What the product description says
“After Sun Soothing and Cooling Moisturizing Lotion”
From product name

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, caprylyl glycol.

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, sesamum indicum seed oil.

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~4.1–6.1%
Sesamum indicum seed oilKey active· EmollientEffect: HighA good moisturizing plant oil. Due to the high linoleic acid content, it helps soften the upper layer of the skin, reduce water loss and support skin barrier function~1.3–1.9%
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~1.5–2.2%
Isohexadecane· EmollientEffect: LowImproves the texture of the product and helps soften the skin. Helps oil and water mix together and can be used as a cleansing agent~0.55–1.3%
Isopropyl palmitate· EmollientEffect: LowHelps soften the upper layer of the skin and create a thicker product consistency~3.7–5.5%
Hydrogenated polyisobutene· Emollient, OcclusiveEffect: LowUsed to improve the product consistency and soften the upper layer of the skin~2.1–3.2%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.45–1.05%
Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~2.7–4%
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~0.1–0.45%
LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.4–0.95%
Aloe barbadensis leaf juiceEffect: Low, below effective doseTraditionally 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~1–1.5%
