Ingredients Explained

These ingredients are found in both products.

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

Biotinoyl Tripeptide-1 is a lab-made molecule that combines two parts: biotin (vitamin B7) and Tripeptide-1. Together, they form a peptide that’s often used in hair and eyelash products.

In-vitro studies show this ingredient helps hair bulb cells grow faster and product more structual proteins. This helps keep hair securely anchored in the follicle.

A small human study using a mascara with 2% Biotinoyl Tripeptide-1 reported lashes that were about 17% longer and 19% thicker after one month.

One study from 2025 compared topical spray vs. a combined tropical/oral treatment. The combination group saw greater increases in total hair count.

While these early results are encouraging, most of the data comes from in-vitro experiments (in test tubes) or small, short-term trials.

Biotinoyl Tripeptide-1 looks promising for supporting hair strength and growth but there’s not yet strong clinical evidence to confirm how well it works.

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:

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

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

Isopentyldiol is a synthetic solvent, humectant, and emollient.

Humectants have the ability to attract and hold water while emollients create a thin film to prevent water from evaporating. This combination keeps your skin and hair soft and hydrated. Plus, isopentyldiol does not leave a sticky feeling behind.

As a surfactant, isopentyldiol is a hydrotrope. Hydrotropes help surfactants (cleansing agents) dissolve into water.

According to the manufacturer, using this ingredient with sorbitol boosts skin hydration and helps close cuticles of damaged hair.

This ingredient is water-soluble.

Panthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.

There are two forms of panthenol: D and L.

D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.

Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):

Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.

This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.

Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

This ingredient is also referred to as pro-vitamin B5.

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.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
