Eyelash growth serums promise longer, thicker, and darker lashes, offering an alluring boost to your natural beauty. However, board-certified dermatologist Dr. Sam Ellis shares an eye-opening perspective on why she personally avoids most lash growth serums, especially those containing a specific type of ingredient called prostaglandin analogs. Here’s what you should know before reaching for that serum.

What Are Prostaglandin Analogs and How Do They Work?

Prostaglandin analogs are the active ingredients found in many popular eyelash serums. They were originally discovered by ophthalmologists treating glaucoma, a condition characterized by increased pressure inside the eye. Patients using glaucoma eye drops containing prostaglandin analogs noticed an unexpected side effect: longer, thicker, and darker eyelashes.

How Prostaglandin Analogs Enhance Eyelash Growth

• Extended Growth Phase: Hair follicles, including eyelashes, cycle through three phases—growth (anagen), transition (catagen), and rest (telogen). Prostaglandin analogs work by lengthening the anagen phase, so lashes grow longer for a longer time.
• Increased Thickness: These ingredients enlarge the bulb—the base of each hair—resulting in thicker lashes.
• Darker Lashes: Prostaglandin analogs stimulate melanin production, making lashes appear darker and more prominent.
• More Visible Hairs: Because more lashes are simultaneously in the growth phase, your lashes don’t increase in number but look fuller.

The Hidden Risk: Prostaglandin Associated Periorbitopathy

While prostaglandin analogs are effective, they come with risks. Dr. Ellis highlights a serious condition called Prostaglandin Associated Periorbitopathy (PAP). This adverse effect is linked to prolonged use of lash serums containing prostaglandin analogs.

Symptoms and Effects of PAP

• Upper Eyelid Ptosis: Drooping of the upper eyelid, which can interfere with your field of vision.
• Fat Atrophy: Loss or shrinkage of the fat around the eyes, causing a sunken, hollow appearance.
• Prominent Eyelid Creases: Changes in eyelid structure making the crease more noticeable.
• Darkened Skin Around Eyes: Increased melanin and blood vessel growth make eyelids appear darker and veiny, potentially worsening dark circles.
• Iris Pigmentation Changes: Especially in blue or green eyes, the colored part (iris) may darken permanently to brown.

Dr. Ellis presents compelling images of patients using glaucoma eye drops containing prostaglandin analogs, clearly showing the visible tissue changes affecting both aesthetics and potentially vision.

Why Dr. Ellis Chooses to Avoid Prostaglandin-Containing Lash Serums

Despite the alluring benefits, Dr. Ellis explains that the side effects are inevitable with use—it's not a question of if, but when. Since everyone’s anatomy is different, the severity varies, but for those with:

• Deep-set eyes
• Minimal fat around the eyes
• Naturally pigmented and visible blood vessels

the risk outweighs the reward. For her personally, adverse changes were unacceptable, leading her to discontinue prostaglandin analog lash serums.

Is Prostaglandin Associated Periorbitopathy Reversible?

Good news: many of the side effects caused by prostaglandin analogs can reverse once you stop using the product. Within 4 to 6 weeks of discontinuing usage, significant improvements occur. However, reversal is not guaranteed in every case and may depend on individual anatomy and duration of use.

What Are Safer Alternatives for Enhancing Eyelash Appearance?

If you want to avoid the risks tied to prostaglandin analogs, consider gentler options such as:

• Nourishing conditioners and serums without prostaglandin analogs
• Products that focus on moisturizing and strengthening lash hairs
• Quality hair growth treatments formulated with safer ingredients

These promote lash health without the dangerous side effects associated with prostaglandin analogs.

Final Thoughts

While eyelash growth serums containing prostaglandin analogs are effective at enhancing lashes, they come with notable risks that can affect both the appearance and function of your eyes. If you’re considering these products, it’s crucial to weigh the benefits against potential side effects such as eyelid drooping, fat loss, and pigmentation changes.
