The Story:

At only 0.05mm thick, eyelid skin is the thinnest and most vulnerable skin on the body.  It needs tender loving care to look its best as it is one of the first areas of the body to show signs of premature aging.  Lids and skin health (L.A.S.H.™) is an essential and growing focus within the skincare category.


L.A.S.H.™ Complex is a naturally derived blend of extracts proven to soothe the eye area.  This ophthalmologist developed and tested complex is designed to target the unique anatomy and function of the eyelid skin to optimize eyelid skin health.  L.A.S.H.™ Complex can be added to either treatment or makeup products that are created for consumers with sensitive eyes.  Eye sensitivity makes it uncomfortable to wear mascara and eyeliner.  Sometimes the wearing of eye makeup can exacerbate this sensitivity and lead to further issues such as crusting, puffiness and itching.  When these issues occur, doctors typically recommend that the patient stops wearing eye makeup until the symptoms go away.  By incorporating L.A.S.H.™ Complex into eye area treatment and makeup products, these symptoms can be avoided and there is no need to stop wearing makeup!

Technical Data:
Proven to Reduce Eye Inflammation and Sensitive Eye Symptoms

A 30-person panel (males and females, ages 21-75), who were clinically identified as suffering from sensitive eyes and had positive InflammaDry* test results, were given an eyelid primer containing 5% L.A.S.H.™ Complex and instructed to apply to upper and lower eyelid margins two times daily.  In two weeks, clinical observation showed that 90% of subjects had an overall improvement in eyelid margins with reduced scaling and redness, and 90% of subjects converted to negative InflammaDry test results.   Additionally, the majority of subjects found the product to be effective in reducing gritty and dry eye sensations.

* InflammaDry is a test that detects elevated levels of the inflammatory marker MMP-9, which is consistently elevated in the tears of patients with dry eye disease.

Antimicrobial Activity

L.A.S.H.™ Complex was in vitro tested for its antimicrobial activity against microorganisms known to negatively impact eyelid comfort.  Two assays were performed – an MIC and a Kill Rate test on P. acnes. S. aureus and S. epidermidis using AzaSite as a positive control.  These test results clearly show that the L.A.S.H.™ Complex has equivalent, and in some cases, superior efficacy to the prescription antibiotic AzaSite, which is commonly used to treat irritations of the eye.
