Key Benefits of Tarte Lid Lock Clay Eye Base

 
These are the key benefits you can expect from using Tarte Lid Lock Clay Eye Base:
 

🔵🔵🔵 Exceptionally Rich Moisturizer with the Right Occlusivity for Very Dry Skin

According to CreamScan analysis, Tarte Lid Lock Clay Eye Base is quite moisturizing, with a moisturizing rating of 5.5 out of 10.

Is it more humectant or occlusive? Significantly more occlusive. It has a low Humectancy of 1.0 out of 10 and a maximum Occlusivity of 10 out of 10, primarily due to the high content of Dimethicone (est. ≈22.0%), Euphorbia Cerifera (Candelilla) Wax (est. ≈3.0%) and Copernicia Cerifera (Carnauba) Wax (est. ≈2.0%).

This type of product, when used as a standalone moisturizer, can deliver an exceptional level of occlusive hydration that is adequate for dry to very skin. The occlusive profile of Tarte Lid Lock Clay Eye Base suggests a rich, thick texture, making it perfectly suited for dry skin.

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

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

Things to Be Aware Of: Tarte Lid Lock Clay Eye Base

 
CreamScan identified a few things to consider before adding Tarte Lid Lock Clay Eye Base to your skincare routine:
 

⚠️ Best for Very Dry Skin - May Be Too Thick for Other Skin Types

With exceptional occlusivity, this product is optimal for moisturizing dry and very dry skin but may be too thick for other skin types, including normal, and especially combination and oily skin.

If you have oily, combination, or normal skin and are considering purchasing this product for the first time, it might be a good idea to try a sample before buying.

⚠️ Needs to Be Paired with Extra Humectants for Optimal Moisturizing Efficacy

An ideal moisturizer for any skin type should balance the right level of occlusivity (depending on skin type) with a significant amount of humectants, while Tarte Lid Lock Clay Eye Base contains a low level of humectants.

People with dry skin would definitely benefit from adding more humectants to their moisturizing routine beyond what this product offers. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Tarte Lid Lock Clay Eye Base is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Retinyl Palmitate and Tetrahexyldecyl Ascorbate, 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.

While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

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.

Pros & Cons of Tarte Lid Lock Clay Eye Base

 
Here’s an overview of the pros and cons of Tarte Lid Lock Clay Eye Base to help you decide if it’s the right choice for your skincare routine:
 

🟩 Pros:

Exceptionally rich moisturizer with the right level of occlusivity to moisturize dry to very dry skin
 

⭕ Cons: 

⚠️ May feel too rich and thick on skin types other than dry
⚠️ Only if used as a standalone moisturizer - needs to be paired with extra humectants for optimal moisturizing efficacy
⚠️ Questionable anti-wrinkle efficacy
   

Summary: Tarte Lid Lock Clay Eye Base

 
Based on the ingredient list analysis, CreamScan AI suggests that Tarte Lid Lock Clay Eye Base
, as a moisturizer, provides an exceptional level of occlusive hydration that is adequate for dry to very skin, delivered in a rich, thick texture.
 
That said, there are some things about Tarte Lid Lock Clay Eye Base worth noting.
 
With its high occlusivity, Tarte Lid Lock Clay Eye Base is ideal for dry skin but may feel too thick on other skin types. If you have oily, combination, or normal skin, it’s a good idea to try a sample before purchasing.
 
If you use this product as your only moisturizer in a routine, please note that it contains only a small amount of humectants. Regardless of your skin type, adding extra humectants can enhance optimal moisturizing efficacy. Therefore, it may be worth pairing Tarte Lid Lock Clay Eye Base with a humectant-rich product, such as a serum, in your skincare routine.
 
If one of your main reasons for considering Tarte Lid Lock Clay Eye Base is its potential anti-aging effects, please note that, according to CreamScan analysis, its anti-wrinkle efficacy is questionable. None of the ingredients in this product provide substantial evidence of their anti-wrinkle efficacy according to CreamScan Research Evaluation Standards.

Ingredients explained

Isododecane
Est. %45
Function
Origin
IsododecaneAn emollient derived from petroleum with high spreadability. It is often used as a replacement for oils and silicones because it leaves no residue behind on the skin. When a product is labeled as “oil-free” it may contain isododecane instead of heavier oils.
Dimethicone
Est. %22
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.
Mica
Est. %11
Function
Origin
MicaA mineral powder made up of silicates with several functions (the main one being as a colorant). It has a shimmery appearance, making it highly desirable in certain cosmetic products. Mica also helps the product to apply more smoothly.
Polyethylene
Est. %6
Function
Origin
PolyethyleneCommonly used in dense plastic packaging, its primary function in skincare is as a film-forming agent, which protects the product from being easily rinsed away by water or sweat. It also controls viscosity by increasing the thickness of oily products.
Disteardimonium Hectorite
Est. %4
Function
Origin
Disteardimonium HectoriteA clay ingredient that functions primarily as a viscosity controlling agent that thickens all types of formulas. Disteardimonium hectorite imparts a smooth, velvety feel, making it a luxurious addition to any formula.
Euphorbia Cerifera (Candelilla) Wax
Est. %3
Function
Origin
Euphorbia Cerifera (Candelilla) WaxA thick wax obtained from the stems of the Candelilla, or wax plant that is native to Mexico and the southern USA. Its stems are covered in wax to protect the plant from water loss. It is an occlusive moisturizing and emollient ingredient.
Copernicia Cerifera (Carnauba) Wax
Est. %2
Function
Origin
Copernicia Cerifera (Carnauba) WaxObtained from the leaves of Carnauba wax palm, this occlusive, emollient, and film-forming wax is commonly used in lip products. It is comprised mainly of various wax esters and is one of the hardest and most resistant plant waxes.
Squalane
Est. %1.5
Function
Origin
SqualaneAn occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
Lecithin
Est. %1
Function
Origin
LecithinA 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.
Propylene Carbonate
Est. %0.3
Function
Origin
Propylene CarbonateA derivative of propylene glycol that is used most frequently as a solvent. Additionally, propylene carbonate serves as a viscosity controlling agent reducing the thickness of the products it is added to.
Hydrogenated Polybutene
Est. %0.3
Function
Origin
Hydrogenated Polybutene
Trihydroxystearin
Est. %0.3
Function
Origin
Trihydroxystearin
Tocopheryl Acetate
Est. %0.3
Function
Origin
Tocopheryl Acetate

An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.

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.

Kaolin
Est. %0.3
Function
Origin
KaolinA type of mineral clay milled into a white, very fine powder. It is able to absorb sweat and oil, which then helps to keep the skin matte. The larger particles of kaolin are used in skin scrubs as an abrasive ingredient.
Retinyl Palmitate
Est. %0.3
Function
Origin
Retinyl Palmitate

An esterified form of retinol – it combines retinol and palmitic acid into one molecule. Retinyl palmitate is less irritating than retinol but lacks clinical proves of its anti-aging and acne-reducing efficacy.

Tetrahexyldecyl Ascorbate
Est. %0.3
Function
Origin
Tetrahexyldecyl AscorbateA lipid-soluble form of vitamin C that is more stable and less irritating than ascorbic acid. According to a recent clinical study, THDA has all the capabilities of regular vitamin C, including anti-wrinkle and anti-pigment activity.
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.
Phenoxyethanol
Est. %0.3
Function
Origin
PhenoxyethanolThe 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.
