Can you do microneedling over a sebaceous cyst?

yes you can micro needle over a cyst without issues if the cyst is not active.
 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, 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
Best, Dr. Emer.

You can microneedle over a sebaceous cyst as long as the cyst is not too superficial in the skin such that the needle can penetrate the cyst. You also cannot have any acute inflammation or infection of the cyst at the time of microneedling to reduce your risk of spreading an infection. Hope this helps!

If the cyst is not inflamed or draining, microneedling can be done. However, it might be best to have the cyst first removed, and then use microneedling to help minimize the scar.
