Also known as: Eau, Aqua, Purified Water, Aqua / Water, Distilled Water, Deionized Water, and Spring Water
Community rating: Loved

Water is the most common cosmetic ingredient of all. It often makes up the largest portion of a product, and is thus typically found at (or near) the top of an ingredients list.

In most cases, the purpose of water within an ingredient list is to act as a solvent - this means it's there to help dissolve other ingredients into the formulation.

Water also happens to be necessary for all life on Earth. If you see this, drink a glass of water. Stay hydrated!

Humectant, Skin Conditioning, Skin Protecting, Solvent
Also known as: Vegetable Glycerin, Glycerine, and Glycerol
Community rating: Loved

Glycerin is already naturally found in your skin and helps moisturize and protect your skin. A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

Glycerin is a humectant, helping the skin retain moisture by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin. Having moisturized skin helps improve the skin barrier. Your skin barrier protects against skin 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, animal sources include tallow. It is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English while British English uses Glycerol/Glycerine.

Humectant

Glucose is a simple sugar and is the most important source of energy in all organisms. In skincare, glucose is used to hydrate the skin. It also acts as a prebiotic for our natural biome.

As a humectant, glucose draws moisture from the air and from deeper levels in the skin. This helps hydrate skin.

Our skin's natural microbiome contains many saccharides that act as prebiotics. These prebiotics help strengthen our skin's microbiome. Having a healthy microbiome helps protect our skin from harmful bacteria and other contaminants.

Studies show glucose may help with fading discoloration and pigmentation. This is because our skin metabolizes glucose into lactic acid. Lactic acid is an AHA that helps exfoliate the top layer of skin.

Plants and algae make glucose during the process of photosynthesis. It is then used to make cellulose, the building blocks of cell walls.

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.
