Biology Crash Course: An Overview of the Life of Eyelashes

Did you know eyelashes protect our eyes and contribute to overall eye health?

Eyelashes act as a barrier between our eyes' external and internal environment, preventing dust, debris, and other particles from entering. An optimal lash length is necessary to reduce the number of particles that can reach our eyes, which is essential for shielding the cornea and other eye structures. They are also sensitive and have a unique reflex response that helps protect our eyes. When something comes in contact with our eyelashes, it triggers an immediate response that causes our eyes to close. This reflex response serves as an additional protection layer, shielding our eyes from potential harm.

In addition to their protective roles, eyelashes preserve the health and comfort of our eyes. They do so by creating a barrier against airflow that prevents excessive evaporation of tears, regulating the moisture levels around the eyes, and maintaining optimal eye health and comfort. By retaining the necessary moisture, our eyes stay lubricated and nourished, preventing dryness, irritation, and other eye-related problems.

Not only do eyelashes serve as a protective barrier for our eyes, but they also have a significant aesthetic and expressive purpose. They play a vital role in enhancing the overall appearance of our face by framing our eyes and adding a touch of elegance and beauty to our look. With a boost to your self-esteem, you'll be sure to feel confident and ready to take on the world.

Anatomy of an Eyelash

The structure of an eyelash is simple, yet it has a crucial role in protecting the eyes. Here's an overview of its basic structure:

Dermal Papilla

The dermal papilla is a small projection located at the base of the lash follicle. It's highly vascularized, meaning that it has a rich blood supply, which allows it to provide essential nutrients and oxygen to the cells responsible for lash growth, helping maintain the structure and integrity of the hair shaft.

Follicle

An eyelash comes from a hair follicle, a small pocket in the skin where the eyelash grows. The follicle has cells that rapidly divide during the anagen phase of the lash growth cycle, resulting in the formation of the eyelash.

Bulb

The bulb, the rounded and swollen base of the hair follicle, is where cells actively divide during the anagen phase and produce new lash cells.

Root

The eyelash's root is the base, embedded in the hair follicle from where it initiates growth.

Hair Shaft

The eyelash comprises a hair shaft consisting of keratin, the same protein found in hair and nails. This hair shaft gives the eyelash structure and strength, extending beyond the skin's surface.

Sebaceous Gland

Near the hair follicle, a sebaceous gland produces an oily substance called sebum. Sebum contributes to the overall health of lashes by keeping them flexible and nourished.

structure of an eyelash

The hair shaft comprises three main layers: the cuticle, cortex, and medulla.

Cuticle
The cuticle refers to the hair shaft's outermost layer, consisting of thin, overlapping, scale-like structures. Its primary purpose is to provide a protective covering for the inner layers of the hair by safeguarding it from any damage caused by environmental factors and styling practices.
Cortex
The cortex is the layer in the middle of the hair shaft. It is made up of elongated cells and contains keratin, a fibrous protein that provides strength and elasticity to the eyelash. Additionally, the cortex is responsible for giving color to the eyelashes due to the presence of melanin - the pigment responsible for hair color. The color of your eyelashes depends on the arrangement and density of melanin.
Medulla
The medulla is the central layer of the hair shaft that lies at the innermost part. It is composed of loosely packed cells. Though not all hairs contain a medulla, its presence, size, and structure may vary between individuals and even different hairs on the same person. The exact function of the medulla needs to be better understood, and it may not have a significant role in the overall properties of the hair.

the growth cycle of lashes

Here's a fascinating fact: the human lower lid possesses 3-4 rows of 75-80 lashes, whereas the upper lid has 5-6 rows of 90-160 lashes. Each lash undergoes a cyclical process of growth with three phases: anagen (growth), catagen (transition), and telogen (resting/shedding). The complete life cycle of eyelashes, including the growth of a new lash and the shedding of an old one, typically takes several months, with the total cycle duration ranging from four to six months. However, some individuals may experience a cycle lasting up to 11 months, depending on their genetics, age, and overall health.

anagen phase

The anagen phase, also known as the growth phase, is a crucial stage in the life cycle of eyelashes. It's the active period in which the lash follicle is stimulated to produce new cells, leading to the development of a new lash.

The anagen phase begins with activating lash follicles. Once stimulated, the matrix cells at the base of the hair follicle undergo rapid division. This cell division contributes to the lengthening of the hair shaft and is a key process in lash formation.

