MoisturizingNot advertised by the brand · 5 ingredients credited for this claimGood support
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: dimethicone, behenyl alcohol.

Product summary
The ingredient list suggests that "Kose - Sekkisei Miyabi UV Defense AG Mild SPF30 PA +++" can provide reliable sun protection. It can protect from both UVA and UVB rays. This is great news because 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).
This product should also be hydrating enough to use without an additional moisturizer during the day. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).
