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.

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.
Cocamidopropyl Betaine is a pH 4.5-5.5 liquid that is used to improve the overall efficiency of the formulation. It’s usually combined with different surfactants and is used because of its cleansing efficiency. It helps to remove sebum and dirt from the skin and hair. It also works as a foaming agent helping to make a pleasant foam.

Caffeine stimulates all the processes inside skin cells. It's very effective for reducing swelling on the face (especially great for under the eyes area). The effectiveness depends on the concentration, the more component you apply the better the effect will be.
It also tones up the skin making it look younger. It's great for dry skin because it stimulates the synthesis of cholesterol, a chemical that helps to form a protective layer on the surface of the epidermis.
Xanthan Gum is used as a thickener or rheology modifier and emulsion stabilizer. It doesn’t provide any notable skin-related effects and is used mostly for formulation purposes. It makes the product’s texture smooth and even. It’s a naturally-derived thickener. Notable fact: it can also be found in the food you eat every day, so it is 100% safe.
