Key Benefits of Tiam Vitamin C 24 Surprise Serum

 
These are the key benefits you can expect from using Tiam Vitamin C 24 Surprise Serum:
 

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Tiam Vitamin C 24 Surprise Serum is quite moisturizing, with a moisturizing rating of 5.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.2 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Propanediol (est. ≈45.0%), Glycerin (est. ≈6.0%) and Pentylene Glycol (est. ≈3.0%).

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.

A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - 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.

Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, Tiam Vitamin C 24 Surprise Serum has a modest level of anti-wrinkle efficacy, rated 2.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈22.0%), 
 or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
Among others, Tiam Vitamin C 24 Surprise Serum also contains contains 3-O-Ethyl Ascorbic Acid and Folic Acid, 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 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, 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.

Rich in Skin-Protecting Antioxidants

We estimate that Tiam Vitamin C 24 Surprise Serum is rich (> 3%) in antioxidants, specifically Ascorbic Acid (est. ≈22.0%) and 3-O-Ethyl Ascorbic Acid (est. ≈11.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

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

Ingredients explained

Propanediol
Est. %45
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.
Ascorbic Acid
Est. %22
Function
Origin
Ascorbic Acid

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.

3-O-Ethyl Ascorbic Acid
Est. %11
Function
Origin
3-O-Ethyl Ascorbic AcidA derivative of vitamin C. Its stability in skincare formulations is better than ascorbic acid’s, although clinical studies are yet to indicate whether it has the same collagen-boosting benefits.
Glycerin
Est. %6
Function
Origin
Glycerin

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

Dipropylene Glycol
Est. %4
Function
Origin
Dipropylene GlycolA clear, colorless liquid that has several uses. One of its main functions is as a solvent. Dipropylene glycol is also used to reduce the thickness of skincare products.
Pentylene Glycol
Est. %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.

Butylene Glycol
Est. %2
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.

Potassium Hydroxide
Est. %1.5
Function
Origin
Potassium HydroxideA very alkaline ingredient, meaning that it has a high pH. Potassium hydroxide is therefore useful in bringing a low pH in a cosmetic product up to a more neutral, skin-safe level.
Madecassoside
Est. %1
Function
Origin
MadecassosideAn isolated Gotu Kola compound. It helps to increase collagen and hyaluronic acid production in the skin and assists in wound healing.
Glutathione
Est. %0.3
Function
Origin
GlutathioneA naturally occurring tripeptide that combats free radicals and acts as a reducing agent.
Ferulic Acid
Est. %0.3
Function
Origin
Ferulic AcidA plant-based phenolic acid with powerful and scientifically proven antioxidant properties. It enhances the effects of vitamins C and E, as well as the UV protective effects of sunscreens.
Carnitine
Est. %0.3
Function
Origin
Carnitine
Pyridoxine
Est. %0.3
Function
Origin
PyridoxinePyridoxine, also known as vitamin B6, is required by the body to produce amino acids, carbohydrates, and lipids. Its benefits in skincare have not been researched as of yet.
Biotin
Est. %0.3
Function
Origin
BiotinBiotin is an important nutrient that can cause weak hair and nails if deficient. Unfortunately, while biotin supplements have promising studies, topical biotin in creams and serums doesn’t have a large body of evidence to support its use.
Inositol
Est. %0.3
Function
Origin
InositolA humectant moisturizing, sugar-like compound that is present in all the cells of the body, but especially the brain. It is manufactured from sugar beets or carob tree pods for skincare purposes.
Folic Acid
Est. %0.3
Function
Origin
Folic AcidA critical vitamin for the body that needs more research for topical applications.
Tocopherol
Est. %0.3
Function
Origin
Tocopherol

Simply another name for vitamin E. Tocopherol is a fantastic ingredient and especially beneficial for dry and inflamed skin. It has occlusive moisturizing, emollient, antioxidant, and photoprotective properties.
