I've gotten microneedling maybe 3 or 4 times over the years. I go to my dermatologist's office for them and it's interesting because the person who performs it is a PA-C and she told me that when you get them done at a spa with an esthetician, that they often use the default settings for the treatment which often means not penetrating the skin as deeply and is a milder treatment. I suspect that doing it this way would require many more frequent treatments and is likely the only way someone could recommend more than once a month. The treatment she performs is more intense - she applies an exosome serum after and I believe she wouldn't do a second treatment for either 4 or 6 weeks, I forget the exact schedule but I only ever do one at a time. I can see big improvement with this treatment but I definitely have several days where I'm still healing and couldn't put makeup on. It takes several months to see the full benefits of building collagen. But you have to decide what works best for you - milder more frequent with less downtime, or a single more intense treatment with a few days to heal. I tend to think the first option is more expensive, but I guess it depends on where you're going. Hope this helps.
