How moisturizing is it?

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.6 out of 10 and a very high humectancy of 8.1 out of 10, primarily due to the high content of Butylene Glycol (est. ≈4.0%) and Glycerin (est. ≈2.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Stila One Step Prime Serum Primer has a zero anti-wrinkle rating.

It contains some ingredients marketed as effective in reducing wrinkles, specifically Tetrahexyldecyl Ascorbate, Magnesium Ascorbyl Phosphate, Retinyl Palmitate, and Camellia Sinensis Leaf Extract. 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. %70
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.
Butylene Glycol
Est. %4
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.
Octyldodecyl Neopentanoate
Est. %3
Function
Origin
A synthetic emollient ester. This clear, colorless liquid has a unique sensorial profile that is light and silky, with good lubricity.
Glycerin
Est. %2
Function
Origin

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

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.

Function
Origin
A silicone-based emulsifier that has the ability to create non-sticky and non-greasy formulas.

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.
Dimethicone
Est. %0.3
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.
Aluminum Hydroxide
Est. %0.3
Function
Origin
A white mineral powder, also known as alumina, that is derived from aluminum metal. It is frequently used as an abrasive in exfoliating products and as a thickener. Aluminum oxide is also a great opacifier.
Sodium Hydroxide
Est. %0.3
Function
Origin

An ingredient that is able to bring the pH of a product up, thereby making it less harsh on the skin.

Caprylyl Glycol
Est. %0.3
Function
Origin
An emollient that improves product spreadability and offers a silky feel on the skin. It also acts as a preservative booster that improves the efficacy of other preservatives. According to the manufacturer, it is also a humectant moisturizer.
Titanium Dioxide (CI 77891)
Est. %0.3
Function
Origin
One of two the most commonly used mineral sunscreens. It can absorb UV light, including UVB – which causes burning, tanning, and even skin cancer. Also used as a colorant, titanium dioxide gives a product a bright white color.
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.

Sodium Dehydroacetate
Est. %0.3
Function
Origin
A sodium salt of dehydroacetic acid that is most commonly used as a preservative. It is a strong fungicide and a moderate bactericide, which makes it an effective broad-spectrum preservative.

Phytantriol
Est. %0.3
Function
Origin

Hexylene Glycol
Est. %0.3
Function
Origin
A multifunctional ingredient that is best known for its use as a solvent. It can dissolve both water-based ingredients and oils. For this reason, it can also function as an emulsifier, allowing oil and water ingredients to mix and remain stable.
Glyceryl Acrylate/Acrylic Acid Copolymer
Est. %0.3
Function
Origin
A synthetic humectant moisturizer often paired with glycerin. It also functions as a viscosity-controlling agent that creates gel-like formulas with thicker textures.

Magnesium Ascorbyl Phosphate
Est. %0.3
Function
Origin
One of the best-researched derivatives of vitamin C. It is more resistant to light and air and retains all the properties of ascorbic acid – antioxidant, collagen-boosting, and anti-pigmentation, but with less irritation.
Retinyl Palmitate
Est. %0.3
Function
Origin
An esterified form of retinol – it combines retinol and palmitic acid into one molecule. Retinyl palmitate is less irritating than retinol but also much less effective in its anti-aging and acne-reducing effects.
Zinc Oxide
Est. %0.3
Function
Origin
