Key Benefits of Round Lab 365 Derma Relief Sun Cream SPF50+ PA++++

 
These are the key benefits you can expect from using Round Lab 365 Derma Relief Sun Cream SPF50+ PA++++:
 

🔵 Lightweight Moisturizer Well-Suited for Oily Skin

According to CreamScan analysis, Round Lab 365 Derma Relief Sun Cream SPF50+ PA++++ is quite moisturizing, with a moisturizing rating of 4.4 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.5 out of 10 and a high humectancy of 7.2 out of 10, primarily due to the high content of Propanediol (est. ≈3.0%).

This humectant-rich product, when used alone as a moisturizer, is well-suited for oily skin, providing moderate hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It can also be a good option for people with normal skin who prefer lightweight moisturizers.

💧 A Humectant Enhancement for Any Skincare Routine

But it’s not limited to oily skin - such a humectant enhancement will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

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, Round Lab 365 Derma Relief Sun Cream SPF50+ 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: Round Lab 365 Derma Relief Sun Cream SPF50+ PA++++

 
CreamScan identified a few things to consider before adding Round Lab 365 Derma Relief Sun Cream SPF50+ PA++++ to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Round Lab 365 Derma Relief Sun Cream SPF50+ PA++++ 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.
