Polysorbate 20 doesn’t have any notable skin benefits but is used in cosmetics quite often. Manufacturers use it for formulation purposes. It improves the scent, texture, and feel of the product.

Glycerin is one of the most outstanding and helpful skincare components. It's used in many skincare products because it works and provides notable results. It's one of the best moisturizers. Molecules of Glycerin can absorb water and deliver it into deep layers of the skin making it hydrated.
Citric Acid is one of the AHAs and it is a super useful component! It’s a great antioxidant. It acts as a soft peeling that removes dead cells and kills bacteria. It becomes even more effective if used with other cosmetic acids. Combined formulations are more active, but can irritate sensitive skin if used too often. The component can also whiten the skin and remove dark areas.
It can be an irritator due to its naturally lower pH level of 2.2. But manufacturers also use it as a pH adjuster so in most cases you will not have any issues.
Hexylene Glycol is mostly used for formulation purposes. It’s a good surfactant, emulsifier, and viscosity-reducing agent. It maintains the density of the formulation of the product preventing it from separating. It also makes the product feel better.
