Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Urea 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.

Phytosphingosine is a phospholipid naturally found in our skin. It helps moisturize, soothe, and protect skin.
Phytosphingosine is already present in our skin. On our skin, it is a building block for ceramides.
Phytosphingosine tells our skin to increase its natural moisturizing factor (NMF). The NMF is responsible for hydration, a strong barrier, and plasticity. Our NMF decreases with age. Increasing NMF leads to more healthy and hydrated skin.
Studies show products formulated with NMF ingredients help strengthen our skin's barrier. Having a healthy skin barrier reduces irritation and increases hydration. Our skin barrier is responsible for having plump and firm skin. It also helps protect our skin against infection, allergies, and inflammation.

Sodium Lactate is the sodium salt of lactic acid, an AHA. It is a humectant and used to adjust the pH of a product.
Sodium Lactate is part of our skin's NMF, or natural moisturizing factor. Our NMF is essential for the hydration of our top skin layers and plasticity of skin.
It also influences our skin's natural acid mantle and pH, which protects our skin from harmful bacteria.
Our NMF is formed from amino acids, lactic acid, sugars, minerals, peptides, and electrolytes. As we age, our NMF naturally depletes. Other sources of NMF depletion include harsh and drying ingredients such as denatured alcohol. Sodium lactate can help replenish our NMF, leading to more hydrated and plump skin.
High percentages of Sodium Lactate can have an exfoliating effect.
Sodium Lactate is produced from fermented sugar.
