This has been a 10-year journey of learning, failing, starting again, and building something I really believe in.
And honestly? We’re only just getting started. 🖤🥹✨🫶🏼

The year I started my makeup career. When I took a risk leaving school for something people didn’t believe-in. The year I didn’t give up.
We all start somewhere. I didn’t know it then, but this was the first step to everything I have now 🤍
Before we launch our next lash collection, I want your opinion - because there’s no point launching products you don’t actually want to wear 🫶🏼
Tell me:
✨ Winged or doll?
✨ Soft or dramatic?
✨ Everyday or glam?
✨ Half or Full Lash?
Comment your favourite style - this genuinely helps shape what we launch next for By Caitlyn 🤍
Save this so you can come back to it when you’re doing your makeup 🤍
Our customers said it better than we ever could 🥹
