Key Benefits of Cathy Doll Ultra Light Sun Fluid SPF 50 PA++++

 
These are the key benefits you can expect from using Cathy Doll Ultra Light Sun Fluid SPF 50 PA++++:
 

🔵 Slight Moisturizing When Used Alone

According to CreamScan analysis, Cathy Doll Ultra Light Sun Fluid SPF 50 PA++++ is slightly moisturizing, with a moisturizing rating of 0.8 out of 10.

Is it more humectant or occlusive? This product has relatively comparable levels of Humectancy and Occlusivity: a low Humectancy of 1.2 out of 10 and a low Occlusivity of 0.3 out of 10.

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, Cathy Doll Ultra Light Sun Fluid SPF 50 PA++++ 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 model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Cathy Doll Ultra Light Sun Fluid SPF 50 PA++++

 
CreamScan identified a few things to consider before adding Cathy Doll Ultra Light Sun Fluid SPF 50 PA++++ to your skincare routine:
 

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

If you use Cathy Doll Ultra Light Sun Fluid SPF 50 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.

Pros & Cons of Cathy Doll Ultra Light Sun Fluid SPF 50 PA++++

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