In Vivo Testing To Support The Growth And Volume Of Eyelashes

Eyelashes are a particularly prominent, natural facial attribute that most people are lucky enough to be born with.

Genetics, hair color, age, gender, and ethnic background all play a strong role in determining how prominent the eyelashes are.

Regardless of the density of natural eyelashes there are mechanisms which can improve the appearance of the lash cortex whether it is by lengthening, thickening, or darkening their appearance.

Cosmetic Eyelash Studies And Over The Counter Growth Support

Unlike many other beauty trends, with eyelashes the common consensus is “more is better.”

There are many different ways to make it appear that you have thicker, fuller, longer lashes, and there are drug and Over The Counter products for physically growing and retaining your lashes over a longer period of time.

Clinically Testing Eyelash Enhancement Products As A Focal Point

The eyelashes frame your eyes, which are the second most commonly focused on area when people meet (after the lips). When it comes to “holding a gaze,” the eyes have it, no contest.

As a result of the prominence of the eyes, eyelash enhancement is an effective way to highlight and draw more attention to one of your most beautiful assets.

Eyelash Retention and Eyelash Growth Studies

On average, most people will lose between 3-5 natural eyelashes per day. Like with hair, lashes go through three distinct phases of growth: Anagen, Catagen, and Telogen.

The complete cycle of eyelash growth generally takes between 3 and 11 months depending on the individual.

Utilizing techniques to reduce the fallout of natural lashes, they can grow longer and thicker and the overall quantity of lashes may also be improved. Together these factors can make for a fuller and more voluminous appearance.

Eyelash OTC Clinical Studies and Drug Implications

It is important to note that growth and retention are all considered to be part of the Over the Counter (OTC) drug realm. Both are both highly regarded and highly regulated claims, and mentioning these terms in your marketing materials can categorize your products as drugs in many markets around the world.

It is imperative that you use a Validated Claim Support FDA registered laboratory to substantiate your clinical claims, and when drug level claims are involved an even higher level of scrutiny is required.

The FDA can, has and will continue to issue warning letters for Eyelash Growth Claims that are unsubstantiated, and for products containing ingredients that have been previously classified as drugs.

Validated Claim Support is FDA Registered and Inspected, and we can handle your cosmetic and and/or drug related claim support needs.

Mascara Testing and Cosmetic Eyelash Claims

Mascara was invented in 1872 by French perfumer-entrepreneur Eugène Rimmel. His original lash plumping formula was simple and was composed of 2 ingredients: petroleum jelly and coal dust.

Cosmetic science has come a long way in the last 150 years, and mascara has become a billion dollar industry across the globe.

Differentiating mascara products from the competition involves well planned and executed clinical studies, designed to highlight unique product attributes including shine, color, length, volume and curl.

VCS has a number of novel photographic techniques to help make your mascara products stand out from the competition. Our proprietary clinical photography can help you bridge the gap between clinical science and consumer friendly marketing images.

Eyelash Extension Clinical Testing

Lash extensions are an immediate way to improve the overall visual presence of the lashes. Ranging from products you can buy at the drug store to professional salon level products, these enhancements are becoming more and more popular.

For lash extension products, claims regarding durability, duration, ease of application, volume and visual improvement can help market your brand.

VCS can custom tailor a consumer study to promote Eyelash Enhancement products.

Sample Eyelash Enhancement Claims:

Improves eyelash appearance
Eyelashes appear fuller
Helps retain eyelashes
Improves curl and visibility
Improves shine and reflectivity
Improves Eyelash Density by XX%
