Is a Solution for:
Eyelashes & Brows

It was Frieda Pinto's eyelashes that drew me towards an ad for L'Oreal's New Lash Boosting Serum. They were thick and woolly, like shagpile. The Slumdog Millionaire star looked as if her lids were too heavy to open, let alone that she would ever bat those lashes. L'Oreal's message was far subtle. Talk about lashing out at Bollywood. I had to know more.

The first thing that is a bit confusing is that Boosting Serum seems to be called Renewal in the UK. Although the Boosting Serum can be bought alone for $14.99, it also comes in a kit with a "top coat" and a "primer". In addition, L'Oreal recommends using it with its Double Extend Lash Boosting Mascara. No wonder Frieda looks a little weighed down.

L'Oreal isn't quite marketing Lash Boosting Serum as an eyelash growth product. It doesn't boast an eyelash growth stimulating ingredient such as the prostaglandins of Lilash or Revitalash. Nor does it come with the fashionable peptides and botanicals of the non-prostaglandin alternatives like Hydropeptide. L'Oreal says it will prevent eyelashes from falling out when removing makeup. However, it does have a handful of actives that typically condition hair and may help it grow.

The closest thing to an active for eyelashes is panthenol, which when it penetrates into lower skin layers, is absorbed into skin cells and processed into pantothenic acid (commonly known as vitamin B5). Madecassoside is gotu kola, a plant used in Chinese medicine. It is an anti-inflammatory, but I haven't found much that associates it with hair growth. There are useful amino acids including arginine which, according a Japanese study, can protect the hair from the effects of chemical coloring, even bleaching. So it might be useful against all those pigments in mascara.

I am surprised to see sodium hydroxide. This is, however, a known irritant. Studies by the National Institute for Occupation Safety and Health found that this ingredient causes “Irritation eyes, skin, mucous membrane; pneumonitis; eye, skin burns; temporary loss of hair” and recommends that consumers prevent skin and eye contact.

Ingredients in Serum:

Aqua (Water), Alcohol Denat, Glycerin, Hydroxyethylcellulose, Phenoxyethanol, Panthenol, Polysorbate 21, Madecassoside, Acrylamides/Sodium Acryloyldimethyltaurate Copolymer, Methylparaben, Octyldodecanol, Isohexadecane, Sodium Hyaluaronate, Arginine, Serine, Citric Acid, Glutamic Acid, Polysorbate 80, Sodium Hydroxide, 2 Oleamido 1,3 Octadecanediol.

    I have been using this producet for the past two years. My haridreser has been telling me for the past year and a half that my hair was thinning. Now I'm seeing a Dermatoligist to determine why my hair is disappearing. It's not falling out in clumps, just a patch here and there. I've stopped using this product. I hope that it is not the cause of my hair thinning.

    I began using this product last week and saw a change almost instantly! I've not experienced burning or irritation and I am sure that is a most unpleasant side effect, but I'm VERY pleased with the results!

    I have been using it and fortunately I have not experienced any side effects. I also notice that my lashes are longer, thicker. Even my friends start noticing it too..

    I started using the product a couple weeks ago, and I had one eye with shorter eyelashes than the other. When applying I had a tiny tad irritation, but its because I dabbed it by mistake in my eye.

    After 3 or so applications, I have seen results. my eyelashes are indeed longer. They arent fuller, but they are longer indeed. Now my eyelashes on both eyes equal in length.

    I hope this isn't temporary. That would be unfortunate.
