Key Benefits of Kate Somerville Daily Deflector Mineral Face Sunscreen SPF 40 | PA++++

 
These are the key benefits you can expect from using Kate Somerville Daily Deflector Mineral Face Sunscreen SPF 40 | PA++++:
 

Slight Moisturizing When Used Alone

According to CreamScan analysis, Kate Somerville Daily Deflector Mineral Face Sunscreen SPF 40 | PA++++ is slightly moisturizing, with a moisturizing rating of 1.8 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 0.3 out of 10 and a moderate humectancy of 3.3 out of 10, primarily due to the high content of Glycerin (est. ≈3.0%).

This type of product provides relatively light moisturizing on its own but can contribute to overall moisturizing efficacy when used as part of a skincare routine, alongside another moisturizer.

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

Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Kate Somerville Daily Deflector Mineral Face Sunscreen SPF 40 | PA++++ has a slight anti-wrinkle rating of 0.4 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ectoin (est. ≈0.3%), 
 an amino acid-derived ingredient with moderate but proven anti-wrinkle efficacy.  A single clinical study involving 104 participants (Heinrich et al.) confirmed that a cream containing 2% ectoin reduced the average wrinkle width by 7% after 4 weeks of use, compared to the same formulation without ectoin (vehicle).
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.
 

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

High sun protection for extended outdoor activities and exposure

With an SPF of 40, Kate Somerville Daily Deflector Mineral Face Sunscreen SPF 40 | PA++++ provides high sun protection, making it ideal for prolonged outdoor activities such as hiking, gardening, sports, or spending time at the beach.

This level of SPF blocks up to 98% of UVB rays, significantly reducing the risk of sunburn. When formulated as broad-spectrum, it also protects against UVA rays, which penetrate deeper into the skin and contribute to premature aging, hyperpigmentation, and long-term damage.

This level of SPF is recommended for most skin types, including those with moderate sun sensitivity. For individuals with fair or very sensitive skin, or under intense sun exposure, a higher SPF of 50+ is advised.

For optimal protection, choose products labeled broad-spectrum to ensure defense against both UVA rays, which contribute to skin aging and pigmentation, and UVB rays that cause sunburn.

It's important to apply sunscreen generously and reapply every two hours or after swimming or sweating to maintain effectiveness.

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Kate Somerville Daily Deflector Mineral Face Sunscreen SPF 40 | PA++++

 
CreamScan AI identified a few things to consider before adding Kate Somerville Daily Deflector Mineral Face Sunscreen SPF 40 | PA++++ to your skincare routine:
 

As a Standalone Moisturizer, It Has Relatively Low Moisturizing Potential

If you use Kate Somerville Daily Deflector Mineral Face Sunscreen SPF 40 | PA++++ for moisturizing purposes, please keep in mind that it provides relatively light moisturizing on its own, and, more importantly, it’s not optimal for any skin type.

On one hand, it has low occlusivity, which suits oily and combination skin. On the other hand, it has a low estimated concentration of humectants, which are essential for effective moisturizing of all skin types, including oily skin.

Therefore, if used as a standalone moisturizer, this product should be paired with a humectant-rich moisturizer for optimal skin hydration.

  • Provides slight anti-wrinkle efficacy
