About OSAZ™
Tinted sunscreen that actually matches your skin AND protects it.
OSAZ™ is a science-backed beauty brand creating 2-in-1 tinted SPF and lip protection for every complexion. We formulate mineral-based sunscreens that work like your favorite foundation; no grey cast, no flashback, no “summer shade / winter shade” drama, just believable coverage and real UV protection.
Born in Lagos and built between Nigeria and the United States, OSAZ is powered by AI and real skin data, helping us understand how different tones, undertones, and climates interact with SPF. Every product we make is informed by the faces we see every day; from Lagos heat to LA sun.
OSAZ was founded by Osazomon Imarenezor, a computational skin biologist and cosmetic scientist who studied skin diseases and pigmentation differences across West Africa and the U.S. Frustrated by the lack of inclusive, effective sunscreens, she set out to build products that are beautiful enough for your makeup bag and serious enough for your dermatologist.
Our formulas are:
-
Tinted & inclusive – shades designed to blend into real skin, not just “light/medium/dark.”
-
Science-driven – rooted in research, stability testing, and ingredient transparency.
-
Made for daily life – lightweight, non-chalky textures that can survive Lagos humidity and everyday city hustle.
From sun-glazed lips to full-face coverage, our goal is simple:
Make SPF the sexiest, easiest step in your routine—so you actually wear it every day.
Stay close for new drops, shade expansions, and SPF education.
