This product uses a single UV filter (zinc oxide) in a relatively low concentration and might not be able to provide a reliable sun protection.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

What the product description says
“Thanks to natural ingredients like Sodium Hyaluronate, this sunscreen doubles as a daily moisturizer, leaving your skin comfortably hydrated with a shine-free finish.”
Source: SmallFlower

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, isomalt.

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: butyrospermum parkii butter, squalane.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: avena sativa kernel extract

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.25–0.45%
SqualaneKey active· Emollient, OcclusiveEffect: HighAn oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.~1.1–1.4%
Butyrospermum parkii butterKey active· Emollient, OcclusiveEffect: HighA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~1.1–1.3%
IsomaltKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~0.5–0.8%
Avena sativa kernel extractHero· EmollientEffect: HighAn effective moisturizing and skin barrier repair ingredient. Helps calm down inflammation and has some anti-oxidant properties~25–31%
Theobroma grandiflorum seed butterKey activeEffect: HighHelps soften the upper layer of the skin and might as well help to attract moisture to its upper layer~0.95–1.15%

Calcium gluconate· HumectantEffect: LowHelps attract water to the upper layer of the skin and helps to improve appearance of the product~0.2–0.35%
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)~0.65–1%
GluconolactoneUnder-dosedEffect: HighA 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~0.25–0.5%
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~0.2–0.4%

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - butyrospermum parkii butter - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
