Does Tirtir Pure Vitamin C24 Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Tirtir Pure Vitamin C24 Serum:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.0 out of 10.
  • Considerable anti-wrinkle efficacy: Tirtir Pure Vitamin C24 Serum has an anti-wrinkle rating of 5.5 out of 10, indicating a moderate ability to reduce wrinkles.
  • Antioxidant protection.

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

According to CreamScan analysis, Tirtir Pure Vitamin C24 Serum is quite moisturizing, with 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 Propanediol (est. ≈50.0%) and Betaine (est. ≈16.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

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.

Considerable anti-wrinkle efficacy

According to CreamScan analysis, Tirtir Pure Vitamin C24 Serum has a moderate anti-wrinkle rating of 5.5 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

  • Asiaticoside (est. ≈0.3%),
     derived from the plant Centella asiatica, an ingredient with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 27 participants (Lee et al.). This study demonstrated that a cream containing 0.1% asiaticoside reduced the average wrinkle depth by 8% after 12 weeks of use, compared to a vehicle (the same formulation without asiaticoside).
  • Ascorbic Acid (est. ≈32.0%),
     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, Tirtir Pure Vitamin C24 Serum also contains some ingredients often marketed as effective in reducing wrinkles, specifically Centella Asiatica Extract, Centella Asiatica Leaf Extract, Asiatic Acid, Madecassic Acid, and Acetyl Hexapeptide-8. 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 Tirtir Pure Vitamin C24 Serum is rich (> 3%) in antioxidants, specifically Ascorbic Acid (est. ≈32.0%).

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.

Ingredients explained

Propanediol
Est. %50
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. %32
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.

Betaine
Est. %16
Function
Origin
BetaineAn ingredient derived from the sucrose in sugar beets. It has a negative chemical charge and a positive chemical charge on the same molecule. This allows betaine to be hygroscopic or humectant and thus provide moisturization by drawing water to the skin.
Bisabolol
Est. %0.3
Function
Origin
Bisabolol

An anti-inflammatory compound found naturally in German chamomile essential oil. It has a pleasant, sweet, and floral scent. Bisabolol also has soothing and anti-inflammatory properties but can cause an allergic reaction in more sensitive individuals.

Water
Est. %0.3
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. %0.3
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.

1,2-Hexanediol
Est. %0.3
Function
Origin
1,2-HexanediolA multi-functional formula helper. It is a well-studied preservtive against bacteria and can help pigments and fragrances disperse evenly in a formula.
Centella Asiatica Root Extract
Est. %0.3
Function
Origin
Centella Asiatica Root Extract
Centella Asiatica Extract
Est. %0.3
Function
Origin
Centella Asiatica ExtractAn extract from the leaves of the Gotu kola. It is used in skincare for its antioxidant, wound healing, anti-inflammatory, and anti-aging properties. It increases the production of collagen and hyaluronic acid in the skin.
Centella Asiatica Leaf Extract
Est. %0.3
Function
Origin
Centella Asiatica Leaf ExtractA well-researched soothing, wound-healing, and promising anti-aging extract that is obtained from the leaves of the Gotu Kola.
Soluble Collagen
Est. %0.3
Function
Origin
Soluble CollagenA protein obtained from farm or marine animals. Collagen molecules are too big to penetrate the skin so when they are applied via a skincare product they sit on top of the skin and act as humectant moisturizers.
Hydrolyzed Collagen
Est. %0.3
Function
Origin
Hydrolyzed Collagen

A humectant, film-forming, and emollient mixture of various proteins and peptides that were created by cutting the huge molecules of normal collagen into smaller pieces for better absorption. It also has some antioxidant properties.

Atelocollagen
Est. %0.3
Function
Origin
AtelocollagenA collagen molecule that has precisely the same properties as the regular collagen – a fantastic humectant moisturizer.
Asiatic Acid
Est. %0.3
Function
Origin
Asiatic AcidA compound isolated from Gotu Kola, a promising anti-wrinkle medicinal plant from Southeast Asia. It is claimed to increase the production of collagen and help with the wound healing process.
Madecassoside
Est. %0.3
Function
Origin
MadecassosideAn isolated Gotu Kola compound. It helps to increase collagen and hyaluronic acid production in the skin and assists in wound healing.
Madecassic Acid
Est. %0.3
Function
Origin
Madecassic AcidAn isolated bioactive compound from Gotu Kola. It increases collagen and hyaluronic acid production in the skin and helps to treat wounds, scars, and burns.
Asiaticoside
Est. %0.3
Function
Origin
Asiaticoside

A Gotu Kola or Centella Asiatica derivative with confirmed anti-wrinkle efficacy.

Acetyl Hexapeptide-8
Est. %0.3
Function
Origin
Acetyl Hexapeptide-8

A small synthetic peptide that is thought to act similarly to Botox by calming contractions of the facial muscles and reducing expression wrinkles. The effect is only temporary and it does not improve the skin structure in any way.
