Possessing an international perspective—evidenced by invitations to present at overseas conferences—I actively promote techniques as a Key Opinion Leader (KOL) for GOURI and REJURAN®. My specialty procedures include double eyelid surgery, skin-nurturing boosters, and body hyaluronic acid treatments. My approach leverages the holistic understanding of the body cultivated through internal medicine to guide patients toward natural, healthy beauty.

ベビーコラーゲンとは?効果や特徴をBIANCA CLINICが解説

 

Baby Collagen is a treatment in which a human-derived collagen preparation is injected into the skin to address fine lines, dark circles, and skin firmness.
 

During consultations, I often hear patients say things like, “I’m concerned about the fine lines around my eyes, but I don’t really understand the difference between this and hyaluronic acid,” or “I’m worried that having it injected around my eyes will look unnatural.”

 

Baby Collagen is a treatment in which a human-derived collagen preparation is injected into the skin to improve skin firmness and smoothness. In this article, we’ll summarize the characteristics, expected results, and precautions regarding Baby Derm and Collagen Boost—two treatments we offer at our clinic—based on the information we provide during consultations.

What kind of treatment is Baby Collagen?

Baby Collagen is a procedure in which a human-derived collagen preparation is injected to smooth out fine lines around the eyes and mouth, where the skin is thin.

How Baby Collagen Works

Baby Collagen is a treatment in which a formulation containing Type I collagen—which supports the skin’s structure—and Type III collagen—which is said to be abundant in a baby’s skin—is injected into the skin. This Type III collagen is why the treatment is called “Baby Collagen,” and, together with Type I collagen, it plays a role in maintaining the skin’s flexibility and firmness.

 

This treatment aims to smooth out fine unevenness and fine lines by replenishing collagen in skin that changes with age.

 

While hyaluronic acid injections are often used to add volume to hollows and facial contours, baby collagen is typically a better option for injections into the skin’s superficial layers or thin areas. Understanding this difference will help you determine which treatment is better suited to your specific concerns.

What Is Babyderm?

Babyderm® is a human-derived formulation containing Type I, III, and V collagen. Because it is non-crosslinked, has low viscosity, and blends easily into tissues, it can be injected in small amounts even into areas with thin skin, such as around the eyes and mouth.

 

Each type plays a specific role: Type I provides the foundation of the dermis, Type III ensures tissue flexibility, and Type V supports the structure of collagen fibers. This formulation is best suited for those who want to naturally refine their skin texture and minor unevenness rather than add significant volume.

 

However, when injecting into thin areas, even slight differences in volume or depth can directly affect the final result. We determine the injection method only after thoroughly assessing the thickness of the skin and the degree of indentation during the examination.

What Is Collagen Boost?

Collagen Boost is a unique injection treatment developed by our clinic that combines baby collagen with the “Hydro” skin-rejuvenating injection. It is designed for patients who wish to address multiple concerns simultaneously, such as dryness, fine lines, and loss of firmness.

 

During the procedure, we adjust the injection volume, depth, and angle while assessing your skin condition and the overall balance of your face. If you wish, we can also use the VISIA® skin analysis system to evaluate your skin condition before and after the procedure.

 

Rather than making a decision based solely on the name of the product, we place great importance on determining whether the underlying cause of dark circles and fine lines is suitable for this treatment.

What benefits can I expect from baby collagen?

Baby Collagen is expected to be effective in reducing fine lines around the eyes and mouth, improving skin firmness, and reducing dark circles caused by thin skin or sunken areas.

The following are some of the changes you can expect from baby collagen.

  • Smooths out fine lines around the eyes and mouth
  • Reduces the appearance of dark circles caused by thin skin or slight hollows
  • Restores firmness and elasticity to the skin
  • Smooths out fine irregularities such as nasolabial folds and marionette lines

 

The skin around the eyes is naturally thin, making it prone to fine, crepe-like wrinkles even with slight dryness or a loss of elasticity. By injecting small amounts into the superficial layers, we aim to restore thickness and firmness from within the skin, resulting in a smoother surface.

 

When it comes to dark circles under the eyes, this treatment may not be equally effective for all types. It may be a viable option for dark circles caused by thin skin or shallow hollows, but if pigmentation or significant sagging is the primary cause, a different treatment may be more appropriate.

