What the product description says
“It not only leaves skin looking flawless; it has clinically-proven skin benefits, offering broad spectrum defence against UVA and UVB rays to prevent sun damage and premature ageing.”
Source: Feelunique

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).

Anti-oxidation

This product contains antioxidants (ethylbisiminomethylguaiacol manganese chloride) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

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: anhydroxylitol, 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, cyclopentasiloxane.

AnhydroxylitolKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and repair the skin barrir function~0.35–0.65%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~1.7–2.1%

Product summary

Based on the ingredient list, we assess that "ARK Skincare - Skin Protector SPF 30 Primer" 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).

This sunscreen 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).

Sunscreen filters

This is a so-called "chemical" sunscreen. It means that it uses organic UV filters. They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin. These are the sun protection ingredients in this sunscreen: oxybenzone 3.40% - 4.10%, avobenzone 3.00% - 3.70%, octinoxate 4.30% - 5.30% and octocrylene 6.10% - 7.50%.

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 product to be high. For a detailed overview of all potential irritants: click here
