Does Isntree Hyaluronic Acid Perfect Sun Block SPF 50 PA++++ work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Isntree Hyaluronic Acid Perfect Sun Block SPF 50 PA++++:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.3 out of 10.
  • Some anti-wrinkle efficacy: Isntree Hyaluronic Acid Perfect Sun Block SPF 50 PA++++ has an anti-wrinkle rating of 3.0 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.

Lightweight moisturizer ideal for oily skin and a humectant boost for any skincare routine

According to CreamScan analysis, Isntree Hyaluronic Acid Perfect Sun Block SPF 50 PA++++ is quite moisturizing, with 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. ≈4.0%), Butylene Glycol (est. ≈3.0%) and Niacinamide (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients. It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

Such a humectant boost 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.

Some anti-wrinkle efficacy

According to CreamScan analysis, Isntree Hyaluronic Acid Perfect Sun Block 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. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, Isntree Hyaluronic Acid Perfect Sun Block SPF 50 PA++++ also contains contains Centella Asiatica Extract and Adenosine, two ingredients often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do 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, 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.

Rich in skin-protecting antioxidants

We estimate that Isntree Hyaluronic Acid Perfect Sun Block 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.

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

With an SPF of 50, Isntree Hyaluronic Acid Perfect Sun Block 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.
