Review

Results you may expect from using Guerlain L'Or 24K Gold Radiance and Hydrating Primer:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Guerlain L'Or 24K Gold Radiance and Hydrating Primer:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Little anti-wrinkle effect: Guerlain L'Or 24K Gold Radiance and Hydrating Primer has an anti-wrinkle rating of 0.1 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

How moisturizing is it?

Quite moisturizing: Guerlain L'Or 24K Gold Radiance and Hydrating Primer has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈7.5%) and Butylene Glycol (est. ≈3.0%).

Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

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

Anti-wrinkle efficacy

According to CreamScan analysis, Guerlain L'Or 24K Gold Radiance and Hydrating Primer has a minimal anti-wrinkle rating of 0.1 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈0.3%),
 or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
 
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.

Ingredients explained

Water
Est. %75
Function
Origin
The 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.
Glycerin
Est. %7.5
Function
Origin

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

Alcohol
Est. %5
Function
Origin
An effective antimicrobial ingredient that kills bacteria, fungi, and even some viruses. It is also an excellent solvent and astringent. Alcohol helps to create lighter and less viscous products. It can, however, be dehydrating and skin-sensitizing.
Butylene Glycol
Est. %3
Function
Origin
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.
Polysorbate 20
Est. %2.5
Function
Origin
A 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.
Phenoxyethanol
Est. %1
Function
Origin
The 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.
PEG-8
Est. %1
Function
Origin
A synthetic liquid that serves as a humectant. It also works as a solvent because of its ability to dissolve a wide range of ingredients.
Glyceryl Polymethacrylate
Est. %1
Function
Origin
A synthetic polymer that is typically used as a viscosity modifier. Its benefits include a light after-feel on the skin and soft film, which is why it is frequently used in serums. It can form transparent gels and suspend some oils and particulates.
Sorbitol
Est. %1
Function
Origin
A sweet-tasting alcohol derived from glucose. Aside from its sweet taste (for which it is used as a very common sweetener), Sorbitol is also very good at retaining water and is used in skincare as a humectant.
Ammonium Acryloyldimethyltaurate/VP Copolymer
Est. %0.3
Function
Origin
A polymeric ingredient that creates lightweight and refreshing gel textures. It also works as a viscosity controlling agent.
Fragrance
Est. %0.3
Function
Origin
Under trade secret law, manufacturers have the right not to disclose what exactly went into the fragrance and use the unspecific word Fragrance or Parfum instead. Many fragrances are highly allergenic.
Polyvinyl Alcohol
Est. %0.3
Function
Origin
A synthetic polymer that thickens water to form a gel and prevents other ingredients from separating.
Cellulose Gum
Est. %0.3
Function
Origin
A polymer that is derived from its namesake, cellulose, which is plant-based. It has many formula-helper benefits, including thickening and product stabilization.
Gold (CI 77480)
Est. %0.3
Function
Origin

A colorant used in skincare, typically processed into fine particles for uniform dispersion. Its luxurious hue enhances product aesthetics, while its role as a slip and surface modifier improves texture and application. Despite touted anti-aging benefits, definitive scientific evidence is lacking.

Butylphenyl Methylpropional
Est. %0.3
Function
Origin
A synthetic fragrance ingredient used to recreate the scent of lilies, this ingredient also features fresh, green, and powdery notes. Butylphenyl Methylpropional was recently labeled as Toxic to Reproduction in the EU and will be banned in 2022.
Linalool
Est. %0.3
Function
Origin
A fragrant, volatile compound naturally present in many essential oils. It has a pleasant scent and is often used in skincare products as a fragrance. People with sensitive skin should try to avoid it, or at least do a patch test before using it.
Citronellol
Est. %0.3
Function
Origin
A fragrant compound found naturally in many essential oils (mainly lemongrass). It can have a lemon or a rose scent. People with sensitive skin should try to avoid products with citronellol, or at least do a patch test before using it.
Alpha-Isomethyl Ionone
Est. %0.3
Function
Origin
A fragrance ingredient that is supplied as a pale, yellow liquid. The scent it emits is very clean and features notes of violet and orris. Alpha-isomethyl is also used as a flavoring agent in lip care products and even in some foods and drinks.
Benzyl Benzoate
Est. %0.3
Function
Origin
A fragrance ingredient with a fruity and woody scent. It is considered an allergen according to the International Fragrance Association (IFRA), which means that care must be taken when determining usage levels in skincare products.
Geraniol
Est. %0.3
Function
Origin
A fragrant, volatile, plant-based, liquid chemical that can be naturally found in many essential oils (specifically rose, palmarosa, citronella). It has a rose-like scent. It is a potential irritant and may cause an allergic reaction in some people.
Pentylene Glycol
Est. %0.3
Function
Origin
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.
Rosa Centifolia Flower Extract
Est. %0.3
Function
Origin
Derived from the Provence or cabbage rose, this extract contains a fragrant rose essential oil and astringent tannins.
Hydrolyzed Rice Protein
Est. %0.3
Function
Origin
A protein derived from rice bran with film-forming abilities. It can help increase moisturization in skin.
Ascorbic Acid
Est. %0.3
Function
Origin

Also known as vitamin C, this multi-benefit ingredient has proven anti-wrinkle, antioxidant, and anti-pigmentation efficacy. It degrades easily when exposed to air and light, so it requires proper packaging to maintain its stability.

Sodium Benzoate
Est. %0.3
Function
Origin
A preservative that usually works in combination with other preservatives. It has to be at low pH (<5.5) to be effective.
Potassium Sorbate
Est. %0.3
Function
Origin
A preservative widely used in food and personal care products, available from natural sources or synthetically produced. Potassium sorbate works by inhibiting the growth of yeasts, molds, and some bacteria.
BHT
Est. %0.3
Function
Origin
An antioxidant ingredient that naturally occurs in green algae and some bacteria or fungi but, for commercial use, is created synthetically. BHT is also used occasionally as a fragrance, where it presents a sweet, camphor-like odor.
