MoisturizingSide benefit the brand mentions · Chondrus crispus extract, Glycosyl trehalose + 11 moreWorks
“The Sekkisei brightening skin care series uses a Japanese herbal extract that gently moisturizes and protects skin while brightening the complexion.”
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 collagen.
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: chondrus crispus extract, hydrolyzed collagen.

Product summary
Based on the ingredients included, we believe that "Kose - DECORTE Sun Shelter Multi Protection SPF 50 PA++++" can offer 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).
It also works as a moisturizer, so you do not have to use an additional hydrating product. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.

They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin.
