From product name

Effective ingredients missing or their concentration is too low.

Aloe barbadensis leaf juiceEffect: LowTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~23–34%
GluconolactoneUnder-dosedA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~0.55–1.25%

Works

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: glycerin, aloe barbadensis extract.

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: caprylic/capric triglyceride, adansonia digitata oil.

Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~2.8–4.2%
Adansonia digitata oilKey active· EmollientEffect: HighBaobab oil. Helps soften the upper layer of the skin~1.9–2.9%
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~0.4–0.9%

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~0.5–1.15%
GluconolactoneUnder-dosedA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels.
