Lasers & Lights

Light can be a powerful force for skin repair and rejuvenation, as the energy from lasers and other light treatments heats up darker-pigmented cells in unwanted lesions, hair follicles, and more.

Treatments include laser hair removal, LED light therapy, IPL, fractional laser skin resurfacing, and photodynamic therapy.

Skin Rejuvenation

Skin rejuvenation options at The MedSpa by CT Derm focus on encouraging skin cell turnover, collagen production, and other natural processes that repair damage caused by the sun and time.

Treatments like chemical peels and microdermabrasion exfoliate the surface, while microneedling creates microchannels that prompt fibroblast activity and collagen induction absorption.

Here is What our Patients Think

All of the interaction with the staff, technicians and doctors have been professional and friendly. The staff is efficient, the wait times are minimal, and the care is exceptional. I highly recommend CTDerm.

Wade W. (Patient since 2019)

I have known from a distance that Dr. Thornfeldt and his staff were very good. But in just one visit, I realize that I had underestimated how good they are. Our son and daughter's skin issues, as well as my own, were not noticed by our dermatologist where we live. It was fully worth the trip from Florida.

Robert H. (patient since 2016)

My experience with Dr. Thornfeldt and his staff has been nothing but pleasurable. The staff are friendly and helpful going the extra mile to meet the patients needs. Dr. Thornfeldt is dedicated to the care of his patients, actively listening and responding as he seeks to see the bigger picture.

Dezra. R (patient since 2019)

The staff at CT Derm is very friendly and helpful. I found the visit very comfortable. Dr. Thornfeldt is extremely knowledgeable, thorough, and understanding. I am a former patient of his from when he had an office in Nampa, but due to improved skin issues and major life changes, -- a divorce and move, I didn't follow him to his Fruitland office. After over 12 years, and new skin problems, I knew it was time make the drive. I trust him completely and appreciate his experience and expertise.

Ellen S. (patient since 2018)
