Which is better, carboxytherapy or microneedling for stretch marks?

Stretch marks need a combination approach for improvement. I recommend a combination of microneedling/prp, lasers (Erbium/Fraxel Laser, Excel V, Pulsed Dye Laser) or radiofrequency devices. Stretch marks can't be cured and it will take a series of treatments. I recommend you see an expert for a formal evaluation. Best, Dr. Emer

Unfortunately, stretch marks are a common occurrence and can be difficult to combat. The best way to approach them is with a combination of treatments. In our office, we use RF Microneedling by INTRAcel which works by creating microchannels in the skin that encourages your body to begin it’s natural collagen production process, resulting in visibly firmer, healthier looking skin, and the addition of radiofrequency energy further heats the collagen-producing layers of the skin, resulting in significant improvements. We’ve seen good results with this technique in our office with multiple treatments, however, an in-person consultation with an experienced skin provider will help you determine the best course of action!

Microneedling with PRP is helpful in my experience with stretch marks. I would also consider using tretinoin (Retin-A) on the stretch marks as well.
