Review

Results you may expect from using Isntree Hyaluronic Acid Airy Sun Stick SPF50+ PA++++:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Isntree Hyaluronic Acid Airy Sun Stick SPF50+ PA++++:

  • Light moisturizing. It has a moisturizing rating of 2.4 out of 10.
  • Little anti-wrinkle effect: Isntree Hyaluronic Acid Airy Sun Stick SPF50+ PA++++ has an anti-wrinkle rating of 0.4 out of 10, so you may expect a positive, although insignificant, 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?

Lightly moisturizing: Isntree Hyaluronic Acid Airy Sun Stick SPF50+ PA++++ has 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%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Isntree Hyaluronic Acid Airy Sun Stick SPF50+ PA++++ has a minimal 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.
 
Among others, Isntree Hyaluronic Acid Airy Sun Stick SPF50+ 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 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.

Sun protection

Isntree Hyaluronic Acid Airy Sun Stick SPF50+ 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.

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 CaprylateDescription is coming soon
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.
Homosalate
Est. %3
Function
Origin
HomosalateA synthetic chemical UV filter that protects against harmful UVB radiation.
Silica
Est. %2.5
Function
Origin
SilicaA widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
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.
Neopentyl Glycol Diheptanoate
Est. %1.5
Function
Origin
Neopentyl Glycol DiheptanoateAn emollient ester with an exceptionally lightweight feel. It absorbs quickly and produces a silky feel with excellent spreadability. It also serves as an excellent solvent and is commonly used to suspend sunscreen actives.

Function
Origin
Vinyl Dimethicone/Methicone Silsesquioxane CrosspolymerDescription is coming soon
Octisalate
Est. %1
Function
Origin

Butylene Glycol
Est. %0.3
Function
Origin
Butylene GlycolA clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.
Synthetic Fluorphlogopite
Est. %0.3
Function
Origin
Synthetic FluorphlogopiteAlso known as synthetic mica, this ingredient’s best property is its ability to form thin, sheet-like crystals. This gives products (mostly makeup) great slip.
