The Short Answer
Do not treat any lash serum as automatically pregnancy-safe. The LATISSE label says there are no adequate and well-controlled studies in pregnant women. For three cosmetic prostaglandin analogues, the SCCS found important safety data gaps. A prostaglandin-free label does not prove another formula is safe. Ask your obstetric clinician or prescriber before use.

Why Prostaglandin Lash Serums Are a Concern During Pregnancy
Some lash serums list prostaglandin analogues. The evidence must stay ingredient-specific: bimatoprost is not IPCP, and neither is DDDE. Findings from one ingredient or finished product should not be copied onto another.
The LATISSE prescribing label says there are no adequate and well-controlled studies in pregnant women. It says LATISSE should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. That statement applies to prescription bimatoprost.
For cosmetic analogues, The SCCS concluded in 2026 that it could not consider IPCP, MDN, or DDDE safe for this cosmetic use. The committee said the substances had potent pharmacological activity and that acceptable reproductive and developmental toxicity data were missing. That conclusion does not provide a product-specific event rate or prove that all analogues are identical.
We found no direct pregnancy study of the cosmetic lash serums listed below. Ask your obstetric clinician or prescriber to review the exact current formula rather than relying on a category label or this guide alone.
Labels That Need Clinician Review
These dated labels listed an analogue when reviewed. Formula labels can change:
- GrandeLASH-MD (contains isopropyl cloprostenate)
- NeuLash (contains isopropyl cloprostenate)
- RapidLash (contains isopropyl cloprostenate)
- Latisse (contains bimatoprost, prescription)
- RevitaLash (reviewed label listed DDDE)

Name endings are not a complete or reliable rule. Check exact names such as bimatoprost, isopropyl cloprostenate, cloprostenol isopropyl ester, MDN, and DDDE, then confirm the full current label with your clinician. Our ingredient checker only screens for a bounded list; it does not assess pregnancy safety.
Does Prostaglandin-Free Mean Pregnancy-Safe?
No. A prostaglandin-free label does not prove a peptide, botanical, or conditioning serum is safe during pregnancy or breastfeeding. It only means the covered analogue names were not found on the dated label check. Finished formulas can contain many other ingredients, and direct pregnancy data are sparse.
What A Label Screen Can Tell You
It can find names. It cannot clear a formula for pregnancy or breastfeeding.
Peptide-Based Formulas
Peptides are small chains of amino acids. Small human studies have tested finished serums containing several ingredients, but neither used a look-alike control serum and neither isolated one peptide. We found no controlled human study showing that myristoyl pentapeptide-17 alone grows lashes. We also found no direct pregnancy or breastfeeding study that clears peptide lash serums as a category.
Botanical Formulas
"Plant-based" describes ingredient origin, not pregnancy safety. Red clover, pea sprout, mung bean, preservatives, solvents, and other ingredients must be considered as part of the exact finished formula. We found no evidence that clears all botanical lash serums for pregnancy or breastfeeding.
Conditioning Serums
Conditioning formulas may list panthenol, oils, or hyaluronic acid. These labels do not prove a finished product will prevent breakage, avoid irritation, or be appropriate during pregnancy. Natural oils can also irritate some users or get into the eye.
The practical step: bring the current full ingredient list to your obstetric clinician or prescriber. Ask about the exact product, how you plan to use it, and any eye or skin condition you have.
For ranked options in these categories, see our guides to prostaglandin-free lash serums and the best peptide lash serums.
What About Breastfeeding?
The short version: direct lactation data are limited, so do not assume a topical lash serum is cleared because the amount applied is small.
The LATISSE label says: It is not known whether topical LATISSE use can produce detectable bimatoprost in human milk. It also reports animal data at a high intravenous dose, which should not be treated as a direct estimate for cosmetic use.
We found no direct study measuring transfer from a cosmetic lash serum into human milk. We also found no category-wide lactation study that proves peptide or botanical lash serums safe.

How to Grow Eyelashes Naturally During Pregnancy
If you choose to skip serums, simple handling habits may help you avoid pulling or rubbing lashes. They do not guarantee growth, prevent shedding, or replace medical care.
Lower-Complexity Habits
Low-complexity habits to discuss with your clinician.
Castor oil and coconut oil. We found no clinical evidence that castor oil makes lashes grow longer. Oils can get into the eye or irritate the skin, so "natural" does not mean automatically appropriate during pregnancy. For more context, see castor oil vs lash serum.
Do not add supplements for lashes on your own. Take prenatal vitamins and other supplements only in the doses your clinician recommends. More is not always better, and a lash-growth effect is not established.
Handle lashes gently. Avoid pulling or rubbing, and remove makeup without tugging. These habits reduce mechanical stress but do not guarantee that lashes will not shed.
Hair changes vary. Pregnancy and postpartum changes can affect hair, but this guide does not establish a lash timeline. Ask a clinician about sudden, patchy, painful, or persistent lash loss.
Frequently Asked Questions
Can I use GrandeLASH while pregnant?
The dated GrandeLASH-MD label we reviewed lists IPCP. The SCCS could not consider IPCP safe for this cosmetic use and cited missing acceptable reproductive and developmental toxicity data. That does not establish a product-specific event rate. Ask your obstetric clinician before using or stopping the product. See our GrandeLASH-MD review for the label and source links.
Is RapidLash safe during pregnancy?
The dated RapidLash label we reviewed lists IPCP. Direct pregnancy evidence for this finished product is limited, and a different prostaglandin-free product is not automatically cleared. Ask your obstetric clinician to review the current full label. See our RapidLash review for ingredient details.
Is RevitaLash pregnancy safe?
We cannot label the finished formula pregnancy-safe. The dated RevitaLash label we reviewed lists DDDE, one of the analogues in the 2026 SCCS opinion. Formula labels can change. Ask your obstetric clinician to review the package you have. Our RevitaLash review has the label details.
Which eyelash serum is pregnancy safe?
We found no category-wide evidence that clears a cosmetic lash serum for pregnancy. A prostaglandin-free label is useful for exact-name screening, but it does not prove a peptide, botanical, or conditioning formula safe. Ask your obstetric clinician to review the current full ingredient list.
Do pregnancy hormones affect eyelash growth?
Pregnancy and postpartum hair changes vary, and we did not find evidence that supports a universal eyelash timeline. Ask a clinician about sudden, patchy, painful, or persistent lash loss.
When can I start using lash serum after pregnancy?
Do not use this page to choose a restart date. The LATISSE label says it is not known whether topical use can produce detectable bimatoprost in human milk, and we found no direct cosmetic-serum transfer study. Ask your obstetric clinician, pediatric clinician, or prescriber to review the exact product and your circumstances.
