Can Vaseline Make Your Eyelashes Grow? The Surprising Truth Revealed
Have you ever stared in the mirror, wishing for longer, fuller, more fluttery eyelashes, and then glanced over at that humble, blue-and-white jar of Vaseline sitting on your shelf? The question "can Vaseline make your eyelashes grow" is one of the most persistent beauty myths, passed down through generations like a secret family recipe. It’s a tantalizing thought: a cheap, accessible, multi-purpose product could be the key to the lashes of your dreams. But before you grab a cotton swab and start applying, it’s crucial to separate fact from folklore. This deep dive will explore the science of lash growth, the actual properties of petroleum jelly, and what experts really say about this widely debated beauty hack. We’ll uncover whether Vaseline is a miracle grower or simply a good conditioner, and explore safer, more effective alternatives for achieving the dramatic lashes you desire.
Understanding the Star of the Show: What Exactly Is Vaseline?
To solve this mystery, we must first understand our suspect. Vaseline, a brand name that has become synonymous with petroleum jelly, is a semi-solid mixture of hydrocarbons derived from petroleum. Its primary component is petrolatum, a highly refined and purified substance known for its incredible ability to create an occlusive barrier on the skin. This barrier is its superpower and, arguably, the source of the confusion.
For over 150 years, Vaseline has been a staple in medicine cabinets worldwide, trusted for its versatility. It’s used to protect minor cuts and scrapes, prevent diaper rash, moisturize severely dry skin, and even as a makeup remover for stubborn products. Its core function is protection and moisturization. It sits on top of the skin, sealing in existing moisture and shielding the area from external irritants and moisture loss. It does not contain any active ingredients, hormones, or stimulants that are biologically designed to influence or accelerate the natural growth cycle of hair follicles, including those on your eyelids. This fundamental fact is the cornerstone of understanding its relationship with your eyelashes.
The Biology of Beauty: How Do Eyelashes Actually Grow?
Before we can judge if something makes lashes grow, we need to know what "grow" means in the first place. Eyelash growth follows a specific, genetically predetermined cycle, much like the hair on your head. This cycle consists of three distinct phases:
- The Anagen Phase (Growth Phase): This is the active growth period where the lash follicle is producing new cells. For eyelashes, this phase lasts between 30 to 45 days. The length of this phase ultimately determines the maximum length your lash can reach. Once an anagen phase ends, that specific lash will stop growing, no matter what you apply to it.
- The Catagen Phase (Transition Phase): A short, about 15-day period where the lash follicle shrinks and detaches from its blood supply. Growth stops completely during this phase.
- The Telogen Phase (Resting Phase): This is the final resting stage, lasting roughly 100 days. The lash is fully formed but dormant. Eventually, it will fall out naturally, and a new anagen phase will begin in the follicle, starting the cycle over.
At any given time, your upper eyelid has about 150-200 lashes, with each follicle operating on its own independent schedule. This is why you don’t lose all your lashes at once. The key takeaway is that you cannot indefinitely prolong the anagen phase or force a follicle into a new anagen phase with a topical occlusive like Vaseline. Any product claiming to do so would be acting as a pharmaceutical drug, subject to rigorous FDA testing and approval, which Vaseline is not.
Myth vs. Reality: Can Vaseline Actually Stimulate Growth?
Now, to the heart of the matter. The claim that Vaseline makes eyelashes grow is a classic case of confusing conditioning with growth stimulation. Here’s the breakdown:
The Reality (What Vaseline Can Do):
- Intense Moisturization: By forming a seal, Vaseline prevents transepidermal water loss. This can hydrate the lash shaft and the follicle area, preventing brittleness and breakage.
- Protection: It can shield lashes from harsh environmental factors like wind and dry air, and may even create a barrier against mascara drying them out.
- The Illusion of Fullness: Well-hydrated, less brittle lashes are less likely to snap off prematurely. By reducing breakage, you allow your lashes to reach the full, natural length their anagen phase permits. To an observer (and to yourself in the mirror), this can look like your lashes have grown longer and thicker, when in reality, you’re just seeing more of their actual potential length because they’re not breaking.
