Does No7 Laboratories Firming Booster Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using No7 Laboratories Firming Booster Serum:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.8 out of 10.

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

According to CreamScan analysis, No7 Laboratories Firming Booster Serum is quite moisturizing, with a moisturizing rating of 5.8 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 maximum humectancy of 10 out of 10, primarily due to the high content of Butylene Glycol (est. ≈6.0%) and Glycerin (est. ≈4.0%).

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.

Questionable anti-wrinkle efficacy

According to CreamScan analysis, No7 Laboratories Firming Booster Serum has a zero anti-wrinkle rating.

It contains Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7, 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 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.

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.
Butylene Glycol
Est. %6
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.

Glycerin
Est. %4
Function
Origin
Glycerin

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

Dimethicone
Est. %3
Function
Origin
DimethiconeThe most common silicone in skincare. It forms a silky, smooth film on the skin’s surface and can help to prevent water loss. It also aids in wound healing and can treat and soften scars. Dimethicone is considered to be very safe for use.
Aluminum Starch Octenylsuccinate
Est. %2
Function
Origin
Aluminum Starch OctenylsuccinateAn absorbent that takes in oils from the skin to reduce the oily sheen. It can also absorb oils from the skincare product itself, resulting in a softer, less greasy product, normally with better spreadability and less tack.
Isononyl Isononanoate
Est. %1.5
Function
Origin
Isononyl IsononanoateAn ester of a branched fatty acid with a branched fatty alcohol. It is an easily spreadable emollient that has a silky, dry, non-greasy feel on the skin.
Ammonium Acryloyldimethyltaurate/VP Copolymer
Est. %1.3
Function
Origin
Ammonium Acryloyldimethyltaurate/VP CopolymerA polymeric ingredient that creates lightweight and refreshing gel textures. It also works as a viscosity controlling agent.
Pentylene Glycol
Est. %1
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 Crosspolymer
Est. %0.3
Function
Origin
Dimethicone CrosspolymerA group of ingredients that are typically added to skincare products to adjust the formula. Dimethicone Crosspolymers stabilize a formula, regulate its thickness and consistency and give the product a velvety feel.
Hibiscus Abelmoschus Extract
Est. %0.3
Function
Origin
Hibiscus Abelmoschus ExtractA rarely used fragrant extract from Musk mallow that has a heavy, sweet, and musky aroma.
Sodium Hyaluronate
Est. %0.3
Function
Origin
Sodium Hyaluronate

A sodium salt of famous hyaluronic acid. A potent humectant that hydrates the skin, supports collagen function, and fills out small wrinkles. Sodium hyaluronate also offers soothing and antioxidant properties.

Phenoxyethanol
Est. %0.3
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Xanthan Gum
Est. %0.3
Function
Origin

Hydrolyzed Hyaluronic Acid
Est. %0.3
Function
Origin
Hydrolyzed Hyaluronic AcidA smaller-molecule version of the regular hyaluronic acid. It is a powerful humectant that absorbs into the skin and offers moisturizing, smoothing, and anti-wrinkle effects. It is also slightly anti-inflammatory and displays subtle antioxidant properties.
Sorbitan Laurate
Est. %0.3
Function
Origin
Sorbitan LaurateSorbitan laurate is a sugar-based emulsifier similar to sucrose palmitate. It keeps oil broken into small droplets throughout water because of its chemical shape and nature (this is how most oil-in-water emulsifiers work by the way). These kinds of emulsifiers are mild enough to even be used in food preparations.
Polysorbate 20
Est. %0.3
Function
Origin
Polysorbate 20A viscous, amber-colored liquid that functions as a solubilizer to disperse small amounts of oil into a large water phase. Polysorbate 20 is frequently used to solubilize fragrance oils into water-based emulsions.
