Hormone-Free Lash Serum vs Prostaglandin: What's the Difference?
Share
A hormone-free lash serum conditions lashes with ingredients such as peptides and hydrating agents, while a prostaglandin lash serum extends the hair's growth phase; that difference determines how quickly your client sees results and which side effects she may experience.
More and more clients ask about lash serums in the salon, and many have already read about the risks. The first question to answer is which type of serum suits her. Marie-José carries both types in the lash serum collection: a prostaglandin serum and a hormone-free serum. Below you'll find how they differ, so you can make a well-founded choice for every client.
What is the difference between a hormone-free lash serum and a prostaglandin serum?
Prostaglandin lash serum: extends the growth phase
Prostaglandin analogues are substances that originally come from the medical world. They extend the growth phase of the lash hair, so lashes keep growing for longer before they fall out. The effect is often visible quickly: lashes look longer and darker.
This mechanism can cause side effects. For some clients the risk is acceptable, for others it isn't. For sensitive eyes or thin skin around the eye, a prostaglandin serum is often too intense.
Possible side effects of prostaglandin
- Redness and itching around the eye
- Discolouration of the skin around the eye
- With long-term use: a change in iris pigmentation
Discuss these side effects with your client before she starts. If redness or irritation develops, she stops using the serum. If symptoms persist, refer her to her GP.
Hormone-free lash serum: conditions instead of forcing
A hormone-free lash serum contains no prostaglandin analogues and does not interfere with the growth cycle. It conditions lashes and brows with ingredients such as peptides, vitamins and hydrating agents. The result builds up gradually: lashes that look fuller and healthier.
So the difference lies not only in the ingredient list, but above all in how the serum works. That determines how quickly your client sees results and which risks she takes.
Which Marie-José lash serums are hormone-free?
Not all Marie-José lash serums are hormone-free. The range deliberately includes both types, so you have a suitable serum for every client.
Gentle Lash & Brow Serum (Multi-Peptide): hormone-free
The Multi-Peptide Lash & Brow Serum is Marie-José's hormone-free serum. It contains the peptides Biotinoyl Tripeptide-1 and Acetyl Tetrapeptide-3, together with panthenol, sodium hyaluronate and extracts of ginseng, mulberry and red clover. It is free from prostaglandins and fragrance, dermatologically tested and also suitable for sensitive eyes.
- For lashes and brows
- Results: with daily use, most users assess the result after 8 to 12 weeks
- Contents: 3 ml, enough for around three months of daily use
- Maintenance: after the first period, two to three times a week is enough
If your client stops completely, her lashes gradually return to their natural state.
Aphro Celina Lash & Brow Serum: with prostaglandin
The Aphro Celina Lash & Brow Serum is not hormone-free. It contains Isopropyl Cloprostenate, a prostaglandin analogue, and is aimed at maximum lash growth. If a client specifically wants a hormone-free product, the Multi-Peptide serum is the right choice.
Which serum suits which client?
Recommend the Multi-Peptide serum to clients with sensitive eyes or a preference for a gentle formula. If your client wants maximum lash growth and accepts the possible side effects of prostaglandin, Aphro Celina is an option. How to make that choice per client and standardise it within your team is covered in Aphro Celina or hormone-free serum: which do you recommend?
Ask two questions during the consultation: has she used a lash serum before, and do her eyes react quickly to products? With those answers you usually know straight away which type of serum fits. Record the choice in the client file so every colleague gives the same advice.
How to use the Multi-Peptide serum
Apply the serum once a day, preferably in the evening, as a thin line along the upper lash line on clean, dry skin. If serum gets into the eye, rinse immediately with water.
Combining lash serum with henna or hybrid brow tint
If you also work with henna brow tint or hybrid brow tint, the condition of the skin around the eyes and brows matters. A conditioning serum without prostaglandin puts no extra strain on that skin. Because the Multi-Peptide serum is also made for brows, it works well as home care after a brow treatment.
Frequently asked questions about hormone-free lash serum
What is prostaglandin in a lash serum?
A prostaglandin analogue is a substance that extends the growth phase of lashes, so they keep growing for longer than normal. In ingredient lists you'll see names such as Isopropyl Cloprostenate.
Is a hormone-free lash serum less effective?
It works differently. A hormone-free serum conditions the lashes and the result builds up gradually, rather than forcing growth. With the Multi-Peptide serum, most users assess the result after 8 to 12 weeks.
Can a prostaglandin lash serum cause side effects?
Yes. Possible side effects include redness, itching and discolouration of the skin around the eye, and with long-term use a change in iris pigmentation.
Are all Marie-José lash serums hormone-free?
No. The Multi-Peptide Lash & Brow Serum is hormone-free. Aphro Celina contains Isopropyl Cloprostenate, a prostaglandin analogue.
Can the hormone-free serum also be used on brows?
Yes. The Multi-Peptide serum is made for both lashes and brows. A 3 ml bottle lasts around three months of daily use.
Are Marie-José lash serums suitable for salons?
Yes. You can sell the serums in your salon and give them to your client after a treatment for use at home.
