Hi! Excellent question you have here! Yes, you candefinitely undergo microneedling treatment sessions after you have had yourhyaluronic filler procedure. Fillers are often injected in the deep part ofyour skin. Microneedling does not go that deep as it only works in the skin’s top most layer – the dermis. Waiting for at two to three weeks shouldalso do you well especially if your filler treatments do not go as deep as theothers do. At this point, microneedling will not be able to affect the injectedfillers. On the other hand, if you have not undergone fillertreatment yet, you may want to go for microneedling first. Microneedling priorto filler treatment can help in enhancing the effects of the fillers, asmicroneedling will stimulate collagen production to give your skin a moreyouthful glow. Consult your board certified plastic surgeon so he orshe could advise you the best way to go. But as mentioned, if you have alreadyundergone filler treatments, there is no harm in doing microneedling after solong as you wait for a few weeks. Hope you find this helpful!
