Fourth Youth was born from a simple frustration: skincare had become too complicated and too uncertain.

Founder Niki Hoang came from a career in tech and project management, where efficiency, precision, and results mattered. But in her own life, she found herself overwhelmed by endless 10-step routines that overpromised and underdelivered.


A devoted biohacker, Niki had long been optimizing her health from the inside out, guided by one belief: aging is something you can slow, and do gracefully. But when she looked at her skincare shelf, the science she lived by was missing.


The longevity world was transforming how we age at the cellular level, while skincare stayed at the surface. So she asked a simple question: if youth begins in our cells, why doesn't skincare? Fourth Youth is her answer, and an invitation to everyone who believes their best skin is still ahead of them.

OUR STORY
Simplifying Skincare for Modern Women with Science-Backed Solutions
As a lifelong beauty lover and biohacker, Niki saw a massive gap. Modern women don’t need more products, they need smarter ones. Products that are science-backed, multifunctional, and designed to fit into high-performing lives — not slow them down.
