First, ask where the CO2 comes from and how the device controls the delivery.
CO2 used for injections should have a medical purpose and an identifiable source. The salon should know the gas documentation, storage method, and filtration system compatible with the device. The answer "it is just regular carbon dioxide" is insufficient, as gas contact with tissue is not the same as food or technical use.
The device must control the flow and volume, and the operator adjusts them to the zone. In J'ADORE materials, carboxytherapy is associated with the Julia/Reology device, described as a system for precise medical CO2 dosing. You do not need to know the settings. You should hear why the eye area and the body require a different plan.
Qualification must determine whether the goal actually matches the mechanism.
A dark circle under the eye may result from visible vessels, pigment, volume loss, swelling, or several causes. Carboxytherapy is not an identical answer to each of them. Similarly, "cellulite" may contain an oedematous component, fibrous tissue, and laxity. The specialist should name the dominant problem and indicate what will be measured.
The interview covers cardiovascular diseases, coagulation disorders, medications, pregnancy, active infections, skin inflammation, and healing history. The full list depends on the procedure and current instructions. Concealing a medication to avoid missing an appointment deprives the person performing the qualification of the data necessary for a decision.
- Who is qualifying me and what are their credentials?
- What type of problem do you recognise in this zone?
- What definitively excludes the treatment, and what only postpones it?
- When do you recommend a medical consultation instead of carboxytherapy?
Injection hygiene must be visible, not assumed.
The needle and disposable elements should be opened in your presence, and the skin properly prepared. The operator works in gloves, does not touch a phone, door handle, or hair after disinfection, and then does not return to the injection site with the same hand. The sharps container should be within reach of the workstation.
Ask which elements of the gas line are disposable and how often filters are replaced according to the manual. A declaration of salon cleanliness does not replace a procedure. Many injections mean many opportunities to break the rules of asepsis.
The feeling of pressure is not a test of character.
After the injection, you may feel heat, tension, or pressure related to the gas delivery. The intensity depends on the zone, flow, and individual sensitivity. The operator should warn you about the sensations and observe the tissue, rather than hold a conversation from the other end of the room.
Increasing, sharp pain, severe blanching, systemic symptoms, or a reaction inconsistent with the description require stopping and assessment. The phrase "carboxy must hurt" is not a protocol. Endurance does not measure the quality of the result.
Ask how the operator modifies the flow and what they do when the tissue reacts differently than expected. A good answer includes stopping the delivery, assessment, and documentation, not just calming you down.
A series should have a control point and a termination criterion.
The number of sessions depends on the goal and the zone. Before you buy a package, find out when the first assessment will take place and how the specialist will know that the method is working. For dark circles, photos without makeup in constant light are important; for the body, position, hydration, and swelling also matter. Without constant conditions, any result can be attributed to the treatment.
The plan must also answer what will happen if there is no improvement. Adding more sessions without re-diagnosing the problem may only increase the number of injections. Sometimes it is more accurate to change the method, seek medical diagnostics, or accept that a given feature cannot be significantly changed by this procedure.

Aftercare instructions should distinguish between a typical reaction and an alarm one.
Temporary redness, slight swelling, tenderness, or a bruise after an injection can happen. The salon should tell you how long they usually last in a given zone and what to avoid. The information "you return to everything immediately" is too general for a procedure involving skin penetration.
Increasing pain, hot and spreading redness, purulent discharge, significant swelling, vision disturbances, or systemic symptoms require contact, and some of them require urgent medical help. Do not wait for the next session in the package. Take a photo and note the time of occurrence.
An after-hours contact channel, the name of the performed procedure, and a record of the zone should be available. If the salon refuses to provide this data, the continuity of care becomes accidental.

The injection technique must match the anatomy of the zone and cannot be a display of speed.
The eye area, scar, stretch mark, and thigh surface differ in tissue thickness, innervation, vascularisation, and goal. Ask what experience the person performing the treatment has in this specific zone. General training on device operation does not yet show whether the operator can assess thin eyelid skin and the reaction of a larger body surface.
The number of injections is not a measure of quality. More points may result from the extent, but it may also mean haste and a lack of a plan. The specialist should be able to describe the placement, direction of work, and boundaries of the area. Marking the zone before starting reduces the risk of accidental asymmetry.
Under the eye, it is also important to recognise whether vessels, pigment, anatomical shadow, or swelling dominate. Gas will not fill a tear trough and will not remove pigment like an eraser. If the salon does not distinguish these causes, even a precise injection may be directed at a target that the method does not address.
On the body, ask for an assessment in a standing and lying position. Cellulite, laxity, and swelling change the image with tension and gravity. A project designed only after lying on a treatment bed may not include the place that bothers you most in daily movement.
Do not agree to filming injections without separate consent. Media material is not part of the procedure, and pressure for an impressive shot can distract attention. The phone should not be in the clean zone or handled with the same gloves.
The salon should have an answer for a bruise, infection, and late complaint.
A bruise after an injection can happen despite correct technique. Before it happens, you need information about this risk, not an assurance that "nothing will happen for sure". Ask how the reaction is documented and when recommended preparations can be used. Home heating or massaging without instructions can worsen the symptoms.
When an infection is suspected, the speed of contact matters. Increasing redness, heat, pain, purulent discharge, or fever is not tissue cleansing. The salon should indicate the person responsible, collect information about the procedure, and refer you to a doctor when the situation goes beyond cosmetological care.
A late complaint also requires a treatment card. If you report a lump, persistent pain, or an unusual change in sensation a few days after the visit, the operator should reconstruct the zone, parameters, and course. The lack of data does not become a smaller problem just because the symptom appeared after the weekend.
Ask about liability insurance, adverse event procedures, and cooperation with a doctor. You do not expect a promise that complications do not happen. You expect proof that the place knows what to do when they do happen.
The safest salon does not downplay mild signals either. A short follow-up conversation can determine that the reaction is within the typical course. The condition is the possibility of contact and readiness to view photos or invite you for an assessment.
In Krakow, choose a place that knows how to refuse an injection.
J’ADORE INSTYTUT in Krakow is located at Karmelicka 45/2B. You can check the scope of the procedure on the carboxytherapy in Krakow page. For your consultation, please bring a list of your medications, your history of treatments in this area, and photos of the changes if their appearance depends on the time of day.
Ask for the name of the device, confirmation that medical-grade CO2 is used, a description of the single-use components, and the response plan for any unusual symptoms. The answers should be specific and tailored to the area being treated. The protocol for the eye area must not be a shortened version of the protocol for the thighs.
The strongest evidence of competence is often a refusal: in cases of active infection, an unclear shadow under the eye, a contraindication, or a goal outside the method's scope. A clinic that has only one answer — a series of carboxytherapy sessions — is not performing a proper qualification. It is simply fitting every person to the device.
