Does Round Lab Birch Juice Moisturizing Sun Cushion SPF 50+ PA++++ work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Round Lab Birch Juice Moisturizing Sun Cushion SPF 50+ PA++++:

  • Moderate moisturizing. It has a moisturizing rating of 5.3 out of 10.
  • Little anti-wrinkle effect: Round Lab Birch Juice Moisturizing Sun Cushion SPF 50+ PA++++ has an anti-wrinkle rating of 0.1 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Very high sun protection for prolonged sun exposure, such as spending the day at the beach, hiking, or outdoor sports.

Suitable moisturizer for normal skin with a relatively lightweight texture

According to CreamScan analysis, Round Lab Birch Juice Moisturizing Sun Cushion SPF 50+ PA++++ is quite moisturizing, with a moisturizing rating of 5.3 out of 10.

Is it more humectant or occlusive? This product has relatively comparable levels of humectancy and occlusivity: a moderate humectancy of 5.9 out of 10 and a moderate occlusivity of 4.7 out of 10, primarily due to the high content of Caprylyl Methicone (est. ≈6.0%) and Butylene Glycol Dicaprylate/Dicaprate (est. ≈2.5%).

This type of moisturizer can work well for people with normal skin. It combines a moderate amount of humectants and occlusive ingredients to provide dual-action moisturizing for normal skin.

However, it contains a moderate level of humectants, and people with normal skin would definitely benefit from adding more humectants to their moisturizing routine beyond what this product offers. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.

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

Little anti-wrinkle efficacy

According to CreamScan analysis, Round Lab Birch Juice Moisturizing Sun Cushion SPF 50+ PA++++ 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 ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
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.

Very high sun protection for prolonged sun exposure, all skin types, and high-risk conditions

With an SPF of 50, Round Lab Birch Juice Moisturizing Sun Cushion 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.
