“Belif's dew guard glow boost serum spf 40 is a three-in-one formula, delivering lightweight hydration, sun protection, and sun-kissed illumination.This korean sunscreen gives your skin a golden glow and creates a 촉촉 (chok-chok) effect — the look and feel of hydrated, bouncy, and plump skin.”
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, hyaluronic acid.
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, isododecane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
Evens skin toneNot advertised by the brand · 2 ingredients credited for this claimStrong support
This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).

Product summary
We believe that "belif - Dew Guard Glow Boost Serum SPF 40" 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).
It contains good moisturizing ingredients and can double as a hydrating day cream. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.
Sunscreen filters
This sunscreen uses a mixture of both mineral and organic (so-called "chemical") UV filters. Here are the organic filters this product uses: avobenzone, octisalate, homosalate and octocrylene. As for the mineral filters, this sunscreen uses titanium dioxide.
Irritation risk
There are quite a few common irritants in this product, including ingredients without particular skin benefits. We would not recommend it for sensitive skin. We assess the overall irritancy of this sunscreen to be high. For a detailed overview of all potential irritants: click here
