Key Benefits of Laura Mercier Flawless Fusion Ultra Longwear Concealer

 
These are the key benefits you can expect from using Laura Mercier Flawless Fusion Ultra Longwear Concealer:
 

🔵 Lightweight Moisturizer Well-Suited for Oily Skin

According to CreamScan analysis, Laura Mercier Flawless Fusion Ultra Longwear Concealer is quite moisturizing, with a moisturizing rating of 4.6 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.5 out of 10 and a high humectancy of 7.7 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%) and Butylene Glycol (est. ≈2.5%).

This humectant-rich product, when used alone as a moisturizer, is well-suited for oily skin, providing moderate hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It can also be a good option for people with normal skin who prefer lightweight moisturizers.

💧 A Humectant Enhancement for Any Skincare Routine

But it’s not limited to oily skin - such a humectant enhancement 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.

📌 Please note that this is not a complete list of benefits. We are in the process of enhancing our model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Laura Mercier Flawless Fusion Ultra Longwear Concealer

 
CreamScan identified a few things to consider before adding Laura Mercier Flawless Fusion Ultra Longwear Concealer to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Laura Mercier Flawless Fusion Ultra Longwear Concealer is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Ascorbyl Glucoside, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Ascorbyl Glucoside provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that Ascorbyl Glucoside may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

Therefore, this ingredient does not generate 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.

Cyclopentasiloxane
Est. %9
Function
Origin
CyclopentasiloxaneA lightweight, fast-spreading emollient that leaves a very soft and silky after-feel on the skin. Supplied as a clear and colorless liquid, cyclopentasiloxane is often used as a solvent to dissolve other silicones in.

Butylene Glycol
Est. %2.5
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.

Heptyl Undecylenate

Function
Origin
Heptyl Undecylenate
Phenyl Trimethicone
Est. %1.5
Function

Trimethylsiloxysilicate
Est. %1.3
Function
Origin
TrimethylsiloxysilicateAn occlusive moisturizing and emollient silicone resin that smoothes and softens the appearance of the skin. It also protects a product from rinsing away too easily with water, sweat, or friction.
Neopentyl Glycol Diheptanoate
Est. %1
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.
Bis-PEG/PPG-14/14 Dimethicone
Est. %0.3
Function
Origin
Bis-PEG/PPG-14/14 Dimethicone
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.
Quaternium-90 Bentonite
Est. %0.3
Function
Origin
Quaternium-90 Bentonite
Acrylates/C12-22 Alkyl Methacrylate Copolymer

Boron Nitride
Est. %0.3
Function
Origin

Lecithin
Est. %0.3
Function
Origin
LecithinA humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.
Pentylene Glycol
Est. %0.3
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.

Dimethicone/Vinyl Dimethicone Crosspolymer
Est. %0.3
Function
Origin
Dimethicone/Vinyl Dimethicone CrosspolymerThis ingredient can refer to several kinds of dimethicone crosspolymers. Like other silicones, it makes products feel slippery and non-greasy but can also increase the thickness or improve the water-resistance of a formula.
Ascorbyl Glucoside
Est. %0.3
Function
Origin
Ascorbyl GlucosideA derivative of vitamin C. It is more stable and less irritating than ascorbic acid. There are unfortunately no clinical studies on ascorbyl glucoside’s anti-pigment or anti-acne efficacy alone.

Origin
Propylene CarbonateA derivative of propylene glycol that is used most frequently as a solvent. Additionally, propylene carbonate serves as a viscosity controlling agent reducing the thickness of the products it is added to.
Aluminum Dimyristate
Est. %0.3
Function
Origin
Aluminum Dimyristate
Triethoxycaprylylsilane
Est. %0.3
Function
Origin
