Review

Results you may expect from using COSRX Ultra-Light Invisible Sunscreen SPF 50 PA++++:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using COSRX Ultra-Light Invisible Sunscreen SPF 50 PA++++:

  • Moderate moisturizing. It has a moisturizing rating of 4.7 out of 10.
  • Some anti-wrinkle efficacy: COSRX Ultra-Light Invisible Sunscreen SPF 50 PA++++ has an anti-wrinkle rating of 3.0 out of 10 so you may expect some, although limited, effect on wrinkles.
  • 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: COSRX Ultra-Light Invisible Sunscreen SPF 50 PA++++ has a moisturizing rating of 4.7 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.2 out of 10 and a very high humectancy of 9.2 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, COSRX Ultra-Light Invisible Sunscreen SPF 50 PA++++ has a slight anti-wrinkle rating of 3.0 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈2.0%), 
 one of the most effective and well-researched anti-wrinkle ingredients.
 
Among others, COSRX Ultra-Light Invisible 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.

Sun protection

COSRX Ultra-Light Invisible 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.
