Finally, something that actually works
I've dealt with yellow, thick nails for the better part of a decade. I was skeptical about Onyguard because I've bought every over-the-counter dropper and cream out there with zero luck. The pen design is what makes this different—it's completely mess-free and lets you target the nail bed directly. After about three months of daily use, the healthy nail is finally growing out clear. You have to be patient, but it works.
