Does Glossier Stretch Fluid Foundation Medium Tan 4 work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Glossier Stretch Fluid Foundation Medium Tan 4:

  • Moderate moisturizing. It has a moisturizing rating of 4.4 out of 10.
  • Little anti-wrinkle effect: Glossier Stretch Fluid Foundation Medium Tan 4 has an anti-wrinkle rating of 0.4 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

Lightweight moisturizer well-suited for oily to normal skin

According to CreamScan analysis, Glossier Stretch Fluid Foundation Medium Tan 4 is quite moisturizing, with a moisturizing rating of 4.4 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.3 out of 10 and a high humectancy of 6.6 out of 10, primarily due to the high content of Propanediol (est. ≈2.0%).

This type of moisturizer is well-suited for people with oily skin who want significant hydration in a relatively lightweight, non-greasy formula. It combines a substantial amount of humectants with a limited amount of occlusive to enhance moisturizing efficacy without feeling too heavy.

This product may also be an option for people with normal skin who prefer fast-absorbing textures, as it balances moderate moisturizing potential with a relatively lightweight texture.

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

Little anti-wrinkle efficacy

According to CreamScan analysis, Glossier Stretch Fluid Foundation Medium Tan 4 has a minimal anti-wrinkle rating of 0.4 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ectoin (est. ≈0.3%), 
 an amino acid-derived ingredient with moderate but proven anti-wrinkle efficacy.  A single clinical study involving 104 participants (Heinrich et al.) confirmed that a cream containing 2% ectoin reduced the average wrinkle width by 7% after 4 weeks of use, compared to the same formulation without ectoin (vehicle).
 
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.

Ingredients explained

Water
Est. %75
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.
C9-12 Alkane
Est. %6
Function
Origin
C9-12 Alkane
Squalane
Est. %4
Function
Origin
SqualaneAn occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
Coco-Caprylate/Caprate
Est. %3
Function
Origin
Coco-Caprylate/CaprateA naturally-derived emollient ester. It is a blend of caprylates and caprates and, relative to other emollients, is lightweight and dry on the skin. As a result, coco-caprylate/caprate serves as a natural alternative to volatile silicones.
Propanediol
Est. %2
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Glycerin
Est. %1.5
Function
Origin
Glycerin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Pentylene Glycol
Est. %1.3
Function
Origin
Pentylene Glycol

A naturally or synthetically derived preservative that exhibits effective antifungal and antibacterial traits. It also acts as a booster for more traditional preservatives. Pentylene glycol can also serve as a moisturizing humectant and solvent.

Sorbitan Isostearate
Est. %1
Function
Origin
Sorbitan IsostearateA mild yet powerful emulsifier primarily utilized to produce water-in-oil emulsions. It helps to create a particularly rich and substantial emulsion.
Polyglyceryl-3 Polyricinoleate
Est. %0.3
Function
Origin
Polyglyceryl-3 Polyricinoleate
Tribehenin
Est. %0.3

Ethyl Oleate
Est. %0.3
Function
Origin

Butylene Glycol
Est. %0.3
Function
Origin
Butylene Glycol

A 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.

Disteardimonium Hectorite
Est. %0.3
Function
Origin
Disteardimonium HectoriteA clay ingredient that functions primarily as a viscosity controlling agent that thickens all types of formulas. Disteardimonium hectorite imparts a smooth, velvety feel, making it a luxurious addition to any formula.
Ectoin
Est. %0.3
Function
Origin
Ectoin

An amino acid-derived ingredient with average, yet proven by one study, anti-wrinkle efficacy.

Silica
Est. %0.3
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.
Rosa Canina Fruit Extract
Est. %0.3
Function
Origin
Rosa Canina Fruit ExtractAn extract from the fruits of the Rosa canina, better known as rosehip. It contains carotenoids, which give it its bright, orange-red color, as well as high amounts of antioxidant vitamin C, flavonoids, tannins, and organic acids.
