Are Lash Serums Safe for Your Eyes?


Ever spot somebody with full, lush lashes and instantly wonder if they’re extensions or fake? Especially when ours seem to fall out every time we wash our face. Now thanks to serums, it’s possible to get longer-, shinier- and denser-looking lashes on your lash line.

But how safe are lash serums for your eyes? The scores of serums out there aren’t all created equally. Some are formulated with compounds that have lasting side effects, while others are dermatologically proven to improve lash quality and thickness using mild ingredients.


Some lash serum formulas have side effects that can cause blue or light-colored eyes to darken.

What Are the Different Types of Lash Serums?

Eyelash serums help to support better-looking lashes for women who experience thinning, age-related lash loss. You may also use them to simply enhance the lashes you already have. 

Lash serums use various ingredients and work by nourishing and fortifying your lashes. They typically fall into two categories based on their key ingredients:

  • Prostaglandin based
  • Vitamin and peptide formulated

Many lash serum products work to plump and hydrate your eyelashes with peptides and other ingredients and are generally thought of as safe. However, others using a synthetic version of prostaglandin, lipids derived from fatty acid found in our bodies and that have a hormone-like effect, have side effects that you may want to consider before purchasing, such as:

  • Unwanted hair growth on skin areas other than your lash line where the serum makes contact
  • Lowered eye pressure if the serum touches your eye
  • Permanently turning blue eyes brown or light eyes dark (though, so far, this side effect has only been observed in patients utilizing glaucoma drops)
  • Itchy, dry or red eyes
  • Puffy, weepy eyes
  • Clogged glands
  • Dark or red skin pigmentation changes along the lash line and eyelid
  • Rarely, retina swelling

Additionally, an ingredient in prostaglandin-based serums may cause discoloration of your soft contact lenses.

We Use Safe, Nourishing Ingredients in Our Lash Serum


As we get older, it becomes more challenging to grow lashes. Aligning with our holistic approach to age-related hair, scalp and lash care, our Superpower Lash Enhancing Serum uses ingredients that enrich your lashes from the inside out, including:

Myristoyl Pentapeptide-17

Better Not Younger incorporates a tailored blend of peptides including an essential amino acids called Myristoyl pentapeptide-17. This peptide helps to nourish and strengthen lashes for noticeably denser-looking lashes. 

Hyaluronic Acid

Hyaluronic acid is a sugar molecule made naturally by your body and is found in your skin and connective tissues. It is a large molecule that binds to water molecules and can hold more than 1,000 times its weight in water. Unfortunately, as we get older, our natural hyaluronic acid levels diminish, and our skin and lashes become dehydrated more easily.

Superpower Lash Enhancing Serum contains sodium hyaluronate, a form of hyaluronic acid known for its water retention properties. It helps condition and protect the brittle, damaged hair on our lash lines.

Pumpkin Seed Extract

Numerous plant-based extracts have garnered significant reputations for their beneficial fats and wellness perks; this includes pumpkin seed extract. Pumpkin seeds have been used for centuries for a wide range of health benefits.

Today, the phytosterols in pumpkin seed extract are thought to support healthier hair. It is also rich in vitamins A and C and amino acids to foster thicker healthier-looking lashes.