During this time, the lash follicle receives a rich blood supply, ensuring the delivery of essential nutrients to support the growth of the lash and providing the necessary building blocks for keratin formation. This protein makes up the structure of the lash.

This phase is the period of peak growth for the eyelash. Lashes can grow approximately 0.12 to 0.14 millimetres per day. The cumulative effect of this growth over the entire duration of the anagen phase determines the final length of the lash.

The duration of this phase varies from person to person but lasts, on average, between 30 and 45 days. Not all lashes are in the same phase simultaneously. Each individual lash goes through its growth cycle independently, meaning that some lashes are actively growing while others may be in the catagen or telogen phases. This ensures that not all your lashes fall out at the same time when the falling-out phase starts.

Taking good care of your lashes during this active growth period can contribute to the appearance of longer and healthier lashes. So, if you want to make the most of this amazing phase, why not use our lash serum? It's like giving your lashes a boost of goodness to help them grow to their full potential.

What impact does our lash serum have on this phase?
Our lash serum is formulated with active ingredients, including peptides and vitamins, specifically designed to stimulate hair follicles. By enhancing follicle activity, our lash serum encourages a longer duration of the anagen phase. This can contribute to the development of longer and thicker lashes. Additionally, our serum strengthens lashes and promotes a healthier lash structure, reducing premature shedding and allowing lashes to reach their full growth potential. Certain ingredients in our lash serum can also boost keratin production, contributing to the overall strength and resilience during this growth phase.

catagen phase

The catagen phase, also known as the transition phase, is the second stage in the life cycle of eyelashes. During this phase, the eyelashes undergo a natural transition from the active growth phase (anagen) to a period of regression, which is a regulated part of the lash growth cycle.

As the catagen phase begins, the hair follicles contract and shrink, gradually ceasing active growth by reducing blood supply and nutrient flow to the lash. The contraction of the follicle stops the growth of the lash, and the cellular activity that characterizes the anagen phase decreases.

This transition typically lasts around two to three weeks and prepares the lash and its follicle for the subsequent resting phase (telogen).

It is important to note that if a lash falls out or is pulled out during this phase, the eyelash will only grow back once the cycle finishes and the Anagen phase begins again.

What impact does our lash serum have on this phase?

Its unique formula can help you maintain stronger and healthier lashes by contributing to a smoother transition from the growth phase (anagen) to the resting phase (catagen). It minimizes premature lash loss and reduces the likelihood of breakage, which can lead to longer-looking lashes even as they transition. Our serum is enriched with nourishing ingredients that can provide optimal nutrients to the lash follicles during the catagen phase when they prepare for the resting phase (telogen).

telogen phase

The telogen phase is the final stage in the life cycle of eyelashes. This phase, also known as the resting or shedding phase, is when the lash is dormant, and there is no active growth. By the start of the telogen phase, the lash is entirely disconnected from the follicle's blood vessels and undergoes changes to form a club hair. This non-growing hair structure remains attached to the follicle but no longer actively lengthens. This prepares the old lash for eventual shedding, which is a normal and necessary part of the lash growth cycle.

Once the telogen phase ends, the old lash is naturally shed, and a new lash starts forming in the anagen phase within the same follicle, which is essential for the continuous renewal of eyelashes. It is worth noting that the telogen phase lasts an average of 100 days, making it the longest of the three lash growth phases. Around 50% of your lashes are in this phase at any given time.

What impact does our lash serum have on this phase?

Our lash serum effectively prevents lash thinning, which is particularly beneficial during the telogen phase. Ensuring the thickness of lashes during the resting period can enhance their volume when new lashes grow during the subsequent anagen phase. Our lash serum not only impacts the anagen phase but also helps maintain lashes' overall health and strength, leading to a smoother transition from the telogen to the anagen phase. With our serum, you can be confident that your lashes will progress efficiently through the growth cycle, resulting in healthy and voluminous lashes.

why is it important to understand the growth cycle of lashes?

Understanding the cyclical nature of lash growth helps you set realistic expectations regarding the timing of results when using our lash serum. It's important to recognize that lashes undergo natural shedding, and visible changes may not occur immediately. Overusing products, especially during certain phases, may not provide additional benefits, so avoiding excessive application is best. Being familiar with the factors influencing lash health throughout the growth cycle enables you to adopt practices promoting overall lash well-being. By avoiding harsh makeup removal techniques and protecting your lashes from environmental stressors, you can confidently enhance the health and beauty of your lashes.
