The Most Important Lash Serum Ingredients | LashLuxury Blog

What is in your lash serum?

The market for eyelash growth serums is as diverse as the rainforest. 

On one hand you have Latisse, the prescription-only serum that was originally used as a drug to treat glaucoma.

On the other hand you have any one of the thousand products on Amazon.com claiming to work but listing such “active ingredients” such as Sodium Chloride (aka salt).

What ingredients do lashes need to grow longer and stronger? What ingredients help soothe the skin around my eyes to avoid irritation? What ingredients should I avoid at any cost???

We answer these questions and more in this quick but informative post.

The active ingredient in Latisse, one of the more well known lash serums, is called Bimatoprost and is a chemical in the prostaglandin family. Other prostaglandin analogs include Latanoprost and Dechloro Dihydroxy Difluoro Ethylcloprostenolamide. 

The name prostaglandin comes from the prostate gland, chosen when prostaglandin was first isolated from seminal fluid in 1935 by the Swedish physiologist Ulf von Euler.

While many popular lash serums use prostaglandin analogs, they can come with many side effects including:

  • Eyelid inflammation
  • A stinging or burning sensation around the eye
  • Discolouration or darkening of the iris

 It is not surprising then that Health Canada has put prostaglandins on their Ingredient Hot List and is why the LashLuxury daily lash serum does not contain any prostaglandins.

For non-regulated lash serums it is important that three types of ingredients are present: 

  1. Peptides (for strengthening lash follicles and boosting keratin and collagen production) 
  2. B Vitamins (to help moisturize each eyelash and transport important nutrients through the lash structure)
  3. Plant extracts (that are known to be anti-inflammatory and nourish your lashes)

The LashLuxury daily lash serum contains a powerful mix of all three important categories.

  • Peptides including Myristoyl Pentapeptide-17 and Acetyl Tetrapeptide-3 have amazing lash boosting effects. 
  • Panthenol (Provitamin B5) moisturizes lashes to avoid breakage and brittleness. 
  • Red Clover, Cucumber, Aloe and Castor oil provide essential nutrients to the lashes allowing them to reach their peak health.

Other ingredients that should be avoided at all cost are Parabens (often disguised by cosmetic brands as “Fragrance” on the ingredient list, Phthalates and DHT.
