“Blindness” and “necrosis”… What are the scary rumors you see online really like?💡

Many of you may be considering forehead hyaluronic acid injections because you admire a beautiful, softly rounded forehead contour, right?

But when you look into it, you may come across unsettling words such as “blindness,” “necrosis,” and “dangerous,”
making you wonder, “Maybe I should just avoid it after all…”😰

It is true that the forehead area has many blood vessels and is a site that should be treated carefully after understanding the risks.
At the same time, having risks does not mean it is necessarily dangerous.

What matters is receiving the treatment in an environment and with techniques that meet the conditions for enhancing safety.

This time, we will explain in an easy-to-understand way the main risks you should know about forehead hyaluronic acid injections, as well as the “5 conditions” to check for receiving the treatment more safely✨

😨 Why are forehead hyaluronic acid injections said to be “dangerous”?

First, let’s organize the reasons why forehead hyaluronic acid injections are viewed with concern.
Blood vessels connected to the area around the eyes, such as the supratrochlear artery and supraorbital artery, run through the forehead area.

If hyaluronic acid accidentally enters a blood vessel, a “vascular occlusion” may occur, obstructing blood flow.
Cases have also been reported in which this leads to skin problems or complications affecting vision.

However, these risks are not something that “happens to everyone”; they are greatly influenced by the technique, understanding of anatomy, and availability of emergency care.
In other words, it is important to correctly understand the risks and receive the treatment in an “environment with the proper conditions”💡

✅ 5 conditions for enhancing safety

From here, we will organize five points to check when choosing a clinic.

1️⃣ Is the doctor highly experienced in forehead injections?

The forehead is one of the more technically challenging areas.
Make sure the doctor understands facial anatomy, including the course of blood vessels and tissue layers, and has sufficient experience with forehead hyaluronic acid injections.

During the consultation, it is reassuring if you can ask questions such as:
・Will the assigned doctor perform the procedure?
・What experience do they have with forehead injections? (Case trends and explanations of how complications are handled)

2️⃣ Are products from authorized distribution channels used?

The quality of the product is directly linked to safety.
Confirm that the clinic uses approved products handled by medical institutions and obtained through authorized distribution channels.

※ To avoid misunderstandings, it is safer to present brand names as “examples.”
(Examples: ジュビダーム／レスチレン, etc.)

3️⃣ Does the clinic follow a policy of “adjusting gradually with small amounts”?

A policy of injecting a large amount all at once requires caution from both risk and aesthetic perspectives.
When safety is prioritized, an important point is whether the clinic proposes adjusting gradually with small amounts and, if necessary, dividing the treatment into multiple sessions.

If a clinic strongly recommends options such as “unlimited injections” or “the maximum amount in one session,” consider them carefully⚠️

4️⃣ Can they explain the injection layer, direction, and speed?

To reduce risks, it is important to consider which layer to inject into, from which direction, and at what speed.
During the consultation, check whether they can “explain their approach in words.”

(Examples)
・Being mindful of injecting into the appropriate layer
・Not forcing the product in under excessive pressure
・Injecting slowly in small amounts, etc.

※ Since the effectiveness of an “aspiration test” in clinical settings is still debated, it is recommended not to state it definitively as an “essential condition,” but to present it only as an example of an explanation.

5️⃣ Is the emergency response system clearly established?

In the unlikely event of a vascular complication, the “initial response” is crucial.
Confirm whether the clinic has a system with emergency procedures, including the use of hyaluronidase (dissolution), and can explain them.

・Keep dissolving medication on hand
・Emergency contact procedures
・Response time when abnormalities occur after the procedure
Having these details clearly established can provide peace of mind.

⚠️ Be Cautious of Clinics Like These (4 Warning Signs)

❌ The price is extremely low (the reason is unclear)
❌ The consultation is too short (no examination or risk explanation)
❌ The risk explanation consists only of “It’s fine” and lacks specifics
❌ Strongly encourages large-volume injections or “unlimited injections”
