Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Dimethyl Isosorbide is a solvent and helps deliver actives into your skin. It is created from sorbitol.

As a solvent, dimethyl isosorbide helps dissolve other ingredients. This helps ensure even distribution of an ingredient. It may also be used to decrease the thickness of a product.

Studies show dimethyl isosorbide is able to penetrate skin to deliver other ingredients into the skin, making them more effective.

Skin Conditioning

Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.

You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.

Emollient, Humectant, Skin Conditioning

Caprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.

It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.

Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.

This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.

Preservative

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.

Drunk Elephant Vit C serum is a decent alternative to Skinceuticals C E Ferulic, as it is about half as expensive (DE ~$3.71/ml, Skinceuticals ~$6.93/ml). However, I do find that the consistency is a bit tacky and difficult to spread around. The product smells pretty strongly of hot dogs, but you do get used to this. On the plus side, I appreciate that the serum uses Ascorbic Acid (rather than a Show more