 

Another goal is to provide long-term support for skin health and the body’s natural collagen production. That said, we’d like to note in advance that the nature of the changes and how long they last may vary from person to person.

 

Rather than simply choosing a treatment based on its name—such as “Baby Collagen for Under-Eye Bags”—I believe that examining the thickness of the skin, the degree of hollowness, and the overall balance of the face during a consultation is the surest way to achieve a natural-looking result.

What are the pros and cons of baby collagen?

While baby collagen blends well into thin areas of the skin, it carries risks such as swelling, bruising, unevenness, and infection.

Benefits of Baby Collagen

  • It is easy to inject into areas with thin skin, such as around the eyes and mouth
  • It makes it easy to achieve a natural finish that blends seamlessly with your skin
  • Targets fine lines and uneven skin texture
  • This can be considered as a treatment to improve skin firmness and overall condition
  • Compared to animal-derived products, it is an option designed with allergic reactions in mind.

 

Babyderm is a formulation with low viscosity that makes it easy to inject in small amounts into the superficial layers of the dermis. Even in areas with thin skin, such as around the eyes, treatments can be tailored to smooth out the skin’s texture rather than drastically altering its shape.

 

Products derived from human placenta are said to have a composition similar to that of collagen found in human skin. However, just because a product is of human origin does not mean it will not cause allergic reactions or foreign body reactions. Be sure to inform your doctor of your medical history and any allergies before undergoing treatment.

Disadvantages of Baby Collagen

  • Swelling, redness, pain, needle marks, and bruising may occur.
  • Results and duration may vary from person to person.
  • For deep wrinkles and large indentations, a single treatment may not produce sufficient results.

 

If too much filler is injected, swelling and unevenness become more noticeable; if too little is injected, the results are less noticeable. Since the skin around the eyes is particularly thin, determining the appropriate depth and amount is crucial to the final result.

 

After the procedure, you may experience temporary swelling, redness, pain, needle marks, or bruising. Although rare, complications such as infection or vascular embolism cannot be ruled out. If you notice any concerning symptoms after the procedure, do not ignore them; contact the medical facility where you received the treatment as soon as possible.

Q. How long do the effects of Baby Collagen last?

A. The duration of results varies from person to person. We generally advise that Babyderm lasts approximately six months to one year. Since this can vary depending on the injection site, the amount injected, and the condition of your skin, we will explain this in detail during your consultation.

Q. When can I start wearing makeup or taking a bath after the treatment?

A. Provided there are no complications, you may apply makeup starting the same day, avoiding the injection sites. As a general guideline, you may take a shower on the same day, but should wait until the following day or later to take a bath. Since this may vary depending on the specific treatment, please follow the post-treatment instructions provided.

Q. Please tell me about the risks and side effects of baby collagen injections.

A. Possible side effects include swelling, redness, pain, bruising, unevenness, lumps, and infection. Additionally, if a product derived from human placenta is used, you will not be able to donate blood after the procedure; therefore, please review the precautions before treatment.

Q. How much do baby collagen injections cost?

A. The cost varies depending on the product used, the volume injected, the injection site, and the service fee. Additional charges for the product and the service fee may apply, so please check the latest pricingTreatments PageorSchedule of ChargesPlease confirm this during your counseling session.

Q. What is Collagen Boost?

A. This is BIANCA’s proprietary injection treatment that combines Baby Collagen with the “Hydro” skin rejuvenation injection to address multiple skin concerns, such as dryness, fine lines, and loss of firmness.

Because the eye area is so delicate, it’s important to identify the “cause” before using any treatment.

Baby Collagen is a procedure that involves injecting a human-derived collagen preparation to smooth out fine lines around the eyes and mouth, improve skin firmness, and even out minor skin irregularities. While it blends well even in thin-skinned areas, please be aware in advance that there are risks such as swelling, bruising, and unevenness.

 

To achieve natural-looking results, it’s essential not only to choose the right product but also to undergo a consultation to identify the cause of your concerns and determine the appropriate injection volume.

 

At BIANCA CLINIC, we assess your skin condition and the overall balance of your face before recommending a treatment. If you’re wondering whether Baby Collagen is right for you, please schedule a consultation to discuss your options.
