You’re not alone if you want fuller, longer lashes. One study from 2014 found that 75% of women between the ages of 18 to 65 want darker, thicker eyelashes. And with eyelash extensions and fake lashes skyrocketing in popularity in recent years, it’s not hard to understand why. Lash serums promise to grow your lashes quicker to give you a fuller appearance, and many people swear it works. But if you’re pregnant, you may be wondering whether this is a product you need to discontinue using until after the baby is here.

How Lash Serums Actually Work

Lash serums may sound too good to be true. If we can grow thicker lashes, how come there’s no quick fix for thinning or balding hair? But the science behind lash serums is sound and consumers have found they do work to improve lashes.

Nouveau Lashes explains that lash serums use a variety of ingredients to make lashes grow faster. Lash serums usually are 1 of 3 types:

  1. Peptide-based
  2. Vitamin-based
  3. Prostaglandin-derived

Prostaglandin-derived ingredients encourage the lash follicle to enter the growth stage faster and for a longer period. Though lashes usually have a 6-week life cycle before shedding, this extends the time frame. That way, your eye retains more lashes at once, giving a fuller appearance.


Peptides similarly work by stimulating the growth of the hair follicle. Conversely, vitamin-based lash serums focus on providing nutrients to the hair to promote healthy, strong growth. Whereas the weaker and more brittle the lashes, the more easily they fall out and become sparse.

Some of the other common ingredients you’ll see in lash serums includes keratin, which is a natural protein in hair that is responsible for its strength and structure. Similarly, sodium hyaluronate, panthenol (vitamin B5), and botanical extracts all condition and moisturize lashes.

Use Of Lash Serums In Pregnancy

The problem with lash serums is that there’s limited research on their safety. Manufacturing guidelines and pharmaceutical / beauty standards vary depending on the country, so what’s deemed safe somewhere may not be elsewhere.


Romper spoke to several dermatologists to get to the bottom of whether lash serums are safe. In general, experts warn expecting women to avoid these serums until after birth. With many lash serums unregulated and untested, the effects on maternal and fetal health are unknown. So, a professional will tell you it’s better to err on the side of caution.

Skin & Eyes More Sensitive While Expecting

Even if lash serums aren’t detrimental to fetal health (which remains inconclusive), what’s known is that there’s a higher chance of experiencing irritation from a lash serum while pregnant since the eyes and skin are more sensitive. It’s normal to experience vision changes in pregnancy, largely due to hormonal fluctuations. You may become more sensitive to light and experience headaches and migraines. Your prescription can even temporarily change.


Likewise, hormonal changes also make your skin more sensitive. While some women are glowing in pregnancy, others find their skin is different than normal. It may be more sensitive and can exacerbate conditions like eczema.

Pregnancy Means Higher Chance Of Irritation

One of the well-known symptoms of lash serums is skin irritation. You may notice the skin on your eyelids and / or around your eyes becoming red, itchy, and even inflamed. This is usually only temporary but feel and look uncomfortable. Lash serums have also been known to cause temporary dry eye. Some women experience an increase in dry eye in pregnancy. Since it’s easier to become dehydrated while expecting (your body needs more fluids to support the growing baby), dry eye is more likely.

With your skin more sensitive in pregnancy, you’re at a higher risk of experiencing these common side effects from lash serum. The more you use it, the more you can expect to see irritation.

The Long-Term Risks Of Lash Serums

Skin irritation isn’t the only side effect you need to worry about. In rare instances, long-term health effects have been reported in people using lash serums regularly, pregnant or not. Given these risks and that the research on lash serums are limited, it’s even more reasons to avoid it until after pregnancy.

For example, some people have reported the darkening or their eyelid skin or even that the iris of their eye has changed color (it appears to be more common in brown eyes), WebMD explains. Some research has found lash serums can reduce volume in the eyelid, contributing to signs of aging.

Though rare, some people have reported allergic reactions to lash serums. Not all medications used in response to infections and reactions are safe in pregnancy, which makes it complicated to treat an allergic reaction when expecting.
