When firmness declines and fine lines or textural change appear, skincare alone can feel inadequate. Mirajet is one option: it delivers medication into the skin as a fine high-pressure jet rather than with a needle. In anti-aging care it is used to carry ingredients suited to your skin and goal, supporting texture and firmness — it is a delivery device, not a laser lifting machine that regenerates collagen by itself.

What kind of treatment is Mirajet?
Mirajet is a needle-free drug delivery device that uses laser energy to generate pressure and drive liquid medication into the skin, forming fine channels as it delivers. This differs from using a conventional injection needle.
For anti-aging purposes, medication is chosen to match skin condition and goal, supporting texture and firmness. It is better understood as a device focused on delivering what the skin needs than as a laser lifting device that regenerates collagen directly.
How does it deliver medication?
Mirajet uses a 2940nm erbium (Er:YAG) laser to create an instantaneous pressure wave that propels medication as a fine jet, delivered through microchannels in the skin.
The nozzle is a single-use medical device for drug delivery, and nozzle specification adjusts the delivered volume. Choosing the medication and delivery plan to match skin condition and area is what matters.
What change can be expected?
Anti-aging care aims at dry, dull-looking skin, fine lines, loss of firmness and rough texture. Mirajet delivers the medication used for those goals — for example, an ingredient aimed at hydration and skin condition can make skin look more moisturised and smooth. Where collagen-related or regenerative ingredients are used, the plan is built around that ingredient's characteristics.
Change in texture or firmness is not decided by the device alone: the ingredient delivered and its properties also matter. When considering treatment, confirm not only the device name but which medication is used and for what purpose.
In a study of 20 patients given three sessions of HA skin booster at two-week intervals, wrinkle scores fell 40% at week eight, with hydration, elasticity and pore measures also improving — an example of what the ingredient used alongside delivery can do.[1]
What are its advantages?
Instead of piercing with a needle, Mirajet delivers medication as a microjet — worth considering for those uneasy about needles — and it is designed for fine delivery into skin. Nozzle specification allows the delivered volume to be adjusted, so the plan can be matched to different areas of the face. With the medication and treatment extent set to skin condition and goal, it can be used to manage skin condition.
Afterwards, redness, swelling or small pinpoint marks can appear. Most are temporary, but duration varies with skin sensitivity and treatment intensity, so follow the aftercare you are given.
Which skin concerns does it suit?
Mirajet can be used for delivery of medication aimed at hydration and texture, fine lines and loss of firmness — for skin that is dry enough to make makeup lift, looks rough, or needs overall condition management. Suitability is confirmed in consultation.
Its purpose differs from lifting that physically raises deep wrinkles or a sagging contour. Where sagging is the main concern, whether radiofrequency or focused ultrasound would be more appropriate should be reviewed too.
In a systematic review of 151 studies (4,806 treatments) on striae, complete resolution was uncommon, and red striae tended to respond better.[2]

How does it differ from ordinary injections?
Conventional skin injections insert a needle and inject medication. Mirajet creates pressure with a laser and propels medication as a jet, without inserting a needle.
| Aspect | Mirajet | Conventional injection |
|---|---|---|
| Delivery | Microjet driven by pressure | Injection through a needle |
| Needle insertion | No direct needle insertion | Needle inserted into skin |
| Characteristic | Drug delivery via microjet | Depth and site controlled by needle |
| Purpose | Deliver medication suited to skin | Inject according to drug and goal |
Being needle-free does not mean no pain or skin reaction. Pain and post-treatment response vary with the medication, the area and individual skin condition.
How is treatment carried out and managed?
Usually skin condition and the goal of care are reviewed, the medication and area decided, the skin prepared, and the medication delivered with the device. Duration varies with the extent treated, the medication and skin condition.
Immediately afterwards the skin may be red or show small marks. On the day, avoid rubbing hard or using irritating exfoliants, and focus on moisturising and UV protection. Saunas and intense exercise — anything that increases heat and irritation — are usually deferred until the skin has settled.
What should be checked before treatment?
Confirm the ingredient and purpose of the medication, whether it is approved for use in skin, and the hygiene management of the nozzle. Tell your physician about any area with dermatitis or infection, or skin that is wounded. Rather than judging by the word “anti-aging”, ask specifically which ingredient is being used for your concern and what change is expected.
Mirajet: common myths and facts
| You may think… | In practice |
|---|---|
| "No needle means weak effect." | Mirajet delivers medication into the dermis under high pressure. |
| "Any ingredient gives the same result." | Results depend on the ingredient used with it. |
| "One session erases scars and striae." | Scars and striae improve gradually over several sessions. |
In a Mirajet consultation I decide which ingredient goes in before the device. Delivery is the same, but whether the goal is hydration, firmness or scarring changes the ingredient and the number of sessions.
Mirajet creates pressure with a laser and delivers medication into the skin without a needle, and in anti-aging care it carries ingredients matched to skin condition and purpose. Its defining feature is the microjet, but the result depends on what is delivered: in 20 patients given three HA skin booster sessions, wrinkle scores fell 40% at week eight with hydration and elasticity improving, while a review of 151 striae studies found complete resolution uncommon. It is not a substitute for lifting where sagging or deep wrinkles dominate, and the ingredient, its approval status and nozzle hygiene should be confirmed first.

Frequently asked questions
Does Mirajet use no needle at all?
A. It does not insert a conventional needle into the skin; laser-generated pressure propels medication as a fine jet.
Does Mirajet improve firmness?
A. Mirajet is a delivery device. The degree of firmness improvement depends on the ingredient used, skin condition and the goal of treatment.
Can I return to normal life straight away?
A. Most people do, but redness, swelling or small marks can appear immediately afterwards, so skin response should be watched and irritation avoided.
How many sessions are needed?
A. No single number applies to everyone. The plan is set by the medication, the skin concern and the area treated, with the interval and number confirmed at consultation.
