Clinicians Bust Lash Growth Myths

Most lash advice is wrong.
And it could be costing you time, money, and even lash health.

I have spent over 10 years in healthcare as a prescribing pharmacist. I know how to read research, question it, and decide what actually works. Most brands? They just believe whatever the lab tells them.

Here’s what you need to know if you want longer, healthier lashes without the risk.

Myth 1: Lash Serums Work Overnight

Truth: Your lashes grow in cycles. Even the best formulas need 4–8 weeks to show real change. Overnight promises are designed to sell products fast, not deliver results.

Myth 2: More Product Means Faster Growth

Truth: Your lash follicles can only absorb so much. Overuse wastes product and increases irritation risk. One thin swipe per lash line, once daily, is enough.

Myth 3: All Lash Serums Are the Same

Truth: They are not. Many use prostaglandin analogs — synthetic hormone-like ingredients with known side effects.
Nuur Lash difference:

100% prostaglandin-free
Preservative-free
Clinician-developed for sensitive eyes

Myth 4: Extensions Are Safer

Truth: Adhesives and weight damage your natural lashes over time. If you wear extensions, take breaks and rebuild lash health in between with a safe serum.

Myth 5: Oils Work Just as Well

Truth: Conditioning is not the same as stimulating growth. Castor oil can help condition, but it will not increase lash length or density like peptides and biotin can.

How to Choose a Serum That Works and Is Safe

Avoid prostaglandin analogs
Check for transparent formulation claims
Look for clinician-developed products tested for sensitive eyes
Be patient — real growth takes consistency

Others believe what they are told. We analyse, question, and only approve what the science supports.

Why Clinician-Developed Matters

Eye health is delicate. I built Nuur Lash to be safe enough for daily use and effective enough to deliver visible results — without risky ingredients.

Final Word

Stop wasting time and risking lash health with products built on myths. Choose a serum backed by clinical insight, proven ingredients, and a safety-first approach.

The lash serum I’ll always use

Finally found something to stick with😍

Best mascara I own

In love with the mascara, however I have forgotten to use the serum so I can’t speak for that yet.

Very pleased

It’s a very nice mascara, curls my lashes well and I notice less lashes falling in the sink when I take my make up off. I’m noticing great results with the serum too, my lashes are fuller even after 1 month of use.

Favourite mascara and serum

It’s my second order for the same stuff. I use the mascara everyday, it’s different from when you first open it and when it starts to dry down. I prefer it later because it’s too messy at the beginning. I love the way it makes my eyelashes look and the closest I can compare it to is the westman atelier mascara. That was my favourite until I tried this. As per the serum, it has grown my eyelashes nicely hence why I keep on buying it.

If I could give 10 stars I would

I’m impressed with Nuur Lash. It’s grown my lashes and I finally have messy long lashes, which is something I never thought I could have. The photos are taken 3 months apart as I started it in May.
