Who is Oller?

I’m Oller.

I studied Cosmetic Science in Korea —
I actually changed my major just to study it.

Before starting a real job, I came to Australia
on a working holiday. One challenge before settling down.

But somewhere along the way, I wanted to stay.
So now I’m working as a tiler in Brisbane,
preparing for a student visa,
and aiming for permanent residency.

And at the same time, I’m building olerror —
a cosmetic brand, from scratch.
No factory. No funding.
Just the process — raw and real.

This blog is where I write about that process.
Skincare science, the brand I’m building,
and the raw, unfiltered life of doing it all
while working construction in a country
that isn’t my own.

I’m also documenting everything on YouTube.

I don’t know if I’ll make it.
But I’m writing it all down anyway.

Let’s go together.
