Can RF Microneedling cause raised scarring or permanent needle scars since the needles go so deep and heat up?

you need to consult, as I have never seen scars with proper treatment. pre and post skincare is essential and most MNRF doesnt work for stretch marks either.

at home peels like cosmelan, enlighten and aerify along with dermarolling (EmerageSkin roller with anteage AERIFY MD ampules weekly, see link) should be started now to prevent further aging.

For facial rejuvenation, I would suggest a combination approach of
1) skin care with products and PRP/microneedling
2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant regularly and a few times a year Fraxel/halo Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production with fillers like juvederm/restylane/belotero/radiesse/bellafill
5) thermage/ultherapy for yearly skin tightening with or without PDO or cone based instalift threads for lifting
6) botox every 2-3 months to stop movement lines and prevent lines at rest
7) deep microneedling RF like Fractora/morpheus8 for tightening of the skin
8) Vascular laser like vbeam/excel V or BBL forever young treatment every quarter (3-4 months)

Best, Dr. Emer.

Stretch marks are very difficult to get good results. Microneedle with RF in combination of PRP injections offer a good option. The needle can go up to 3mm deep and on high setting will create scabbing but not likely to cause scarring. expect 30-50% improvement with 3-5 treatments.
