Mascara performance depends on.

• Lash fiber thickness
• Eye socket anatomy
• Eyelid fold structure
• Brush geometry
• Formula chemistry (wax vs polymer vs film former)

If you ignore the biology and mechanics, your mascara will smudge, clump, or disappear.

This article explains what actually works and why.

What functioned mascara? 

• Mascara enhances eye depth and definition. 
• Create an eye opening effect 
• enhance adaptability in addition to other types of eye makeup 
• A quick and easy way to improve your natural beauty that saves time 
• Boost self assurance (by improving eye quality)

The Science Behind the Performance of Mascara 

1.  Biology of Lash 

Distinctive human eyelashes are: 

• Diameter
• Direction for growth 
• Retention of curls 
• Exposure to oil 

Because oil and moisture relax the structure of keratin, straight lashes lose curl more quickly.

2.  Physics of Brush 

Design Brushes for mascara work by: 

• Fibers being separated 
• putting pigment down 
• Lifting by mechanical 

means Brushes with curves follow the shape of the orbital bone. 

Rubber combs reduce clumping while distributing less product. 

Brushes with dense bristles have more volume but cause overload.

3. Formula Chemistry

• for volume, heavier

Use Wax based mascaras  

• For hold curl longer

use Polymer film mascaras  

• form water resistant tubes

use Tubing mascaras 

Guide to Mascara Based on the Shape of the Eye 

• Oyster Eyes Structure(Almond)

Eye with a balanced width and a visible crease 

The classic curved fiber wand is the best brush. 

Why? 

Because it goes circle f contour and coat equally.  the orbital contour. 

Method: 

adjust at the roots and draw up in linear pattern. 

Giving mixing of lengthening and volumizing

• Eyes with Hoods Structure

Over the lash line, the lid skin folds. Smudging and the loss of lashes are the issue. 

The best brush is a rubber or slim curved brush. 

Why? 

Because smaller brushes prevent lid contact. 

Technique.

Only focus on the outer lashes. Mascara in a tube (which reduces transfer)

• Eyes that are round Structure 

The sclera, or eye's white, is more obvious. 

Goal

Make the shape longer. The ideal brush is a straight comb. 

Why? 

Provides directional control in the direction of outer corners. 

Method 

Pull the lashes outward rather than upward. Mascara with a lengthening formula

• Eyes with No Lids Structure(Monolid)

No crease can be seen. The issue is curl collapse. 

The ideal brush is a thin, curved wand. 

Why? 

Provides lift without weighing down the lashes. 

Method 

Before curling, slightly heat the curling iron. Mascara made of a lightweight polymer base

• Dedicated Eyes Structure(Deep set) 

The eye socket is deeper. 

Problem

Lash visibility is diminished by shadowing. 

The best brush is a dense volumizing brush. 

Why? 

It creates depth and contrast. 

Method

Don't apply heavy coat instead apply two light coats

Formula

formula for buildable volume

Breakdown of the Ingredients and Formula (Label Literacy) 

Make sure check mascara ingredients list of ensuing,

• Carnauba, beeswax 

adds weight while thickness is added. 

• Copolymer of acrylates 

maintains curl 

• Panthenol 

a form of vitamin B5 nourishes the lashes 

• Ferrous oxides 

Source of pigment 

• Graphite black 

A darker shade of black (which may irritate sensitive eyes)

Avoid these if you have sensitive eyes

• Fragrance
• Preservatives releasing formaldehyde
• a lot of alcohol

Common blunders with mascara that ruin results 

• inserting the wand into the tube (adds air and dries the formula) 
• Wet mascara should be applied right after curling. 
• Heavy layering without waiting for it to dry 
• utilizing mascara that is no longer in use 
• Using the same style of brush for each eye shape

How to Keep Mascara from Smudging for Longer Use

• tissue to remove oil from the lash line. 
• Wrapping the lids with translucent powder. 
• Giving each coat to dry for 30 seconds.
• Use tubing mascara for oily lids. 
• Keep the wand clean on a weekly basis.
