Meet our Founder
Hi, I'm Jessica Marritt, an award-winning clinical aesthetic practitioner, multi-clinic owner, and founder of One in a ML Beauty™, featured in Forbes Switzerland and The Business Insider.
I created One in a ML Beauty™ after clients repeatedly asked if I could recommend a lip oil to use following lip injections. No matter where I looked or whom I spoke to, there didn’t seem to be anything on the market that offered a blend of nourishing formulations without compromising on aesthetic appeal and ease of application.
So, I founded One in a ML Beauty™ – a brand dedicated to providing aesthetics-led, science-backed products, safe for use both before and after lip injections.
After years of research, testing, formulation, and refinement, we are proud to launch our first product: One in a ML™ Lip Oil, and we look forward to hearing all of your amazing feedback and results.
2021
A vision to launch something the industry was crying out for.
With over 10 years of experience as an aesthetics practitioner, I recognised a clear gap in the market for a premium product that both heals and protects the lips—before and after filler treatments.
I also wanted something versatile enough to be used all year round, not just during healing. This product was created to meet that exact need.

2022
Meticulous market research confirmed our suspicion and fuelled our mission
Speaking with industry-leading aestheticians from around the world, our research confirmed the need for a product that is safe for use both before and after lip treatments—providing deep hydration, enhanced comfort, and long-lasting results.

Crafting the ultimate formula
Almost 3 years of testing, tweaking, and re-testing was conducted to arrive at the bespoke formula that is now One in a ML™ Lip Oil. Each ingredient was strategically selected to perform a specific function within the lip oil, and was hand-picked by our Founder, Jessica Marritt.
