What is the role of the eyelash? Function, usefulness and secrets

We make them up, we curl them, we lengthen them, we enhance them with false eyelashes... but do we really know what eyelashes are for?
These small, discreet hairs at the edge of our eyelids have a much more important role than we think. Beyond aesthetics, they provide a real protective function for our eyes.

In this article, we dive into the role of natural eyelashes , and discover why it's important to take care of them, especially when using false eyelashes .

👁️‍🗨️ 1. The main role of eyelashes: to protect the eye

Eyelashes aren't just there to beautify your eyes. Their main mission is to protect the eye , an extremely fragile organ.

🛡️ Natural barrier against external aggressions

Eyelashes act as a dust bumper . As soon as a particle (dust, sand, pollen, etc.) approaches the eye, the eyelashes detect it and repel it , often by triggering a reflex blink .

💨 Filter against air and wind

By slowing the flow of air reaching the surface of the eye, eyelashes help keep the eye hydrated . Less air = less evaporation of natural moisture.

🐜 Immediate contact detection

Eyelashes are very sensitive : at the slightest contact (insect, grain of dust), they trigger a reflex to close the eyelids to protect the eye.

🔄 2. The life cycle of eyelashes: natural regeneration

Like hair, eyelashes follow a natural life cycle made up of 3 phases:

Anagen (growth) – lasts 30 to 45 days
Catagen (transition) – 2 to 3 weeks
Telogen (falling out) – the eyelash falls out to make way for a new one

💡 It's normal to lose 2 to 5 eyelashes per day . False eyelashes or mascara aren't necessarily responsible for this, as long as they're used with care.

🌱 3. Eyelashes and beauty: a powerful aesthetic asset

If their biological role is protective, their social and aesthetic role is just as powerful. Long, well-curled eyelashes enlarge the eyes, make them more expressive and more seductive .

This is why for centuries, in all cultures, eyelashes have been:

made up (kohl, mascara, etc.)
dyed or curled
augmented with false eyelashes or extensions

👑 Today, false eyelashes have become a must-have in modern beauty, allowing you to intensify your look in the blink of an eye... without waiting weeks for natural eyelashes to grow.

💖 4. False eyelashes and natural eyelashes: a healthy coexistence, if used well

At Faux Cils Pro , we insist on one point:
False eyelashes do not damage natural eyelashes if you apply and remove them correctly.

✅ Our advice for preserving the protective role of your eyelashes:

Use a soft, latex-free glue
Remove your false eyelashes gently with a two-phase makeup remover or oil
Nourish your natural lashes with castor oil or a strengthening serum
Alternate days with and without false eyelashes to let your lashes breathe

👉 For this, our false eyelashes are light, flexible, and reusable up to 25 times : perfect for an intense look without damaging your natural eyelashes.

👁️‍🗨️ 5. What if your eyelashes are short or fragile?

Do you have thin, sparse, or damaged eyelashes? This is where false eyelashes become a perfect solution :

✔️ They do not alter your natural cycle
✔️ They save you from rubbing your eyelashes with waterproof mascara
✔️ They allow you to have an intense look while letting your eyelashes rest

At Faux Cils Pro , we also offer false eyelashes for sensitive eyes , suitable for all eye shapes and easy to apply.

🔬 6. Eyelashes under the eye of science: an ingenious natural design

Did you know that the ideal length of a human eyelash is about one-third the width of the eye ? This is no coincidence. According to scientific studies (such as the one published in The Journal of the Royal Society Interface ), this proportion allows for:

✅ To reduce the speed of air reaching the ocular surface
✅ To optimize the natural humidity of the eyes
✅ Filter dust, allergens and micro-particles

🔎 In other words, eyelashes act as a passive, intelligent barrier , designed to maintain an optimal microclimate around the eye. Impressive, right?

🧖‍♀️ 7. How to care for your eyelashes on a daily basis (natural or not)

Even if you wear false eyelashes regularly, your natural lashes deserve just as much attention as your hair . Here's a simple and effective routine to keep your lashes strong, shiny, and resilient:

💧 Clean without harming

✔️ Always remove your eye makeup with a gentle makeup remover , preferably two-phase or natural oil-based.
✔️ Use reusable cotton pads or cotton swabs , and avoid rubbing too hard.

💆‍♀️ Massage the lash line

This stimulates blood circulation and promotes faster, thicker regrowth. Just a few seconds a day is all it takes.

🌿 Nourish deeply

Use vegetable oils (castor, sweet almond, argan, jojoba) or a specific serum to strengthen your natural eyelashes.

🚫 8. What damages your eyelashes (and how to avoid it)

Even though eyelashes are designed to renew themselves naturally, certain actions or products can weaken their life cycle :

🔻 Repeated waterproof mascara : difficult to remove, it promotes breakage.
🔻 Incorrectly applied or too frequent eyelash extensions : they pull on the root.
🔻 Excessive rubbing of the eyes (especially when removing makeup).
🔻 Eyelash curlers misused : never apply to makeup-covered eyelashes!

💡 Gentle solution? Wear quality reusable false eyelashes , like those from Faux Cils Pro , for an intense look without mascara or harsh extensions .

🧬 9. Eyelashes, health and deficiencies: what your eyelashes can reveal

Eyelashes that fall out abnormally , become brittle or no longer grow back can sometimes be a sign of an internal imbalance :

🔸 Iron, zinc or biotin deficiency
🔸 Hormonal or thyroid problems
🔸 Allergic reactions (cosmetics, environmental)
🔸 Stress or chronic fatigue

🩺 If your eyelashes are falling out in significant quantities for no obvious reason, do not hesitate to consult a dermatologist .

🌟 10. False eyelashes & eyes: more than a beauty asset, a confidence booster

The eyes are the first language of the face . Long, well-defined eyelashes can completely transform a person's expression and boost their self-confidence .

At Faux Cils Pro , we have seen clients tell us that they feel:

More elegant , even without makeup

And all this, thanks to a well-chosen pair of false eyelashes .
