  • Moderate moisturizing. It has a moisturizing rating of 4.8 out of 10.

How moisturizing is it?

Quite moisturizing: Zo Skin Health Sunscreen + Prime Broad-Spectrum SPF 30 has a moisturizing rating of 4.8 out of 10.

Is it more humectant or occlusive? Significantly more occlusive. It has a low Humectancy of 1.5 out of 10 and a very high Occlusivity of 8.1 out of 10, primarily due to the high content of Dimethicone (est. ≈11.0%) and Phenyl Trimethicone (est. ≈3.0%).

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Anti-wrinkle efficacy

According to CreamScan analysis, Zo Skin Health Sunscreen + Prime Broad-Spectrum SPF 30 has a minimal anti-wrinkle rating of 0.1 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈0.3%),
 or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
 
Among others, Zo Skin Health Sunscreen + Prime Broad-Spectrum SPF 30 also contains contains Centella Asiatica Leaf Extract and Retinyl Palmitate, two ingredients marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do not contribute to the anti-wrinkle rating.
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, could deliver additional anti-wrinkle efficacy through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Antioxidant benefits

We estimate that Zo Skin Health Sunscreen + Prime Broad-Spectrum SPF 30 is rich (> 3%) in antioxidants, specifically Glycyrrhiza Uralensis (Licorice) Root Extract (est. ≈1.5%), Centella Asiatica Leaf Extract (est. ≈0.3%), Glycine Soja (Soybean) Seed Extract (est. ≈0.3%), and others.

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Sun protection

Zo Skin Health Sunscreen + Prime Broad-Spectrum SPF 30 has an SPF of 30 and provides high sun protection. This level of protection is ideal for activities such as spending time at the beach, outdoor sports, or other activities involving prolonged sun exposure. It's important to apply sunscreen generously and reapply every two hours or after swimming or sweating to maintain effectiveness.
