Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.
Learn more about Caprylyl GlycolEthylhexylglycerin (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.
Palmitoyl Tetrapeptide-7 is a lab-made peptide with anti-inflammatory and skin-repairing benefits. It's made up of four amino acids (glycine, glutamine, proline, and arginine) and palmitic acid (which helps it penetrate skin more effectively).
This ingredient helps reduce inflammation by limiting the production of interleukin-6 (IL-6), a chemical that triggers inflammatory responses, particularly after UV exposure.
Less inflammation = slower collagen breakdown and a longer-lasting, youthful appearance.
Palmitoyl Tetrapeptide-7 also stimulates collagen production and supports a healthier skin barrier.
Over time, this can improve skin firmness, hydration, and reduce the appearance of fine lines. It’s commonly paired with Palmitoyl Tripeptide-1 in the well-known Matrixyl 3000 complex for enhanced anti-aging effects.
This ingredient has been shown to be effective and safe in cosmetic use and you'll typically find it in small amounts (less than 0.01%).
Due to its palmitic acid base, it may not be safe for Malassezia folliculitis.

Learn more about Palmitoyl Tetrapeptide-7Palmitoyl Tripeptide-1 is also known as pal-GHK. It is made up of 3 amino acids and palmitic acid, a fatty acid that helps it absorb into skin more easily.
This peptide is as a signal peptide, meaning it tells the skin to produce more collagen. Collagen is the key protein that helps form the skin's structure and keep it plump, firm, and hydrated.
By boosting collagen production, this ingredient supports a stronger skin barrier and helps reduce the appearance of wrinkles.
You'll most likely see this ingredient paired with Palmitoyl Tetrapeptide-7 in the well-known Matrixyl 3000 complex. While results from in-house testing should be viewed cautiously, this peptide duo is among the most studied and widely used in modern skincare.
Due to its palmitic acid base, this ingredient may not be safe for Malassezia folliculitis.

Learn more about Palmitoyl Tripeptide-1Sodium PCA is the sodium salt of pyroglutamic acid. It is naturally occurring in our skin's natural moisturizing factors where it works to maintain hydration.
The PCA stands for pyrrolidone carboxylic acid, a natural amino acid derivative.
This ingredient has skin conditioning, anti-inflammatory, and humectant properties. Humectants help hydrate your skin by drawing moisture from the air. This helps keep your skin moisturized.
Learn more about Sodium PCAUrea is also called carbamide and is the diamide of carbonic acid. In cosmetics, urea is used to hydrate the skin. It also provides exfoliation in higher concentrations.
As a humectant, urea helps draw moisture from the air and from deep within the skin. This helps hydrate your skin. Studies show urea is an effective moisturizer for dry skin conditions. 40% urea is typical in medications for treating eczema and other skin conditions.
Urea has the strongest exfoliation effect in concentrations higher than 10%. It is a keratolytic agent, meaning it breaks down the keratin protein in the top layer of skin. This helps remove dead skin cells and flaking skin.
In medicine, urea has been shown to help increase the potency of other ingredients, such as fungal treatments.
Humans and animals use urea to metabolize nitrogen-containing compounds. Urea is highly soluble in water. Once dissolved, it is neither acidic nor alkaline.
