Currently, all the skincare staples, like hyaluronic moisturizer and natural konjac sponges, are developed through co-manufacturing partnerships.
“ I intentionally source from partners who align with Lumithéa’ s clean beauty standards and values, especially those who specialize in plant-based, gentle formulations” Miles said.
She added that she considered many factors when deciding whether to co-manufacture or to craft her Lumithéa products in-house.
“ It’ s a mix of quality, expertise and scale. If a partner can produce something at a higher standard or more sustainably than I could in-house, that’ s a strong indicator to co-manufacture.
“ I also consider the time and cost of sourcing individual ingredients, formulation testing and compliance. Being a small business, the cost and time required to do research and development alone for a start-up beauty business would bankrupt me before I could even consider design or packaging.
Miles said co-manufacturing allows her to deliver excellence without sacrificing speed, quality or safety. The approach allows her to deliver something she can be proud of and that consumers can feel confident about. But the process has involved trial and error.“ I’ ve worked with more than one manufacturer as I refined Lumithéa’ s product lineup. Some partnerships were short-lived because they couldn ' t meet the quality or customer experience I wanted,” she said
“ But over time, I’ ve built a strong relationship with a trusted partner who understands my standards and shares my vision. Having said that, I’ m also actively exploring partnerships with sunscreen manufacturers, since SPF is FDA-regulated and requires more rigorous approvals.”
Like many small business owners, Miles started out by trying to do everything herself, quickly realizing that to grow, and to maintain consistency and compliance, she’ d need support.
“ I started researching co-manufacturing through online forums, beauty industry groups and word of mouth. Eventually, I connected with labs and suppliers who work with indie brands and understand the nuance of bringing a founder’ s vision to life.” The process had a definite learning curve, said Miles.“ I started with clear non-negotiables: clean ingredients, small-batch flexibility, transparency and alignment with my brand values. Then it became about communication and trust.”
Miles asked for samples, vetted their sourcing, and paid close attention to how they responded to questions. She said that if a manufacturer couldn’ t
explain their processes or didn’ t respect her creative input, it was a no.
Asking lots of questions is essential, she said: what’ s in a product, how it’ s made, how it will feel to the customer. She notes that the best co-manufacturing relationships feel like creative partnerships with each bringing something vital to the table. Still, there can be some missteps among the successes.“ The good surprises have been moments where a partner exceeded my expectations, like changing the ingredient list when I realized a key ingredient was missing from the label, and they made it right quickly,” Miles said
“ The tough surprises usually came early on, when timelines slipped or batches weren’ t consistent. Those moments taught me to document everything, ask better questions, and trust my gut when something feels off.” But, she said, the vetting to find complimentary comanufacturing partners was all part of the process of success.“ Co-manufacturing has shifted Lumithéa from being a passion project to a scalable brand,” she said.
“ It’ s allowed me to build a more professional infrastructure— streamlining production, creating consistent quality and giving me space to think longterm. It’ s also helped me see my role not just as a maker, but as a visionary and curator of the entire brand experience.”
“ Because I’ m not bogged down in production logistics, I can dream bigger. I’ ve been able to explore more niche formulations, seasonal kits and even digital-physical hybrid experiences.
“ Co-manufacturing gives me a solid foundation to experiment from— knowing that the backend can keep up with the front-end innovation.”
For Northeast Florida businesses looking at a co-manufacturing partnership of their own, Miles offers advice.
“ Start with clarity— know what you stand for, what you’ re offering, and what non-negotiables you have when it comes to ingredients, ethics and customer experience.
“ Co-manufacturing can be a game-changer, but only if you partner with people who understand your vision. Take your time choosing the right fit. It’ s a relationship, not just a transaction.”
