Does microneedling RF improve or soften internal, deep scar tissue from hematoma?

Hello Justicia,I have never seen our INTRACEL RF Microneedling Device make scarring worse. For acne scars it helps reduce the scarring. I don’t know how significant your scar is as I don’t see a photo, but I would not be concerned at all about increasing scar.

Haematomas are best treated with either vvv low steroid injections, or saline. RF can break this up, additionally fibre optic delivered lasers can help. Microneedling RF is an extension of microneedling with ‘energy’. Generation one devices such as Dermapen/ Skin Pen etc. use needles without heat to remodel collagen. Generation Two devices are microneedles that are not insulated, hence heat is delivered along the length of needles. Examples include Secret RF and Intensif. Generation Three devices use insulated needles to deliver heat at the point of the needle. Examples include Infini RF, as well as Genius. 
Newer generation devices will generally give better outcomes, however with insulation, the safety of microneedling RF devices is usually better than generation two machines. With insulation the incidence of skin colour darkening and ‘grids’ secondary to ‘stamping’ is less, however it is largely technique dependent. 
Microneedling RF should be viewed as a tool to be incorporated in the suitable clinical context. As with most other ‘fractional technology’ 3-5 sessions spaced 3-6 weeks apart will give the best results. Be guided by your specialist.  All the best,
