Review

Results you may expect from using Round Lab Birch Moisturizing Sunscreen SPF 50+ PA++++:

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

  • Moderate moisturizing. It has a moisturizing rating of 5.3 out of 10.
  • Some anti-wrinkle efficacy: Round Lab Birch Moisturizing Sunscreen SPF 50+ PA++++ has an anti-wrinkle rating of 3.1 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Antioxidant protection.
  • Very high sun protection for prolonged sun exposure, such as spending the day at the beach, hiking, or outdoor sports.

How moisturizing is it?

Quite moisturizing: Round Lab Birch Moisturizing Sunscreen SPF 50+ PA++++ has a moisturizing rating of 5.3 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.6 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Propanediol (est. ≈6.0%) and Niacinamide (est. ≈2.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Round Lab Birch Moisturizing Sunscreen SPF 50+ PA++++ has a slight anti-wrinkle rating of 3.1 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

  • Niacinamide (est. ≈2.0%),
     one of the most effective and well-researched anti-wrinkle ingredients.
  • Ascorbic Acid (est. ≈0.3%),
     or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
Among others, Round Lab Birch Moisturizing Sunscreen SPF 50+ PA++++ also contains Adenosine, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Adenosine provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to 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, could deliver additional anti-wrinkle efficacy through its moisturizing action.
 

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

Antioxidant benefits

We estimate that Round Lab Birch Moisturizing Sunscreen SPF 50+ PA++++ is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈2.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Sun protection

Round Lab Birch Moisturizing Sunscreen SPF 50+ PA++++ has an SPF of 50 and provides very high sun protection. This level of protection is ideal for activities involving intense or prolonged sun exposure, such as spending the day at the beach, hiking, or outdoor sports. It is particularly recommended for individuals with fair skin, those at high risk of skin cancer, or in environments with intense sun exposure. Remember to apply sunscreen generously and reapply every two hours or after swimming or sweating to maintain effectiveness.
