Saturday Skin Yuzu Vitamin C Lip Mask Versus Laneige Lip Sleeping Mask

Diisostearyl Malate is an emollient and most often used in lip products. It comes from isostearyl alcohol, a fatty acid, and malic acid, an AHA.

As an emollient, Diisostearyl Malate helps create a thin film on your skin to trap moisture in. This helps keep your skin soft and smooth.

This is a synthetic polymer used to thicken formulas, improve texture, and enhance spreadability.

Due to its large molecule size, this ingredient does not penetrate the skin and is considered well-tolerated.

Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.

Topically, glycerin does several things at once:

This ingredient is a synthetic ingredient with emollient and skin conditioner used to make skincare products feel more lightweight on the skin. It helps improve slip and spreadability without feeling greasy.

Because it is high molecular weight and lipophilic (oil loving), it remains on the surface of skin.

Hydrogenated Polyisobutene is a synthetic polymer. Polymers are compounds with high molecular weight. Hydrogenated Polyisobutene is an emollient and texture enhancer.

In one study, Hydrogenated Polyisobutene showed better skin hydration levels than Caprylic/Capric Triglyceride. As an emollient, it helps keep your skin soft and hydrated by trapping moisture in.

Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate (long name, huh?) is a synthetic antioxidant.

It is used to help stabilize other antioxidants or prevent the color from changing in a product.

Phytosteryl/Isostearyl/Cetyl/Stearyl/Behenyl Dimer Dilinoleate is an emollient ester.

As an emollient, it softens and hydrates your skin by locking moisture in. Its large, branched structure gives it a thick, cushiony feel without being greasy. This is why it shows up most often in lip balms, lipsticks, and other stick or balm formulas, where it adds gloss and helps hold waxes and pigments together.

Polybutene is used to help control the viscosity of a product. This just means it helps adjusts the texture.

It is a polymer and does not get absorbed into the skin due to its large size.

This ingredient is a form of glycerin with emulsifying and emollient properties.

As an emulsifier, this ingredient helps keep products together while adding a thick texture. The manufacturer states this ingredient has emollient properties. Emollients help keep the skin hydrated by trapping moisture in.

Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin. 

It’s often used to:

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

Euphorbia Cerifera wax comes from a shrub in Northern Mexico. It is used to stabilize formulations and has emollient properties.

Emollients form a thin layer on top of skin to prevent water from evaporating, keeping skin and lips hydrated.
