Can I do RF microneedling on my face when pregnant?

Most specialists will say no based upon absolute safety during pregnancy. Best to wait post partum. 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,

While this is one of my favorite cosmetic treatments, I would wait until after delivery before scheduling your microneedling treatment. Many things cannot be offered to pregnant women because there is no hard evidence that it is "safe. " It is always best to err on the side of caution while you are growing your little one. Commonly topical lidocaine cream is used to numb the face prior to the procedure and this is not recommended during pregnancy.
