What Is Hydro Boost? An Explanation of Its Expected Effects, Benefits, and Drawbacks

My journey into aesthetic medicine stems from a desire to help enrich and beautify lives beyond simply treating illness. My specialties include hyaluronic acid, Botox, and thread lifts. I provide treatments that enhance each individual's unique qualities and bring out an elegant, natural beauty. For concerns around the eyes that are difficult to improve with dermatology alone, I also perform surgical procedures. By integrating dermatology and surgery, I holistically balance the entire face. With three periods of overseas study, I am also able to provide consultations in English.

Hydro Boost is a skin-nourishing injection that features a proprietary blend of hybrid hyaluronic acid, botulinum toxin, and other ingredients. It is designed to improve the skin’s moisture levels and firmness.

 

“I’m moisturizing, but my skin still feels a little dry,” or “I feel like my cheeks have lost some of their firmness compared to before.” I often hear these kinds of concerns during consultations.

 

In this article, we’ll introduce the Hydro Boost treatment offered at BIANCA CLINIC as one option for addressing dry skin and loss of firmness.

 

This treatment works to improve skin condition from the inside out by delivering multiple skin-nourishing ingredients deep into the skin. I’d like to explain everything—from how it works and the ingredients used to the expected results and important precautions—as clearly as possible.

What Is the Hydro Boost Treatment?

Hydroboost is a skin rejuvenation treatment that involves the precise injection of the formulation from the epidermis into the dermis.

 

Its fundamental purpose differs from that of standard hyaluronic acid injections, which are designed to create contours and add volume. Hydro Boost focuses not on “shape” but on “texture”—the skin’s actual condition, such as hydration, firmness, and smoothness. Because it delivers beauty-enhancing ingredients directly to the skin, it is particularly effective at addressing multiple concerns simultaneously, such as dryness and loss of firmness.

Our Clinic’s Original Formula

Our clinic’s Hydro Boost is an original skin-nourishing formulation based on “Hydro” and a botulinum toxin preparation.

 

Hydro is a hybrid formulation that combines three types of hyaluronic acid with different molecular weights. Rather than simply adding volume to and reshaping the skin, it is used to improve skin condition by leveraging its ability to support moisture retention and skin elasticity.

 

▶Regarding Hydro,Treatments PageHowever, we've provided a detailed explanation, so please be sure to check it out as well.

 

Botulinum toxin formulations are designed to target sebum secretion and the appearance of pores by injecting small amounts into the superficial layers of the skin. In addition, depending on your skin condition and preferences, we may combine these with exosomes or human stem cell culture supernatant.

Manual Injection by a Physician

HydroBoost is injected manually by a doctor, who monitors the condition of your skin as they work. Since skin thickness and concerns vary depending on the area—such as the forehead, cheeks, around the eyes, around the mouth, and the neck—manual injection allows for precise, on-the-spot adjustments to the injection volume and needle depth.

At our clinic, we begin by carefully assessing the condition of your skin and listening to your preferences during the consultation. We then work with you to determine whether the treatment is appropriate for you in the first place and what combination of treatments might be best suited to your needs.

Benefits You Can Expect from Hydro Boost

Hydro Boost is expected to help improve the skin's moisture, firmness, and radiance, while also addressing fine lines and the appearance of pores.

 

The following are some of the benefits I often discuss with patients during their appointments.

  • Approaches to Dryness and Lack of Moisture
  • Improved firmness and elasticity
  • Reducing the Appearance of Fine Lines
  • Reducing the Appearance of Enlarged Pores
  • Inhibition of sebum secretion
  • Improved overall skin smoothness and texture

Moisture and firmness for dry skin

Hydro contains three types of hyaluronic acid with different molecular weights as its main ingredients and has excellent moisture-retaining properties. By injecting it into the skin, it helps restore moisture to skin prone to dryness, aiming to give it a plump, supple appearance.

 

As your skin's moisture levels balance out, you can expect that fine lines and uneven texture—which were more noticeable due to dryness—will become less of a concern than before.

Smooths away concerns about pores and excess oil

It is believed that injecting a small amount of botulinum toxin into the superficial layers of the skin can help reduce sebum production and tighten pores.

 

This treatment differs from standard botulinum toxin injections for expression lines in both the layer into which it is injected and its intended purpose. It might be easier to understand if you think of it as similar to “skin Botox.” Rather than directly addressing deep wrinkles, this procedure aims to create a smoother, more toned appearance on the skin’s surface.

You can adjust the formula to suit your specific concerns

One of the key features of this treatment is the ability to customize the formulation—such as by combining exosomes and human stem cell culture supernatant—based on the condition of your skin. For those with multiple skin concerns—such as dryness, loss of firmness, lack of radiance, and visible pores—we recommend a customized formulation based on the results of your consultation.

 

However, there’s one thing I’d like to point out: it’s not necessarily true that the more ingredients you use, the more effective the treatment will be. We believe that carefully assessing the cause of your concerns and the condition of your skin—and then selecting the appropriate ingredients and treatment methods—will ultimately lead to greater satisfaction.

Advantages, Disadvantages, and Side Effects

While this treatment is effective for addressing a variety of skin concerns, as it involves injections, there is a possibility of pain, redness, swelling, or bruising. We’ll explain not only the benefits but also the precautions you should be aware of.

Benefits

  • Makes it easy to address multiple skin concerns at once
  • You can adjust the combination of formulations to suit your skin condition.
  • Since it is entered manually by a doctor, it is easy to make detailed adjustments for each body part.
  • Treatments can be performed not only on the entire face, but also around the eyes, mouth, and neck.
  • The goal is to refine the skin's texture without significantly altering its shape.

 

I feel this treatment is an especially good option for those dealing with multiple concerns, such as dryness, loss of firmness, visible pores, and fine lines. Since a doctor administers the injections by hand, it’s easy to adjust the treatment to suit the skin’s thickness and specific concerns—even in delicate areas like around the eyes and mouth—which is a definite advantage.

 

Another feature of our clinic is that we can customize our original blend formulations based on the results of your examination.

Disadvantages and Side Effects

  • You may feel some pain when the needle is inserted.
  • Redness, swelling, edema, and bruising may occur.
  • Hives or swelling may occur
  • Immediately after the injection, a slight, bumpy swelling may remain temporarily.
  • Results may vary from person to person, as may the number of treatments required.

 

Redness and swelling after the injection usually subside within a few hours to about two days. As for swelling at the injection site, it may last about 3 to 4 hours on the face and from the next day through 2 to 3 days on the neck.

 

During the procedure, we use fine needles and incorporate topical anesthesia, nerve blocks, and cooling to minimize discomfort. However, I would like to be honest with you and say that we cannot guarantee that you will feel absolutely no pain.

 

The severity of side effects and the time required for recovery may vary depending on your skin type and the injection site. If you experience persistent severe swelling or pain after the procedure, do not try to self-diagnose; instead, consult the clinic where you received the treatment.
