Review

Results you may expect from using Guinot Time Logic Age Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Guinot Time Logic Age Serum:

  • Moderate moisturizing. It has a moisturizing rating of 5.4 out of 10.
  • Little anti-wrinkle effect: Guinot Time Logic Age Serum has an anti-wrinkle rating of 0.5 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

How moisturizing is it?

Quite moisturizing: Guinot Time Logic Age Serum has a moisturizing rating of 5.4 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.9 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Propylene Glycol (est. ≈10.8%) and Glycerin (est. ≈5.9%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Guinot Time Logic Age Serum has a minimal anti-wrinkle rating of 0.5 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:
    • Niacinamide (est. ≈0.3%),
       one of the most effective and well-researched anti-wrinkle ingredients.
    • Ascorbic Acid (est. ≈0.3%),
       or Vitamin C, a popular anti-wrinkle ingredient, yet with average efficacy confirmed by only one study.
Among others, Guinot Time Logic Age Serum also contains some ingredients marketed as effective in reducing wrinkles, specifically Sodium Ascorbyl Phosphate, Retinyl Acetate, and Folic Acid. 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 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.

Ingredients explained

Cyclopentasiloxane
Est. %30
Function
Origin
A 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.
Water
Est. %21.6
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.
Propylene Glycol
Est. %10.8
Function
Origin
A clear, thick, odorless liquid of synthetic origin. Its main function is to stabilize cosmetic products exposed to varying temperatures. It is also a moderately strong humectant with similar properties to glycerin.
Glycerin
Est. %5.9
Function
Origin

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

Cyclohexasiloxane
Est. %3.9
Function
Origin
A clear silicone fluid with very low viscosity that is commonly used as a solvent and emollient. It has excellent spreadability, rubs in quickly, and leaves a silky smooth after-feel on the skin.
Methyl Methacrylate Crosspolymer
Est. %2.9
Function
Origin
A synthetic ingredient that is used for bulking, film-forming, and controlling viscosity. It can absorb large amounts of water and oil and creates a network for other ingredients to live in.
Alcohol Denat.
Est. %2
Function
Origin

Denatured alcohol is ethanol that contains additives that make it unsafe to consume. It is mainly used as a solvent and an antimicrobial agent. A major drawback to alcohol denat. is that it dries out the skin.

Dimethicone
Est. %1.5
Function
Origin
The 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.
PEG/PPG-18/18 Dimethicone
Est. %1
Function
Origin
A silicone-based emulsifier that has the ability to create non-sticky and non-greasy formulas.
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.

Est. %0.3
Function
Origin
Description is coming soon
Sodium Chloride
Est. %0.3
Function
Origin
You’re definitely familiar with sodium chloride, even if you don’t think you are. It’s table salt! Salt works well with some cleansing ingredients (surfactants) to thicken them into gels. It also acts as a stabilizer for water-in-oil emulsions.

Est. %0.3
Function
Origin
Description is coming soon
Sodium Ascorbyl Phosphate
Est. %0.3
Function

Dimethicone Crosspolymer
Est. %0.3
Function
Origin
A 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.
Ethylhexylglycerin
Est. %0.3
Function
Origin
A preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
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.
Tocopheryl Acetate
Est. %0.3
Function
Origin
An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.
Hexyl Cinnamal

Est. %0.3
Function
Origin
Description is coming soon
Linalool
Est. %0.3

Ascorbic Acid
Est. %0.3
Function
Origin
