Opus Plasma is not radiofrequency microneedling, even though clinics often list it next to Morpheus8. It has no needles, and nothing goes into the skin. Radiofrequency energy at the tip creates micro-plasma, which arcs to the skin surface and makes tiny controlled ablation perforations with a zone of heat beneath them. Mechanically it sits closer to a fractional laser than to any needle device.
Microneedling is the opposite trade. Fine needles physically enter the skin and make thousands of channels, with no energy and no heat at all. The wound and the healing response are the whole treatment.
Read the two clearances precisely, because they say quite different things. Opus was cleared as K201520 on 27 October 2021 to Alma Lasers. The Plasma tips, Focus and Glide, used with the unipolar applicator - unipolar meaning the current travels out from the tip through the tissue rather than between a pair of electrodes inside it - are "indicated for dermatological procedures requiring ablation and resurfacing of the skin"; the Colibri tips are indicated for "resurfacing of the skin" only. Wrinkles, acne scars, laxity, tightening and pigment appear in neither, and the clearance carries no skin-type statement. Microneedling's authorisations, by contrast, name facial acne scars outright.
The evidence is lopsided too. No Opus Plasma-specific peer-reviewed trial was found in the published literature. Microneedling for acne scars has a pooled analysis of 24 randomised trials behind it.
It shares an FDA product code with radiofrequency microneedling devices, which is one reason the two get grouped together.
No energy is involved at any point.
Nothing penetrates. The tips do not enter the skin.
Pin counts and operating frequency are not stated there either, so none are quoted here.
Wrinkles, acne scars, laxity, tightening and pigment are not named in it, and no skin type is specified.

Where clinics cite "studies", they are usually studies of other devices.
Microneedling combined with another treatment outperformed microneedling alone; microneedling with a chemical peel ranked best.
It is a fractional ablative treatment, so tiny points of surface skin are removed and marks are expected. Ask your provider for their own expected timeline in writing rather than accepting a general claim.
Conventional clinical description, not a labelled figure.
There is no published pigmentary safety data for Opus Plasma, and its clearance names no skin type at all. What can be said is structural rather than measured: Opus removes tiny points of surface skin using heat, while microneedling makes channels without heat. Heat and injury at the surface are what drive pigment problems after resurfacing treatments in general, so the two mechanisms would not be expected to behave the same way.
Nobody has measured how that plays out for Opus specifically. If you have a deeper skin tone, that is a reason to ask for a test area first, to ask what settings are planned, and to ask the provider how many people with your skin tone they have treated with this device.
Opus does not needle. Nothing is inserted, so it does not deposit heat at a chosen depth in the dermis the way radiofrequency microneedling does. It is a surface treatment.
Microneedling does not tighten loose skin meaningfully and does not reach or heat the fat underneath, so it changes texture rather than shape.
Neither is a substitute for the other, and no published study compares them.
If you get cold sores, tell your provider when you book, not on the day. Antiviral medicine is started in advance, so it has to be prescribed beforehand. Reactivation is well documented after laser resurfacing, which is where this precaution comes from.
Disclose a pacemaker or implantable defibrillator, and any metal implant near the treatment area, before any radiofrequency-based treatment. Opus generates its plasma with radiofrequency energy. These are labelled contraindications for radiofrequency devices, precautionary rather than tested, and your cardiology team is the right source of advice.
Any active infection in the area is a reason to postpone. Ask for a test area if you have a deeper skin tone, and, for microneedling, ask whether the cartridge is sterile and single-use.
