Toplash Eyelash Growth Serum is a prostaglandin-free, hormone-free peptide serum for short, thin or brittle lashes. Draw one thin line along the upper lash line each night: peptides and pro-vitamin B5 condition the lashes from the root, so they look longer, fuller and darker. Some people see a difference from about 4 weeks; judge the full result after 12 weeks of nightly use.
Who it is for
- Short or sparse lashes that barely hold mascara.
- Lashes tired from extensions, clusters or lash lifts. The formula is oil-free, so it can be used with extensions.
- Brittle lashes that break from curling, waterproof mascara or rubbing off makeup.
- Sensitive eyes that react badly to serums with prostaglandin analogues.
Lashes that fall out in patches, or a lid that itches, swells or turns red, need a doctor rather than a serum.
Prostaglandin-free: why it matters
Many lash serums work with prostaglandin analogues such as isopropyl cloprostenate. In its 2026 opinion, the EU Scientific Committee on Consumer Safety (SCCS) concluded that three of these ingredients cannot be considered safe in cosmetic lash and brow products. Toplash relies on peptides and pro-vitamin B5 instead: there is no prostaglandin analogue and no hormone in the bottle.
What's inside
Two peptides, Myristoyl Pentapeptide-17 and Biotinoyl Tripeptide-1, with panthenol (pro-vitamin B5), a conditioning wheat protein and extracts of centella, green tea, licorice, chamomile and rosemary. The full INCI list is under Ingredients.
Lash serum or brow serum?
This is the same 3 ml formula as Toplash Lash & Brow Serum, presented for lashes. One bottle lasts about 2–3 months of nightly use on the upper lash line, and you can use it on your brows as well.

The Science of Growth
WEEKS 1–3
NIGHTLY HABIT
One line along the upper lash line each night. Peptides and panthenol condition the lashes, so they feel softer and break less when you curl them.
WEEKS 4–8
FIRST CHANGES
Lashes start to look longer and hold mascara better. Take a photo in the same light to compare with day one.
WEEK 12
FULLER-LOOKING LASHES
Lashes look longer, fuller and darker. Keep the look with 2–3 applications a week.
WHAT'S INSIDE
Peptides instead of prostaglandins
BIO-PEPTIDE
Myristoyl Pentapeptide-17
A signal peptide widely used in lash serums to help lashes look longer and stronger.
BIOTIN PEPTIDE
Biotinoyl Tripeptide-1
Biotin bound to a peptide. Conditions the lashes at the root.
PRO-VITAMIN B5
Panthenol
Holds moisture in the lash, so lashes are less brittle and break less.
Eyelash serum questions
How do I use an eyelash growth serum?
Once a day, in the evening, on clean and dry lids. Wipe the excess off the brush and draw one thin line along the base of the upper lashes, like eyeliner. One dip is enough for both eyes. Let it dry for 1–2 minutes before makeup or bed.
When will I see results?
Lashes grow in cycles, so the serum needs time. Some people notice a difference from about 4 weeks. Judge the full result after 12 weeks of nightly use, comparing before and after photos taken in the same light.
Does an eyelash serum actually work?
A peptide serum does not work like prescription lash treatments. It conditions the lashes you have, so they look longer and fuller and break less. Results vary from person to person, and they show only with daily use over several weeks.
Can I use it with lash extensions or clusters?
Yes. The formula is oil-free, so it can be used with lash extensions, clusters and strip lashes. Apply it to the lash line at the base of your natural lashes.
Can I use it if I wear contact lenses?
Yes. Take your lenses out before applying the serum and put them back in once it has fully dried. If your eyes water or sting, rinse with water and pause use.
Is it safe for sensitive eyes?
The formula has no prostaglandin analogues, no hormones and no oils. Before the first use, test a small amount behind the ear for 24 hours, and stop if the skin gets red or itchy. If you are pregnant or breastfeeding, ask your doctor first.
What happens if I stop using it?
Lashes gradually return to how they looked before. To keep the result, apply the serum 2–3 times a week once you are happy with your lashes.
