Key Benefits of Isntree Hyaluronic Acid Airy Sun Stick SPF50+ PA++++

 
These are the key benefits you can expect from using Isntree Hyaluronic Acid Airy Sun Stick SPF50+ PA++++:
 

Lightweight Moisturizer Suitable for Oily Skin

According to CreamScan analysis, Isntree Hyaluronic Acid Airy Sun Stick SPF50+ PA++++ is lightly moisturizing, with a moisturizing rating of 2.4 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 0.3 out of 10 and a moderate humectancy of 4.5 out of 10, primarily due to Butylene Glycol (est. ≈0.3%), Niacinamide (est. ≈0.3%) and Mesembryanthemum Crystallinum Extract (est. ≈0.3%).

This product, when used alone as a moisturizer, can provide light humectant hydration in a fast-absorbing formula with a minimal amount of occlusive ingredients. This could work for people with oily skin who need a basic level of hydration.

A Humectant Add-on for Any Skincare Routine

But it’s not limited to oily skin - since it contains a moderate amount of humectants, such a humectant add-on will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

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

Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Isntree Hyaluronic Acid Airy Sun Stick SPF50+ PA++++ has a slight anti-wrinkle rating of 0.4 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈0.3%), 
 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 Airy Sun Stick SPF50+ PA++++ also contains Adenosine, an ingredient often 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, 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 Airy Sun Stick SPF50+ PA++++ is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈0.3%), Pinus Pinaster Bark Extract (est. ≈0.3%), Bambusa Vulgaris Water (est. ≈0.3%), and others.

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 Airy Sun Stick 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 AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Ingredients explained

Water
Est. %60
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Polyethylene
Est. %9
Function
Origin
PolyethyleneCommonly used in dense plastic packaging, its primary function in skincare is as a film-forming agent, which protects the product from being easily rinsed away by water or sweat. It also controls viscosity by increasing the thickness of oily products.
Propylheptyl Caprylate
Est. %6
Function
Origin
Propylheptyl Caprylate
C12-15 Alkyl Benzoate
Est. %4
Function
Origin
C12-15 Alkyl BenzoateA synthetic emollient ester. It works to improve the appearance of the skin by filling in the microcracks on the surface, thereby making the skin appear softer and smoother. It imparts a lightweight, velvety feel.

Est. %3
Function
Origin
HomosalateA synthetic chemical UV filter that protects against harmful UVB radiation.
Silica
Est. %2.5
Function

Octinoxate
Est. %2
Function
Origin
OctinoxateA chemical sunscreen also known as ethylhexyl methoxycinnamate. It protects against UVB, which causes the skin to burn and tan and can lead to certain types of skin cancers. For broad-spectrum protection claims, octinoxate should be paired with a UVA sunscreen.
