Does Rare beauty Pore Diffusing Primer - Always an Optimist Collection work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Rare beauty Pore Diffusing Primer - Always an Optimist Collection:

  • Moderate moisturizing. It has a moisturizing rating of 5.2 out of 10.

Well-suited moisturizer for normal skin with a relatively lightweight texture

According to CreamScan analysis, Rare beauty Pore Diffusing Primer - Always an Optimist Collection is quite moisturizing, with a moisturizing rating of 5.2 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a high humectancy of 6.3 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈2.5%) and Butylene Glycol (est. ≈2.0%), and a moderate occlusivity of 4.0 out of 10, mainly due to the significant content of Dimethicone (est. ≈7.5%).

This type of moisturizer is well-suited for people with normal skin. It combines a high concentration of humectants with a significant amount of occlusive ingredients to deliver effective dual-action moisturizing for normal skin.

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

Questionable anti-wrinkle efficacy

According to CreamScan analysis, Rare beauty Pore Diffusing Primer - Always an Optimist Collection has a zero anti-wrinkle rating.

It contains Camellia Sinensis Leaf Extract and Melia Azadirachta Leaf Extract, 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 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, 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.

Dimethicone
Est. %7.5
Function
Origin
DimethiconeThe 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.
Methyl Trimethicone
Est. %5
Function
Origin
Methyl TrimethiconeA lightweight and volatile silicone known for its excellent solvency. This silicone has a silky, cushiony feel with excellent lubricity and is commonly used as an emollient in silicone-based skincare products.
Dipropylene Glycol
Est. %3
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.
Glycerin
Est. %2.5
Function
Origin

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

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.

Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer
Est. %1.5
Function
Origin
Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer
Dimethicone/Vinyl Dimethicone Crosspolymer
Est. %1.3
Function
Origin
Dimethicone/Vinyl Dimethicone CrosspolymerThis ingredient can refer to several kinds of dimethicone crosspolymers. Like other silicones, it makes products feel slippery and non-greasy but can also increase the thickness or improve the water-resistance of a formula.
Cetyl PEG/PPG-10/1 Dimethicone
Est. %1
Function
Origin
Cetyl PEG/PPG-10/1 DimethiconeA silicone-based powerful emulsifier that helps to create lightweight and pleasant feeling lotions and creams.
Sodium Chloride
Est. %0.3
Function
Origin
Sodium Chloride

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.

Dimethicone/PEG-10/15 Crosspolymer
Est. %0.3
Function
Origin
Dimethicone/PEG-10/15 CrosspolymerA self-emulsifying surfactant, which means that it can help facilitate the formation of water-in-silicone emulsions. This results in lightweight formulas with a soft finish. It can also act as a film-former and thickener.
Silica
Est. %0.3
Function
Origin
SilicaA widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
Propanediol
Est. %0.3
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.
Sodium Benzoate
Est. %0.3
Function
Origin
Sodium BenzoateA preservative that usually works in combination with other preservatives. It has to be at low pH (<5.5) to be effective.
Potassium Sorbate
Est. %0.3
Function
Origin
