Prostaglandins Vs. Peptides In Lash Growth Serums


Ocular hypotensive agents used for the treatment of glaucoma and hypertrichosis (a rare condition in which there is little or no hair growth on the head, including the brows, eyelashes, or other areas of the body where hair normally grows).

Prostaglandin analogs can have some unintended side effects.

Eye Redness & Irritation

The most common side effects after using a prostaglandin solution are an itching sensation in the eyes and/or eye redness.

Darkened Periorbital

The application of prostaglandin analogs to the upper eyelids appears to cause hyperpigmentation beyond the region of application.

This hyperpigmentation can extends onto the preseptal (inflammation of tissues) upper eyelid skin, and of the lower eyelids.


Meibomian gland dysfunction (MGD) refers to the condition where the glands are not secreting enough oil or the oil they secrete is of poor quality. Often, the oil gland openings get plugged up so that less oil comes out of the glands. The oil that does make it out of the glands can be granular (crusty) or otherwise unhealthy and can cause irritation. MGD can lead to altered tear film composition, ocular surface disease, ocular and eyelid discomfort, and evaporative dry eye.

The overall risk of eye color change with the use of prostaglandins is minimal.

Darkening of the Iris

Studies show that prostaglandin analogs can change eye color by increasing the size of the melanin granules in the eye. This means that blue eyes (and brown eyes) should not show any color change with the use prostaglandins. However, hazel eyes (and other eyes of mixed coloring) do show a risk of eye color change with the use of prostaglandins.

The overall risk of eye color change with the use of prostaglandins is minimal.
