If you’re lucky enough to have been blessed with long, full, and dark eyelashes, you should be grateful. Many people will do anything to achieve this look — including using false lashes, eyelash extensions, mascara, and new rave of the moment far — OTC eyelash growth serums.

Over-the-counter eyelash growth serums are cosmetic products that are known to make eyelashes longer and fuller in a few weeks. But they’re not without pitfalls, as you will soon find.

Why Are Eyelash Growth Serums So Popular?

The global market for eyelash growth serums has boomed so much that it’s expected to skyrocket from $752 million in 2020 to $1.3 billion by 2031, per Business Wire. As of now, there are at least 1.5 billion TikTok views for searches relating to “the best lash serum.”

We believe that people are wild about this product because of how easy it is to apply. They only need to apply a few swipes of the serum every day to achieve the desired effect.

What Do Eyelash Growth Serums Contain?

Eyelash growth serums yield positive results because they’re packed full of Vitamins E and C, growth peptides, and biotin. According to board-certified dermatologist Quynh-Giao Sartor, these ingredients help the lashes look healthier by providing them with nourishment (via Verywell Health).

No matter the type of eyelash growth serum you purchase in the market, most of them have one aim — to keep the eyelash hairs as lengthy and thick as possible.

Here Comes the Risks

If you thought that eyelash growth serums were magical products with zero tolerance for side effects, we’re sorry to burst your bubble. Like every other quick fix, these serums have their own fair share of risks.

Dermatologist and dermatopathologist Brendan Camp told Verywell Health, “Eyelash growth serums of any type have the potential to cause skin irritation in the form of redness, swelling, itching, and scaling.” That’s especially true when they aren’t used as directed.

It Can Get Worse

Unfortunately, that’s not all there is to the risks associated with using eyelash growth serums. Some serums contain prostaglandin analogs (PGAs) that may cause more significant damage.

According to Sartor, this ingredient may melt the fat around your eyes, a phenomenon called “periorbital volume loss” in the medical world. It can increase pigmentation in the affected area and make your iris and eyelid skin darker than normal, leading to sunken eyes.

What Are PGAs?

Prostaglandin analogs are compounds that were formulated to treat glaucoma. It was later discovered that many glaucoma patients who used these compounds had significantly longer eyelashes than before. After more research was conducted and with approval from the FDA, PGAs started featuring in many eyelash growth serums because of their amazing ability to stimulate eyelash growth and make them look more appealing.

Sadly, PGAs have been said to increase the risk of “prostaglandin-associated periorbitopathy,” a condition that makes the eyelids and orbital region wrinkled, darker, and thinner, according to a study from Aesthetic Surgery Journal.

How Do You Detect PGAs in Eyelash Growth Serums?

Many over-the-counter and prescription eyelash growth serums contain PGAs, which can be verified from their ingredient listings. Popular ones include Rodan and Fields R+F Lash Boost, Babe Lash Essential Serum, Revitalash Advanced Eyelash Conditioner, UKLASH Eyelash Serum, GrandeLASH-MD Lash Enhancing Serum, and NeuLASH Lash Enhancing Serum.

Note that even eyelash serums without PGAs still carry potential health risks due to fragrances, preservatives, wax, oils, silicone, etc.

Generally, these products are considered safe to use, but as Camp told Verywell Health, “The use of any skin care product carries the risk of irritant or allergic contact dermatitis.” Camp added, “Eyelash serums without PGAs may not have risks like hyperpigmentation of fat atrophy.”

Generally, the lighter your iris, the more prone they are to darkening. However, we advise that you seek professional guidance from your dermatologist, ophthalmologist/oculoplastics, or plastic surgeon. They’re in the best position to give you personalized advice.

Camp told Verywell Health that green tea contains antioxidants in good measure, which is amazing because it can keep your lash hairs safe from free oxygen radicals that cause oxidative stress. Oxidative stress can impede hair growth.
