What the product description says

“Green Tea Oil-Free Moisturizer”

Source: boscia

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: betaine, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, simmondsia chinensis seed extract.

DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~5.6–8.3%

BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~0.15–0.65%

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~0.15–0.5%

Lactobacillus fermentKey active· HumectantEffect: HighA fermentation product created by bacteria Lactobacillus. The fermented product has anti-bacterial properties and might be helpful in calming down inflammation, but studies are lacking. Helps attract water to the upper layer of the skin. Can be used as a preservative~0.95–1.45%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.15–0.6%

TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.15–0.55%

Camellia sinensis leaf extractEffect: Low, below effective doseCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.45–1.05%
