I first came to Dr. Rainey to seek help with a cyst I’ve had for a few years now and he has absolutely gone above and beyond in his services. He took care of the cyst and put me on a skin routine that has made a huge improvement on my face and skin. I’m incredibly grateful to have ended up in Dr Rainey’s care.
Response from the owner:Helping with a cyst that’s been bothering you for years and then seeing your skin routine make a real difference is exactly the kind of progress we hope for. We’re so glad Dr. Rainey could be part of that turnaround and that your skin is feeling better too.

My first time ever being seen by a Dermatologist and had a great experience in doing so. Staff was great and so was Dr Rainey. I had 3 concerns and unexpectedly attended to them within the same visit. Dr Christy Rainey is awesome and has great bedside manners. I will be scheduling my mother for some services that she’d love to get here soon.
Response from the owner:Three concerns handled in one visit is exactly the kind of care we hope for. We’re glad Dr. Christy Rainey and the staff made your first dermatology appointment feel easy and thorough, and it’s wonderful to hear you’d trust us with your mother too.

Botox treatments are minimally invasive and typically well-tolerated. The procedure involves small injections, and we use techniques to ensure your comfort throughout the process.

After a laser hair removal session, you may experience mild redness or sensitivity, which typically resolves quickly. For optimal results, multiple sessions are recommended.
