Miracle Lash Ingredients Decoded: 5 Key Components

Miracle Lash lists only a handful of ingredients, and as of this month, reading them line by line shows what the formula centers on and what the label leaves out. I went through each entry so you can decide before paying $79.

Key Takeaways:

Four active-style ingredients are named on the label (Myristoyl Pentapeptide-17, Vitamin B5, grape stem cell extract, glycerin), and the formula contains no prostaglandin analogues.
Four ingredient families are listed as absent: parabens, sulfates, phthalates and mineral oil. That is a list of exclusions, not proof of how the serum performs.
The full ingredient list and the concentration of every ingredient are not published, so you cannot judge dose, order or the filler base before buying.

Quick Answer: 5 Parts of the Miracle Lash Formula in Plain Words

What is in the serum: Four named ingredients in a clear 5 mL pen, with no prostaglandin analogues. That is the direct answer to the question.
The five components: The peptide, Vitamin B5, grape stem cell extract and glycerin, plus the formula’s overall keratin-support approach. Each has a general cosmetic role, but no Miracle Lash-specific results are published.
How the B5 and grape extract pair works: They read as the care-and-condition side of the formula, with the peptide positioned around keratin support.
What it leaves out: Parabens, sulfates, phthalates and mineral oil. A free-from list says what was removed, not whether the rest works.
What the label hides: The complete ingredient list and every concentration. Ask for the list first if your eyes are sensitive.

What is in Miracle Lash serum?

Miracle Lash is a clear peptide eyelash serum sold in a 5 mL pen with a fine brush tip. This means it is a leave-on conditioning product you brush along the lash line, not a prescription treatment. The vendor names four key ingredients: Myristoyl Pentapeptide-17, Vitamin B5, grape stem cell extract and glycerin. If you are weighing up the Miracle Lash, read the verdict first.

The formula uses no prostaglandin analogues. That is the main reason some women pick it, since prostaglandin-based serums are the group with the more familiar list of eye-area side effects. Think of Miracle Lash as the gentler, slower route.

The next sections go through the list one ingredient at a time, then cover what is left off the label. One point to hold onto: the vendor does not publish the full ingredient list or any concentrations.

Miracle Lash ingredient list: what does each of the five components do?

Cosmetics generally give each listed ingredient a specific conditioning, hydrating or signalling role. A common assumption is that a named ingredient means a proven result. The reality is that the roles below come from general cosmetic knowledge, and the vendor has not shown Miracle Lash-specific results for any single one.

Ingredient	What it is	What it is generally known for	What is not shown for Miracle Lash itself
Myristoyl Pentapeptide-17	A short-chain peptide	Marketed for keratin support in lashes and brows	Its concentration and any product-specific result
Vitamin B5	Panthenol family ingredient	Conditioning and binding moisture to the hair shaft	Its concentration and effect on lash fullness
Grape stem cell extract	Plant-derived cosmetic extract	Antioxidant positioning in skin and hair products	Its concentration and any measured benefit
Glycerin	A humectant	Drawing water to the surface so lashes feel softer	Its place in the ingredient order

The fifth component is the formula’s overall approach to supporting lash keratin, since the label names only four ingredients and does not publish concentrations. For the peptide’s detail, see this guide to myristoyl pentapeptide-17. None of these ingredients is shown to regrow lashes or treat lash loss.

How do Vitamin B5 and grape stem cell extract fit into the formula?

Vitamin B5 and grape stem cell extract support the conditioning side of the formula rather than a growth claim. Vitamin B5 is a moisture-retaining conditioner. Grape stem cell extract is a plant-derived cosmetic extract. Together they read as a care-and-condition pairing, while the peptide is the ingredient positioned around keratin support. A closer look at vitamin b5 for eyelashes covers that ingredient on its own.

The roles are general cosmetic knowledge. The label does not show how much of either is present.

Buyer feedback fits a conditioning-style formula. Verified Amazon buyers mostly call the serum gentle, and the rating sits at 3.8 out of 5 from 56 ratings as of Oct 2026. Results range from noticeably fuller lashes after a month to slight or no change, so the pairing does not explain any one buyer’s result.

Is Miracle Lash free of parabens, sulfates, phthalates and mineral oil?

Yes, the vendor states that it formulates Miracle Lash without parabens, sulfates, phthalates and mineral oil. Here is what the vendor lists as absent or true of the product:

Parabens: The vendor says none are used. These are a common preservative family that some people prefer to avoid.
Sulfates: The vendor says none are used. They are cleansing agents more often found in washes than in a leave-on serum.
Phthalates: The vendor says none are used. They sometimes appear in fragranced products, and this serum is unscented.
Mineral oil: The vendor says the formula contains none, which fits the thin, watery texture buyers describe.
Prostaglandin analogues: The vendor says the formula contains none, which is what makes it a prostaglandin-free lash serum.
Cruelty-free: The vendor states the serum is not tested on animals.
Made in USA: The vendor states it is manufactured in the United States.

A free-from list tells you what was left out. It does not tell you what is in the rest of the bottle, and it does not tell you whether the serum works. These are vendor statements, and with the full list unpublished, you cannot fully check them from the label alone.

What does the Miracle Lash label not tell you?

The vendor does not publish the full ingredient list or any ingredient concentrations. That is the biggest gap in the product’s ingredient transparency.

Why does it matter? Picture a recipe that names the spices but not the quantities. Without the full list you cannot check for a personal allergen. You cannot see which ingredients sit at the top, and you cannot tell whether a named active, such as the peptide or glycerin, is present at a meaningful level.

The label does give texture facts: thin, watery and unscented. Those describe feel, not ingredient strength.

This gap is a real consideration for sensitive eyes. Among 56 Amazon ratings, two buyers reported stinging or irritation when the serum reached the eye, and one reported a stye. Most buyers describe it as gentle, but that does not make it suitable for everyone.

You have two practical steps. Ask the vendor for the complete list before buying if you have sensitivities, and use the stated 365-day money-back guarantee as a backstop. If you want to know how long one tube lasts in practice, see how long does miracle lash last.

What the Ingredient List Means for Your Decision

The named ingredients are mild, familiar cosmetic ingredients, which matches what most buyers say about gentleness. The concentrations are unknown, which matches the mixed results. If thinning has progressed with age, why do eyelashes thin with age explains what a conditioning serum can and cannot address, and lash serum for mature lashes covers what to try when a serum seems stuck.

Frequently Asked Questions

Does Miracle Lash contain any prostaglandin analogues like the ones in prescription lash serums?

No. The vendor states the formula contains no prostaglandin analogues, which is why it calls the serum prostaglandin-free. The named ingredients are a peptide, Vitamin B5, grape stem cell extract and glycerin, which work on conditioning and keratin support rather than the mechanism prostaglandin serums use.

Does Miracle Lash have a scent or a thick texture?

Buyers and the vendor describe it as thin, watery, unscented and quick to dry. That feel suits a pen applied along the lash line, but it says nothing about how much of any active ingredient is in the bottle.

Where is Miracle Lash made, and is it tested on animals?

The vendor states it is made in the USA and is cruelty-free. These are manufacturer claims shown on the product page, so treat them as stated by the seller rather than independently verified.
