Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Arginine is a semi-essential amino acid. This just means our bodies can product a bit on its own, but sometimes needs a little boost from food sources.
It is a part of your skin's natural moisturizing factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy.
Here's an interesting thing about Arginine: your skin converts it into urea through the Krebs-Henseleit urea cycle. Urea is one of the most effective humectants your skin naturally produces.
A clinical study showed applying 2.5% arginine hydrochloride to atopic dermatitis skin showed significant urea levels in the stratum corneum and improved moisture in just four weeks.
Arginine is also a precursor to nitric oxide; nitric oxide improves microcirculation and supports wound healing and collagen synthesis.
One study found that an amino acid complex containing Arginine reduced skin irritation, improved hydration, and accelerated skin repair in clinical / in-vivo studies.
Arginine itself is an amino acid and not a fatty acid, oil, or ester. On its own, it's not a direct food source for Malassezia, or the yeast that causes fungal acne.

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.

Myristoyl Pentapeptide-17 is a five amino peptide attached to myristic acid to help it absorb better into skin. It's mostly used for lash growth and as a delivery vehicle for other ingredients.
The myristic acid "tail" is basically a delivery upgrade that helps the peptide mix with your skin's natural oils so it can get where it needs to go.
In your eyelash follicles, it activates the keratin gene and promotes nutrient absorption into the follicle. This translates to thicker and longer eyelashes over time.
Besides stimulating keratin production for lash growth, this ingredient enhances the delivery of other active ingredients in a formula.
The clinical evidence is still pretty early-stage at this point. A 90 day study in 29 participants found improvements in lash length (10.52%), volume (9.3%), thickness (35%), and curl (50.83%) with no adverse reactions reported.
You might have heard that eyelash serums can cause pigmentation change in eye color to turn eyes brown. This is associated with a different class of lash serum ingredients: prostaglandin analogs.
Myristoyl Pentapeptide-17 is a different thing entirely and has no known association with iris pigmentation changes. The 90 day study noted no adverse effects around the eye area at all.

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!
