Product Summary
Based on the ingredient list, we assess that "belif - Dew Guard - Daily Mineral sun SPF 50 Hydrating Niacinamide 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).
It contains good moisturizing ingredients and can double as a hydrating day cream. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).
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 it to be high. For a detailed overview of all potential irritants: click here
You can see the detailed formula review with the breakdown of all actives in the product and the full ingredient list with estimated concentrations in the tables below.
Anti-aging
This product can help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation
Might be helpful in restoring skin barrier function and, when combined with zinc carbonate and malonic acid, reducing fine lines and wrinkles by stimulating elastin production. Also helps stabilize the product formulation
The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
Evens skin tone
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).

Moisturizing
What does the product description say?
Dew Guard , Daily Mineral sun SPF 50 Hydrating Niacinamide Sunscreen
Source: From product name
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

Sun protection
This product offers a good level of protection against both UVB and UVA rays.