- Softer, More Flexible Lashes: Hydrated lashes are more flexible and may appear more lustrous.
The Myth (What Vaseline Cannot Do):
- Increase Follicle Activity: It does not contain any ingredient that signals the hair follicle to enter or extend the anagen (growth) phase.
- Add New Lashes: It will not stimulate the growth of new lash follicles where none exist.
- Permanently Change Genetics: Your maximum lash length, thickness, and curl are determined by your genetics. Vaseline cannot rewrite this code.
A 2014 study published in the Journal of the Society of Cosmetic Chemists evaluated various oils and treatments on eyelashes. While some ingredients showed minor effects on lash parameters, petroleum jelly (Vaseline) was not highlighted as a growth stimulant. Its primary role was recognized as an emollient and protectant. The perceived "growth" is a cosmetic effect of preservation, not creation.
The Right Way (and Wrong Way) to Apply Vaseline to Lashes
If your goal is to condition and protect your lashes to minimize breakage, here is the safe and effective method for using Vaseline:
- Start Clean: Ensure your eyelids and lashes are completely clean and free of makeup, especially old mascara. Use a gentle, oil-free makeup remover.
- Use the Right Tool:Never apply Vaseline directly from the jar with your fingers. This introduces bacteria and risks getting the product inside your eye. Instead, use a clean, disposable mascara wand, a cotton swab, or a clean fingertip only if you’ve scooped a tiny amount onto a tissue first.
- Minimal is Key: Dab the wand or swab into the Vaseline and wipe off the excess on the jar rim. You want a microscopic film, not a gloppy coating.
- Apply Carefully: Gently run the wand along your upper and lower lash lines, focusing on the base of the lashes where they emerge from the follicle. Avoid getting product on the actual lash shaft if your goal is follicle health, as heavy coating can weigh lashes down. A light touch at the root is sufficient.
- Leave It On: Apply this thin layer at night before bed. This allows the product to work without interference and prevents it from mixing with daytime mascara or getting into your eyes during the day.
- Morning Clean-Up: In the morning, gently wipe away any residual Vaseline with a damp, warm washcloth or cotton pad. You should not need to use harsh rubbing.
Critical Warnings and Precautions
- Avoid the Eye: Getting petroleum jelly in your eye can cause significant irritation, blurred vision, and even a risk of infection if bacteria from the jar is introduced. It is not sterile.
- Patch Test First: Apply a small amount to the skin behind your ear or on your inner arm. Wait 24 hours to check for allergic reactions (redness, itching, swelling).
- Not for Mascara Replacement: Do not use Vaseline as a mascara substitute. It will clump, smear, and provide no pigment or lengthening effect.
- Comedogenic Risk: While Vaseline itself is non-comedogenic (won’t clog pores) for most skin, applying it too close to the lash line on acne-prone skin could potentially trap oil and debris, leading to styes or folliculitis (inflammation of the hair follicle).
- Hygiene is Paramount: The jar is a breeding ground for bacteria. Never share your Vaseline, and always use a clean applicator to scoop product out.
Beyond the Blue Jar: Proven Alternatives for Lash Growth
If your primary goal is true growth stimulation, not just conditioning, you need to look for products with active ingredients that have some scientific backing. Here are the most effective categories:
1. Peptide-Infused Serums
Peptides are short chains of amino acids that act as signaling molecules. Specific peptides, like acetyl tetrapeptide-3 and myristoyl pentapeptide-17, are found in many lash serums. They are designed to support the keratin structure of the lash and may help extend the anagen phase. Look for serums from reputable brands that list their peptide complexes.
2. Bimatoprost (Prescription & OTC)
This is the gold standard and the only FDA-approved treatment for hypotrichosis (inadequate eyelashes). Latisse is the prescription brand. It works by prolonging the anagen phase and increasing the number of hairs in that phase. Results are significant and clinically proven, but it requires a doctor’s prescription and can have side effects like eye irritation, darkening of the iris, and darkening of the skin around the eyes. Some over-the-counter products use a lower-concentration version or similar prostaglandin analogs, but their efficacy is less studied.
