Review

Results you may expect from using LightStim PhotoSerum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using LightStim PhotoSerum:

  • Moderate moisturizing. It has a moisturizing rating of 4.1 out of 10.

How moisturizing is it?

Quite moisturizing: LightStim PhotoSerum has a moisturizing rating of 4.1 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a very high humectancy of 8.2 out of 10, primarily due to the high content of Sodium Hyaluronate (est. ≈2.5%) and Plankton Extract (est. ≈2.0%).

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, LightStim PhotoSerum has a zero anti-wrinkle rating.

It contains Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7, two ingredients 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, could deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Ingredients explained

Water
Est. %80
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.
Cyclopentasiloxane
Est. %6
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.
Cyclohexasiloxane
Est. %4
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.
Sodium Hyaluronate
Est. %2.5
Function
Origin

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.

Plankton Extract
Est. %2
Function
Origin
An extract from a mixture of various tiny marine animals, algae, seaweeds, and microscopic organisms jointly called plankton. One patent refers to it as a moisturizing humectant ingredient.
Glycerin
Est. %1.5
Function
Origin

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

Butylene Glycol
Est. %1.3
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.
Carbomer
Est. %1
Function
Origin
A synthetic ingredient with the ability to gel water. When used in emulsions, such as lotions and creams, carbomer can also act as an emulsion stabilizer.
Polysorbate 20
Est. %0.3
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.
Palmitoyl Tripeptide-1
Est. %0.3
Function
Origin

A small peptide consisting of three amino acids with anti-wrinkle effects. Together with Palmitoyl Tetrapeptide-7, it is a part of the popular anti-wrinkle complex called Matrixyl™ 3000.

Palmitoyl Tetrapeptide-7
Est. %0.3
Function
Origin

A synthetic peptide that mimics the activity of immunoglobulin G and signals to the skin to stop the inflammation. It has been shown in studies to reduce wrinkles and enhance collagen content.

Saccharide Isomerate
Est. %0.3
Function
Origin
A naturally-derived humectant that provides moisturization at low levels and is less sticky than other humectants like glycerin.
Oleth-10
Est. %0.3
Function
Origin
Description is coming soon
Lecithin
Est. %0.3
Function
Origin
A humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.
Ergothioneine
Est. %0.3
Function
Origin
A naturally-occurring amino acid that functions as a powerful and versatile antioxidant.
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.
Phenoxyethanol
Est. %0.3
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.
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.
Tromethamine
Est. %0.3
Function
Origin
An ingredient based on amino acids that is commonly used as a pH adjuster. It has a high pH, which means that it is basic (alkaline), so adding tromethamine to a skincare product will increase its overall pH level.
