What the product description says

“The tinted lip balm is infused with hyaluronic acid to boost moisture and offer a plumping effect.”

Source: Lookfantastic

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": sodium hyaluronate, butylene glycol.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.1–0.35%

Diisostearyl malateKey active· EmollientEffect: MediumHelps to soften the upper layer of the skin~0.15–0.65%

Ethylhexyl palmitateKey active· EmollientEffect: MediumAn emollient that helps soften the skin and create a nice product texture~0.15–0.65%

Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~0.1–0.45%

Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.15–0.6%

Octyldodecanol· EmollientEffect: LowAn emollient that helps to soften the skin and create a pleasant product texture and stabilize the formulation~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~0.1–0.45%

LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.15–0.7%
