Key Benefits of Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+

 
These are the key benefits you can expect from using Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+:
 

🔵 Slight Moisturizing When Used Alone

According to CreamScan analysis, Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+ 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 Propanediol (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.

☀️☀️☀️ Very High Sun Protection for Prolonged Sun Exposure, All Skin Types, and High-risk Conditions

With an SPF of 50, Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+ provides very high sun protection, suitable for intense sun exposure in tropical climates, beach vacations, or high-altitude environments.

This level of SPF blocks 98% or more of UVB rays, offering the highest level of defense against sunburn. Broad-spectrum formulations also provide strong protection against UVA rays, which are responsible for skin aging, pigmentation, and DNA damage.

📌 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.

This level of SPF is ideal for all skin types, particularly fair, sensitive, or post-treatment skin (e.g., after laser or chemical procedures). It is also highly recommended for individuals at greater risk of skin cancer.

For extended outdoor activities or water exposure, choose a water-resistant formula and reapply every two hours for maximum 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: Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+

 
CreamScan AI identified a few things to consider before adding Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+ to your skincare routine:
 

⚠️ As a Standalone Moisturizer, It Has Relatively Low Moisturizing Potential

If you use Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+ 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.

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+ is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Centella Asiatica Extract, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Centella Asiatica Extract provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that Centella Asiatica Extract may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

Therefore, this ingredient does not generate 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, 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.

✅ Provides very high sun protection, ideal for intense sun exposure in tropical climates, high-altitude environments, and beach vacations, suitable for all skin types

Summary: Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+

 
Based on the ingredient list analysis, CreamScan AI suggests that Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+
, as a moisturizer, provides relatively light hydration on its own but can enhance the moisturizing efficacy of any skincare routine.

If you use Clearstem Skincare Youaresunshine Sheer Broad-Spectrum SPF 50+ as your primary moisturizer, please keep in mind that it provides only light hydration, which isn’t actually ideal for any skin type.
