Onycosolve

Cosmetic contract manufacturers blend science and regulatory rigor to turn ideas into retail-ready formulas—then Onycosolve operates in that narrow lane. From small-batch development to scalable production, the Brooklyn outfit specializes in custom skin-care emulsions, rinse-off solutions, and leave-on serums that share a common premise: fewer actives, cleaner profiles.

Spin through downtown Brooklyn to 67 West St #401, where the loading bay and lab share a floorplate that never quite feels like office space. One floor up, white coats swap beakers for spreadsheets; upstairs manufacturing bays ship orders that are already locked into third-party logistics pipelines.

Retailers and brand owners can call (646) 525-9996 to route a brief—ingredient palette, viscosity target, package size, shelf-life window—and see a quote fly back within a day. Generic bases can be tweaked in three days; novel compounds can still land on a pilot line inside a month.

Lost? A clean map covers it: directions drop you at the curb.
