This is a common misunderstanding.
Eyelash serums do not contain hormones.

Hormones are chemical messengers that travel through the bloodstream and affect multiple systems in the body, such as metabolism, mood, and growth.
Using hormones in cosmetic products would neither be practical, cost effective, nor permitted under EU cosmetic regulations.

What is often confused with hormones are prostaglandin analogues. These are synthetic compounds that mimic the body’s naturally occurring prostaglandins.
They are not hormones and work locally where they are applied.

What are prostaglandin analogues

Prostaglandin analogues are synthetic substances that can influence the hair follicle growth cycle by extending the active growth phase.

How do they work

They act locally along the lash line and may contribute to longer and denser lashes over time by stimulating the hair follicles.

Do they affect the rest of the body

No. They work locally at the application site and are not transported systemically through the body in the same way as hormones.

Not all eyelash serums contain prostaglandin analogues. Many modern formulas are instead developed with peptides, vitamins, and conditioning ingredients that focus on lash quality and strength rather than rapid growth.

Claims about so called orbital fat loss occasionally circulate online. However, there is no established scientific evidence showing that cosmetic eyelash serums cause fat loss around the eyes.

Orbital fat loss is typically associated with:

natural aging

genetic factors

medical conditions

hormonal changes

Eyelash serums are applied superficially along the lash line and are designed to act locally. They do not affect underlying fat tissue or facial structure.

Some eyelash serums, particularly those containing higher concentrations of prostaglandin analogues, may in certain cases contribute to temporary pigmentation changes along the lash line.

However, this does not apply to all eyelash serums. The risk varies depending on:

formula

concentration

application technique

individual skin sensitivity

Correct application is essential. Over application or applying the serum outside the lash line can increase the risk of unwanted skin reactions.

Eyelash serums without prostaglandin analogues focus on:

strengthening the lash structure

reducing breakage

conditioning lashes over time

Common ingredients include peptides that help reinforce the lashes, panthenol and biotin that contribute to flexibility and care, as well as botanical extracts that condition the lash line.

These serums work in harmony with the lashes’ natural growth cycle and deliver more gradual and stable results.

Lenoites Eyelash Growth Serum is developed for those who want to care for and strengthen their lashes in a gentle and long term way.

Our serum is:

free from prostaglandin analogues

hormone free

dermatologically tested

suitable for sensitive skin

The formula is based on peptides, vitamin B5, biotin, and conditioning botanical extracts that help strengthen the lashes from root to tip and improve their resilience over time.

Many users experience:

• softer and healthier looking lashes within 1 to 4 weeks
• visible improvement in fullness and length after 4 to 6 weeks
• full results after approximately 8 to 12 weeks with consistent use

Results may vary depending on individual conditions and consistent application.

Do eyelash serums contain hormones

No. Eyelash serums do not contain hormones. Lenoites Eyelash Growth Serum is completely hormone free.

Does Lenoites Eyelash Growth Serum contain prostaglandin analogues

No. Our serum is entirely free from prostaglandin analogues and focuses on care and strength over time.

Can eyelash serums cause dark skin around the eyes

Some eyelash serums may do so, but since Lenoites Eyelash Growth Serum is prostaglandin free, it does not cause this when used as directed.

How long does it take to see results

Most users see gradual improvements within 4 to 6 weeks and full results after approximately 8 to 12 weeks.

How should the serum be applied

Apply a thin layer along the upper lash line on clean, dry skin. One dip is sufficient for both eyes. Using more product will not improve results.

Can I use the serum if I have sensitive eyes

Yes. The serum is developed for sensitive skin, but we always recommend performing a patch test before first use.

Can the serum be used during pregnancy or breastfeeding

Since the formula is free from prostaglandin analogues, it can be used. However, we always recommend consulting a healthcare professional if you are unsure.

Do I need to use the serum continuously

Yes. To maintain results, we recommend maintenance use after achieving your desired results, applying every third day after 12 weeks.
