Hatate, Ariko

As a plastic surgeon, I have gained extensive experience through numerous cases, cultivating precise techniques and a deep understanding of anatomy. Currently, I combine plastic surgery expertise with the latest techniques to provide aesthetic medicine addressing aging concerns like skin, contours, and sagging. "Natural beauty" isn't about doing nothing and leaving it to chance; it lies beyond the will to choose how you want to be. My experience as an idol during medical school made me realize the power appearance holds over the heart, and I focus on supporting patients in achieving "days where they can like themselves more." I also offer consultations in English and prioritize creating a comfortable environment for open discussion.

Hello, everyone!

↓I previously wrote an article about hyaluronic acid injections for the nose.

Hyaluronic acid injections are an excellent treatment that, when used effectively, can deliver highly satisfying results in a short amount of time.

Even so,

"It might look unnatural," "It gets absorbed quickly," "I'm afraid of allergies."

Many people hold that image.

However, thanks to advancements in technology, hyaluronic acid injections have become safer and more stable.

“Safe, natural, and long-lasting hyaluronic acid is available.

That is, thisNeauviais.

 


 

 Limitations of Conventional Hyaluronic Acid

 

General hyaluronic acid is "BDDE (Butanediol Diglycidyl Ether)The molecules are linked together using a chemical crosslinking agent.

 

This structure has a proven track record and high safety standards, but

 ・Prone to denaturation by heat (HIFU, RF, etc.)

 ・Prone to degradation by oxidative stress

 ・There were issues such as inflammation or delayed nodules occurring in rare cases.

 

"After getting hyaluronic acid injections, I feel like my hyaluronic acid levels have decreased."

"After a while, I felt a lump-like discomfort."

Such feedback may also be a reaction stemming from this structure.

 


 

 Why Neauvia is Chosen

 

Neauvia is a “next-generation filler” with a structure completely different from conventional hyaluronic acid.

✅ Feature 1: High safety due to PEG crosslinking

The most distinctive feature of Neauvia isPEG (Polyethylene Glycol) Crosslinkinga special structure.

PEG is also used in pharmaceuticals and vaccines.Biocompatible materialsis.

 ・Less likely to cause allergic reactions

 ・Immune reactions such as inflammation and nodules are extremely minimal

 ・The breakdown products are stable and distribute uniformly throughout the body.

 

In fact, a 2021 three-year follow-up study by Rauso et al. found that after using PEG-crosslinked hyaluronic acid fillers,No granulomas or foreign body reactionsIt has been reported.

✅ Feature 2: Heat-resistant and compatible with HIFU and RF treatments

Neauvia is highly heat-resistant.

Unlike conventional BDDE-crosslinked fillers, it possesses a structure that is resistant to denaturation and absorption by the thermal energy of HIFU or RF.

In other words──

"You can't get HIFU after getting hyaluronic acid injections."

A filler that defied conventional wisdom.

In fact, in my clinical practice, even when performing HIFU or Thermage after Neauvia injections, there is almost no change in volume or disruption in texture.

Polimeni et al., Journal of Cosmetic Dermatology, 2024(It was reported that even after heat treatment, there was little change in shape or density.)

 

✅ Feature 3: Natural and elegant finish

Neauvia has a uniform gel structure and blends very naturally with the skin.

Minimizes stiffness and discomfort during movement while maintaining beautiful facial expressions,

Restore plump contours and firmness.

 

✅ Feature 4: High Durability

Clinically, it also has excellent durability,

Depending on the partNatural volume lasts for about 12 to 18 monthsI will do so.

It absorbs evenly over time, so it's less likely to lose its shape.

Efficacy and Safety of Neauvia Intense, PMC11178092, 2024No adverse events, high satisfaction, and long-term stability have been confirmed.

 

🌿 Recommended for those who...

 ・Want to look younger naturally

 ・I don't want to end up with an unnatural "hyaluronic acid face"

 ・I want to continue HIFU and RF treatments while maintaining my care routine.

 ・Safety is our top priority

Summary: Neauvia is a "gentle yet powerful" hyaluronic acid.

Hyaluronic acid now comes in a truly diverse range of types and prices.

But once you know how it's made, the difference is clear.

 

Neauvia is,

🔹 Gentle on the body (safe)

🔹 Natural (elegant) even in motion

🔹 Heat-resistant (long-lasting)

For those who prioritize self-care, this hyaluronic acid is perfect—a choice you can trust for your body's well-being.

To preserve beauty for longer, with peace of mind.

I confidently recommend Neauvia.
