XERF vs Morpheus8: with needles or without
Both use radiofrequency heat. Morpheus8 delivers it through tiny pins that go into the skin. XERF stays on the surface, with no needles. In October 2025 the FDA warned of burns, scarring and fat loss reported with RF microneedling. Karisma offers only XERF, at $1,500 a session, and no microneedling of any kind.

How is surface heat different from needle heat?
Morpheus8 is RF microneedling. Each pin carries current into the skin and creates a small zone of intense heat at its tip, so the energy lands below the surface in a grid of tiny points. InMode says its Burst and Scale functions fire at several depths in a single pulse, reaching both the dermis and the fat layer. That is why Morpheus8 is used for texture and scarring as well as laxity.
XERF never breaks the skin. Its FDA file lists the contact as intact skin. Heat spreads from the tip through the tissue toward a return pad on your back, while a cryogen spray cools the surface. Less is happening at the surface, and nothing is left open to heal.
What the FDA said about RF microneedling in October 2025
The notice covers RF microneedling devices used for skin appearance. It does not name a brand.
- Reported complications include burns, scarring, fat loss, disfigurement and nerve damage, some needing surgical repair.
- RF microneedling is a medical procedure, not a cosmetic treatment, and these devices should not be used at home.
- Patients should seek care from a licensed health care provider trained on these devices and ask which device will be used.
- Problems should be reported to the FDA.
InMode's own Morpheus8 page lists the same reported complications.
Are there skin tone limits for each?
Morpheus8's 2023 clearance carries a condition: at energy levels above 62 mJ per pin, use is limited to skin types I to IV. Ask any Morpheus8 provider what your skin type is, whether that limit applies to you, and what settings they plan to use.
XERF's cleared label has no skin type line. Cynosure says it suits all skin types, and a provider on Cynosure's blog reports treating light to very dark skin. Those are claims from the maker side. The largest published XERF study, 39 people in Cureus in March 2026, enrolled only skin types I to IV, the same range as Morpheus8's high-energy limit, and its authors say results for types V and VI are uncertain.
Why doesn't Karisma offer Morpheus8?
Florida's cosmetology rule 61G5-18.00015 defines microneedling as making channels in the skin 0.25 to 2.5 mm deep and places that piercing beyond the scope of a facial specialist. Kay is an esthetician, so microneedling of any kind, with or without radiofrequency, is off the menu. If you want Morpheus8, book with a physician-led practice.
Morpheus8 may suit you if
Your main concern is texture, enlarged pores or acne scars as well as laxity, you accept needles and healing time, and you are treated under a physician's care.
XERF may suit you if
You want heat without needles or open skin, your concern is mild looseness, and you accept that XERF's published evidence is two small studies, 39 people and 16 women. At Karisma it is offered on the face and neck.
Questions about XERF vs Morpheus8
Is XERF safer than Morpheus8?
No study compares them. The FDA's 2025 notice on burns, scarring and fat loss covers RF microneedling, the group Morpheus8 belongs to. XERF has no such notice, but its published safety data come from small numbers of people, so rare problems would not show yet.
Does Morpheus8 cause fat loss?
Fat loss is on the FDA's list of serious complications reported with RF microneedling devices, and InMode's site lists it too. It is a reported risk, not an expected result. Ask any provider how they set depth and energy over thin areas of the face.
Can an esthetician do Morpheus8 in Florida?
No. Florida rule 61G5-18.00015 places microneedling beyond the scope of a facial specialist. More on the limits in what an esthetician can do in Florida.
Which is better for acne scars?
Morpheus8 has published work on acne and scarring. XERF has no published acne scar data. Read the acne scar options first, and see a dermatologist for scarring.
