MoisturizingNot advertised by the brand · Helianthus annuus seed oil, Glycerin + 9 moreGood evidence
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.
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: helianthus annuus seed oil, cetyl alcohol.

Product summary
Based on the ingredient list, we assess that "Kinfield - Sunglow SPF 30 Luminizing Sunscreen" can provide reliable sun protection. We love that it can protect from both UVA and UVB rays (not all sunscreens with SPF ratings give UVA protection. UVA rays do not cause sunburn, but still damage our skin and lead to early aging).
Its formula is also hydrating, so you might not need an additional moistruizer during the day. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.
