How Automatic Skin Booster Injectors Work, How They Differ from Manual Injections, and Post-Treatment Care

Hello.

I’m Wi Young-jin from Beauty’s Doctor.

When the skin feels dry or rough in texture, many people look into injectable treatments in the skin booster category.

Among them, Reedle Shot is known as a method that uses an automatic injection device to deliver ingredients at a consistent depth beneath the skin’s surface.

However, even when the same device is used, the treatment method and recovery process may vary depending on which ingredients are injected, where they are injected, and how much is used.

Rather than deciding based only on the device’s name, it is important to first check whether it is suitable for your current skin condition and care goals.

Summary in 3 Lines

  1. Reedle Shot uses a device with multiple fine needles to inject ingredients into the skin at consistent intervals and depths.

  2. Depending on the ingredients used, the injection sites, and the condition of the skin, individuals may experience different sensations during the treatment and different recovery progress.

  3. Before proceeding, be sure to fully check the ingredients used, the expected injection depth, the possibility of bruising and swelling, and post-treatment care instructions.

1) How does Reedle Shot work?

Reedle Shot Treatments: Differences Between an Automatic Injector and Manual Injections, and What to Know image 2

Reedle Shot uses an automatic injector fitted with fine needles to deliver the selected ingredients to multiple points within the skin.

Unlike the method of injecting one area at a time by hand,

the device controls the injection intervals and depth, allowing relatively even treatment over a wide area.

However, the ingredients injected are not determined simply by the name Reedle Shot.

Depending on which ingredients are used, such as hyaluronic acid or PN-based ingredients, the treatment goals and post-treatment reactions may vary.

During the treatment, the repeated contact of the needles with the skin may cause a prickling or pressing sensation.

Areas with thinner or more sensitive skin, such as around the nose and on the forehead, may feel somewhat more uncomfortable.

2) What should be checked before proceeding?

During the consultation, it is advisable to first check the name and ingredients of the product being used, whether it is an authentic product, and how it will be opened.

This is because even the same ingredients may cause different skin reactions depending on the amount and depth of injection and the treatment site.

If there is inflammation or an open wound on the skin, or if the area is prone to recurring herpes, the treatment may need to be rescheduled.

Please also inform the medical professional in advance about any medications and dietary supplements you are taking,

as well as any recent laser or injection treatments.

In particular, if you bruise easily or are taking medication that may affect blood clotting, do not stop taking it on your own; discuss it during the consultation.

Rather than treating multiple areas at once, it may be more appropriate to take a step-by-step approach by selecting areas that match your current concerns and skin condition.

3) How does it differ from other injection methods?

Reedle Shot differs from manual injections in that it uses a device to inject into multiple points at consistent intervals.

Automatic injection may be used to treat a broad area evenly, but detailed adjustments are needed depending on the contours of the face and the location of blood vessels.

With manual injections, on the other hand, the medical professional can directly assess the skin thickness and injection points in each area and make detailed adjustments.

Rather than one method being superior, the appropriate approach varies depending on the ingredients used, the treatment area, and the desired care goals.

The approach to avoid is deciding to undergo treatment based only on the device’s name, without an explanation of the ingredients and injection depth.

A recommended approach is to check the skin thickness, blood vessel distribution, and history of previous treatments, then create a plan for each area.

4) How should you care for your skin after treatment?

After Reedle Shot, injection marks, redness, mild swelling, or bruising may temporarily occur.

The treated area may also look uneven or appear as though the ingredients have slightly collected in small areas.

Most of these effects settle over time, but the timing and degree of recovery may vary depending on the individual’s skin condition.

On the day of treatment, avoid applying strong pressure to the treated area or massaging it repeatedly.

Please also avoid activities that increase skin temperature and blood flow, such as saunas, heated spas, drinking alcohol, and strenuous exercise, for the period specified in your instructions.

The timing for washing your face and applying makeup may vary depending on the ingredients used and the injection depth, so please follow the post-treatment instructions first.

Maintain moisturization and use sun protection, but

it is advisable to postpone the use of highly irritating products, such as exfoliants and retinol, until the skin has calmed down.

If the pain gradually worsens, one side becomes severely swollen, or a warm sensation persists,

or if the skin becomes pale or turns blue,

contact the medical institution where you received the treatment immediately.

In closing

Reedle Shot Treatments: Differences Between an Automatic Injector and Manual Injections, and What to Know image 14

Reedle Shot is a treatment that uses an automatic injector to deliver selected ingredients to multiple points in the skin.

However, more important than the device itself is which ingredients are injected, where and at what depth they are injected,

and whether the treatment is suitable for your current skin condition.

This treatment is not necessary for everyone, and the number of sessions and intervals cannot be determined uniformly.

Before proceeding, fully check the product, injection method, recovery process, and warning signs, then determine whether the treatment is necessary through a medical consultation.

Frequently Asked Questions

Q1. Is Reedle Shot very painful?

As the needles repeatedly touch the skin, you may feel a prickling or pressing sensation.

The degree of pain varies depending on the area, injection depth, and individual sensitivity.

Q2. How long does bruising last after treatment?

Bruising and swelling may continue for several days, but the severity and recovery period vary from person to person.

If they progressively worsen or are accompanied by pain, please contact the medical institution where you received the treatment.

Q3. Is one treatment session enough?

The plan may vary depending on the condition of your skin, the ingredients used, and your care goals.

Rather than making a decision based on the response to a single treatment, it is better to determine the number of sessions and intervals after monitoring the progress.

Q4. What should I tell the medical professional before treatment?

Please provide complete information during the consultation about the medications and dietary supplements you are taking, any allergies and history of skin conditions,

and details of recent treatments.
