About Joske: Created by Marta Tālberga

I’ve been a lash and brow artist for over 10 years, specialising in lash extensions, lash lifts, and everything brows.

From the very beginning, I’ve always believed that healthy natural lashes are the foundation for any beautiful result, which is why I’ve always recommended and sold lash serums to my clients.

For years, I trusted the other lash serums available in New Zealand, until I started hearing from my clients that lot of them were experiencing irritation, sensitivity and other side effects after using them.

That led me to look deeper into what was actually inside these serums, and I discovered that most of the lash serums sold in New Zealand contain prostaglandin analogues, ingredients that can cause irritation, redness, darkened eyelids, and even changes to your eye shape or lash line.

I then started searching for a prostaglandin free serum that I could truly trust and recommend, but none of them were made in New Zealand. Every single one was produced overseas, and I wanted something local, safe, and made with care.

That’s when I decided to create my own.

After nearly three years of development, with the help of an amazing New Zealand team, Joske Lash Serum was born, a prostaglandin free, Made in New Zealand, and sensitive eye friendly lash serum that you can use confidently, even with lash extensions.

I’m so excited to share it with everyone who believes in healthy, natural beauty.


Joske Cosmetics is built on years of experience, passion, and a genuine love for lashes that look and feel their best.

I truly hope you love it as much as I do.

Our Philosophy

After almost three years of research, testing, and passion, Joske Cosmetics was born in New Zealand.

Created by a lash artist who has seen it all, this serum was made for real results without compromising lash health or eye sensitivity.


We wanted something powerful yet gentle, free from prostaglandins and harsh chemicals that can cause irritation or unwanted side effects. Prostaglandin analogues, often used in other lash serums, can cause redness, darkening of the eyelids, eye sensitivity, and even changes to eye colour over time, which is why we chose to stay completely prostaglandin free.


Every bottle represents care, quality, and New Zealand craftsmanship, made locally with premium active ingredients that truly work.


Our mission is simple: to help you grow naturally beautiful lashes, confidently and safely.