3. Nourishing Natural Oils
While not growth stimulants, oils like castor oil, argan oil, and coconut oil are excellent conditioners. They are rich in fatty acids and vitamin E, which can penetrate the lash shaft to moisturize and strengthen, reducing breakage. The result is healthier, more resilient lashes that can grow to their full potential. They are a much better conditioning alternative to Vaseline due to their smaller molecular size and nutrient content.
4. Lash-Enhancing Mascaras & Primers
Many modern mascaras contain film-forming polymers and conditioning agents like panthenol (pro-vitamin B5) that coat lashes to make them appear instantly longer and fuller while providing care. Lash primers can be applied first to add volume and protect lashes from mascara.
What the Experts Say: Dermatologist and Ophthalmologist Insights
We spoke with the consensus in the dermatological and ophthalmological communities. The overwhelming professional opinion is clear:
"Vaseline is an occlusive, not an active treatment. It can help with dryness and may reduce lash breakage by keeping the shaft supple, which can create the appearance of longer lashes. However, it does not contain any ingredient that can biologically stimulate the hair follicle to produce a longer, thicker lash. For true growth stimulation, patients should look for products with proven active ingredients like peptides or, for significant results, prescription bimatoprost under the guidance of a doctor."
Dermatologists also emphasize the importance of overall health. Your lashes, like all hair, reflect your internal state. A diet rich in protein, biotin, iron, and vitamins (especially B vitamins and vitamin E) supports healthy hair growth. Managing stress and avoiding harsh rubbing or pulling on lashes (from aggressive makeup removal or eyelash curlers) is also critical. Furthermore, they warn that applying any product too close to the eye carries a risk of contact dermatitis or conjunctivitis if the product migrates.
Addressing Your Burning Questions
Q: How long does it take to see results from Vaseline on lashes?
A: If you’re hoping for growth, you won’t see it. If you’re using it for conditioning, you may notice lashes feel softer and less brittle within a week or two. The "appearance" of increased length due to reduced breakage might take a full lash cycle (6-8 weeks) to become noticeable, as you wait for new, undamaged lashes to grow in.
Q: Can Vaseline cause styes or eye infections?
A: Yes, it’s possible. If bacteria from your fingers or the contaminated jar is introduced into the oil gland at the base of an eyelash (a meibomian gland), it can cause a stye (hordeolum). Always use a clean applicator and avoid getting product in the eye.
Q: Is it better to use castor oil or Vaseline for lashes?
A: For conditioning, castor oil is generally preferred by beauty experts. It’s a triglyceride with a smaller molecular structure than petroleum jelly, allowing for better penetration to nourish the lash shaft. It also contains ricinoleic acid, which has anti-inflammatory properties. Vaseline sits on top and seals in moisture but doesn’t deliver nutrients.
Q: Should I use Vaseline if I have sensitive eyes or wear contacts?
A: Exercise extreme caution. The risk of product migrating into the eye and causing irritation or blurry vision is high. It’s not recommended for contact lens wearers or those with sensitive eyes. Opt for a lash serum specifically formulated and ophthalmologist-tested for the eye area.
The Verdict: A Final Word on Vaseline and Lash Growth
After examining the science, the biology, and the expert opinions, the answer to the question "can Vaseline make your eyelashes grow" is a definitive no. It is a powerful and effective occlusive moisturizer and protectant. Its value lies in preventing damage and dehydration, which can help your natural lashes achieve their genetically predetermined maximum length by reducing breakage. This conditioning effect can create a beautiful, healthier-looking lash line.
However, if your goal is to actively stimulate new growth, increase lash density, or significantly lengthen your lashes beyond their natural capacity, Vaseline is not the tool for the job. For that, you must turn to products with clinically-proven active ingredients like peptides or, for the most dramatic and regulated results, a prescription treatment like bimatoprost under medical supervision.
The most sustainable path to gorgeous lashes is a holistic one: gentle care, a nutrient-rich diet, smart product choices based on evidence, and a healthy dose of realism about your genetic potential. So, keep your Vaseline for its many other brilliant uses—chapped lips, dry cuticles, and protecting your skin—but look elsewhere for your lash growth aspirations. Your future, fluttery self will thank you for making an informed choice.
