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

It is a mineral sunscreen. In other words, it contains non-organic UV filters. It will probably not sting your eyes but might leave a white cast.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

Not advertised by the brand · 2 ingredients credited for this claim

Strong support

Hyaluronic acidEffect: LowOne 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~0.55–0.8%

Not advertised by the brand · No ingredient credited for this claim

Strong 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).

Moisturizing

Not advertised by the brand · 7 ingredients credited for this claim

Good 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, 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: helianthus annuus seed oil, hippophae rhamnoides oil.

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.65–0.95%

Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~5.5–6.7%

Hippophae rhamnoides oilKey active· EmollientEffect: HighA good emollient. Contains various ingredients including vitamins and fatty acids that could work in the skin to neutralize free radicals and minimize moisture loss - if enough of these compounds is able to penetrate the skin in an active form.~0.7–1.05%

Product summary

We assess that "Seed & Sprout - Tinted Zinc Sunscreen SPF50" can provide reliable sun protection based on the ingredient list. 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 product should also be hydrating enough to use without an additional moisturizer during the day. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.

Sunscreen filters

This sunscreen is a mineral sunscreen. It uses zinc oxide for sun protection. Zinc oxide almost never irritates the skin or stings eyes, but it can leave a white cast.

Irritation risk

There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of it to be medium. For a detailed overview of all potential irritants: click here
