What the product description says
“Moisturizing Lip Balm”
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: sodium hyaluronate.

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: simmondsia chinensis seed oil, diisostearyl malate.

Simmondsia chinensis seed oilKey activeEffect: HighSoftens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.~1.1–1.7%
Sodium hyaluronateKey activeEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.6–1.4%
TriethylhexanoinKey activeEffect: HighHelps soften the upper layer of the skin~8.5–12.8%
Diisostearyl malateKey activeEffect: MediumHelps to soften the upper layer of the skin~22–33%
C20-40 alcoholsEffect: Low~2.2–3.4%
Lactic acidUnder-dosedEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~1.2–1.8%
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~0.5–1.2%
