What the product description says
“Gradual Tan Moisture Miracle Watermelon 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, hydrolyzed hyaluronic acid.

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: cocos nucifera oil, isopropyl myristate.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: paraffinum liquidum

Paraffinum liquidumHeroEffect: HighMineral oil. One of the most effective and well studied occlusive and emollient moisturizing ingredients. Helps reduce moisture loss in skin and repair skin barrier function~6.4–7.8%
Isopropyl myristateKey activeEffect: HighAn emollient that helps soften the skin. Could be comedogenic~2.4–3%
Cetearyl alcoholKey activeEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~1.7–2.1%
GlycerinKey activeEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~1.3–1.6%
Cetyl alcoholKey activeEffect: MediumA non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together~0.55–0.85%
Cocos nucifera oilKey activeEffect: HighAn emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic~0.5–0.7%
Hydrolyzed hyaluronic acidKey activeEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin~0.25–0.4%
Glyceryl stearateEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~1.5–1.9%
Caprylyl glycolEffect: LowHelps preserve products and creates a nice product texture~0.4–0.65%
Lactobacillus/arundinaria gigantea ferment filtrateEffect: LowFermented bamboo. It is mainly used to improve the product texture~0.4–0.65%
Lactic acidUnder-dosedAn 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)~0.1–0.15%
