MoisturizingSide benefit · Cyclopentasiloxane, Alcaligenes polysaccharides + 3 moreWorks
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:
alcaligenes polysaccharides, butylene glycol.
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: squalane, alcaligenes polysaccharides.

Product summary
We believe that "Santan - Sumikko Gurashi Sunscreen Otomarikai SPF 30 PA++" can provide reliable sun protection based on the ingredients listed. 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 sunscreen should also be hydrating enough to use without an additional moisturizer during the day. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.
