This page summarizes basic knowledge about beauty hyphenation and the types of devices. Although the HIF has been attracting attention for its high effectiveness, we sometimes see negative information such as "you should stop" and "it makes you sag easily" in wisdom books and blogs. We will therefore provide a thorough explanation of the truth behind the rumors. We also introduce some precautions to avoid mistakes with HIF, so please refer to this page if you are curious about the beauty HIF procedure.
What is Hyf (HIFU) used in cosmetic medicine?
顔のリフトアップ効果や引き締め効果が得られる美容施術として「効果がすごい!」と注目されているハイフ。まずはハイフについて、基本的な知識をおさらいしていきましょう。
What is a hyphen?High-density focused ultrasound therapyHIFU is an abbreviation of "High Intensity Focused Ultrasound", which stands for "High Intensity Focused Ultrasound". Literally, by applying high-density ultrasound, the skin is intensively irradiated deep into the skin without damaging the skin's surface. In the tissues inside the skin that receive the heat, the process of healing damage promotes the production of elastin and collagen, resulting in positive cosmetic effects.
Effects of hyphae used in cosmetic medicine
Specifically, the cosmetic effects of HIF include the following
- Improvement of sagging facial lines
- Improvement of laugh lines
- Skin texture improvement through skin tightening
- Wrinkle Improvement
- Partial slimming effect
The HIF uses high-density ultrasound waves to remove fat from the subcutaneous fat layer, which lies further beneath the skin.Even the SMAS layer can be approached.という点が大きな特徴です。SMAS層は肌の土台部分にあたり、皮膚を支える役割を果たしています。しかし、SMAS層はおもにコラーゲンで形成されているため、加齢でコラーゲンが減少することで緩みが生じ、肌表面のたるみにつながるのです。
これまで、このSMAS層に働きかけるためには、フェイスリフトのようなメスを使った治療が必要でした。しかし、ハイフが登場したことで、外科的手術を施さなくてもSMAS層に直接作用できるようになり、肌内部からハリを与える高いリフトアップ効果が得られるようになったのです。
Who is likely to benefit from HIF?
As we age, we may experience a variety of problems, but the following conditions can be expected to improve with hyphrotherapy.
- I'm over 35 years old and my face is sagging.
- I feel that my skin has lost its elasticity and wrinkles are becoming more noticeable.
- I want to reduce fat such as double chin and sides of the mouth and lose some weight.
- I want to improve my laugh lines and marionette lines.
Many people in their mid-30s begin to notice sagging and wrinkles. In particular, fine lines and sagging skin around the eyes are areas where the lifting effects of HIF can be easily felt.
Types of hyphens used in cosmetic medicine

There are many different types of hyphae. Let's check out the different types of hyphens used in cosmetic medicine.
The type of hyphae depends on the layer to be approached.
There are three different irradiation methods for the same hyphae, depending on the device and mode. Each irradiation method approaches different layers and has the following characteristics.
| Types of Hyphens | feature |
| dot-haif | ・点で焦点を合わせるメジャーな照射方法
・緩んだSMAS層のリフトアップ効果がある |
| linear HIF | ・線状に焦点を合わせる照射方法
・広範囲で脂肪細胞を破壊できるので部分痩せに効果的 |
| hyphenated shower | ・皮膚の表層にアプローチするので効果がすぐ現れる
・毛穴の引き締めや肌質改善に効果的 |
Types of hyphae equipment often used
The following is a list of common hyphenated devices commonly used in beauty clinics. Since the characteristics and what can be handled differ depending on the equipment used, it is a good idea to be aware of the equipment used when selecting a clinic.
| Type of equipment | irradiation range | Duration of effect | feature |
| Ulthera (treatment for arthritis) | one's whole face | 1 to 1.5 years | Highly effective lifting effect approved by the U.S. Food and Drug Administration (FDA) |
| doubled gold | Whole face and body | 3 to 6 months | Quick-acting, painless, and quick treatment |
| Ultraformer MPT | Whole face and body | 6 months to 1 year | Pen-type cartridge allows you to approach fine areas around the eyes, such as sagging and fine lines and wrinkles |
| Son Queen | one's whole face | 3 to 6 months | Less pain and less downtime, suitable for beginners of HIF |
| Third Generation Titan | one's whole face | 3 to 6 months | ・皮膚の引き上げや引き締めに効果的
・治療時間の短縮が可能に |
| superhigh frequency | one's whole face | 6 months to 1 year | Dense thermal energy produces a powerful lifting effect |
Different types are available for different parts of the body to be treated.
As described above, there are various types of HIFs with different devices and irradiation modes, but the types also differ depending on the area to be approached. For example, vaginal hyphae are used to improve urinary leakage and vaginal tightening, and hyphae around the eyes are used for a wide range of treatments and problems.
Why do people say, "You shouldn't do hyph?"

On the Internet, I see blogs that say, "I regretted taking the hyphen," and wisdom posts that say, "Should I stop taking the hyphen?" and "Should I stop having a hyphen? Are there any disadvantages or future risks to hyphenation? Let's take a deeper look into the reasons for the negative impression.
Many accidents caused by esthetic hyphae
In the past, it was possible to receive the Hyf treatment at esthetic salons other than beauty clinics. However, there were frequent accidents such as burns after the esthetic hyphu treatment, causing the skin to wrinkle and sag, and so on. As a result, starting in June 2024, the hygienic treatment should be performed by a physician at a medical facility.The Medical Practitioners Act was decided to be applied.されました。
費用だけを見るとエステハイフを選びがちですが、10年後も残るような後遺症になってしまう恐れもあります。そのため、施術前に医師がカウンセリングを行う美容医療クリニックで、ハイフの施術を受けるようにしましょう。
There are rumors that hyphens can cause cancer.
Many people may be concerned because there are rumors on the Internet that "hyphenation causes cancer" and "I got tongue cancer after receiving treatment with Ulthera. However, all of these are information spread by speculation and have no scientific basis at this time. On the contrary, the HIF device itself is sometimes used in the treatment of prostate and pancreatic cancer, and this may be the connection between "cancer" and "HIF.
There are some examples of hyphenated failures.
Even when a patient undergoes a hyphenation procedure at a cosmetic clinic, there are not always cases of failure. In particular, the cases that are most likely to be considered failures are those in which the effects of the treatment are not seen. In particular, it tends to be difficult to feel the effects when there is swelling during downtime or when there is little sagging or fat to begin with.
What to Expect When Receiving Hyphenation in Cosmetic Medicine

In order to avoid making mistakes in the HIF, keep the following points in mind
- Know about downtime and side effects.
- Thorough aftercare after the procedure.
- Some people can't take the hyphen.
- Receive hyphenation at a medical institution.
甲状腺や心臓に疾患がある人や妊娠中の人はハイフを受けるべきではありません。このような注意点も踏まえて、事前にしっかり説明してくれるクリニックを選ぶと、トラブルが避けられるでしょう。
