Real results from caratin customers

Tanvee M.

Age 41.

"I’ve had toe nail fungus for years. Definitely got it from the nail salon. I started using the toenail fungus medication on my big toe and am blown away by my progress. The Caratin doctor said to give toes about 12+ months, but I’m only on month 4 and am seeing serious results already. I refuse to take oral medications because I am wary of side effects so the topical is perfect for me to be able to still treat the fungus. And for the price and convenience you really can’t beat what Caratin has to offer!

“For years I had gross toenails. I skipped beach trips, pool parties, and really anything requiring bare feet.  I’ve tried lots of over-the-counter products to no success.  I’ve been using Caratin every night consistently for months. Thank you Caratin for making this remedy for toenail fungus.”

“I took up running during the pandemic and love it - except for what it did to my big toe. Apparently, it’s common for runners to get toenail fungus because we are tough on our feet. I heard about caratin from my neighbor who had a funky toenail. I finished month 9 of the treatment and it has cured my toenail fungus.”

“I'm embarrassed to admit, but I got athlete's foot which then turned into toenail fungus. I blame it on the hours spent in the pool and locker room showers. I tried it all - stuff from the drug store and the expensive prescriptions. Nothing worked like Caratin's formula and I'm happy to report my toes are looking much healthier.”
