Reduced Side-Effect Risk by Excluding Steroids – AB Facial Contouring Injection

Contouring injections sound effective,but why do people hesitate?

When considering facial contouring injections, many people feel both excitement, “Will my face look slimmer?” , and anxiety, “What if I experience side effects?, In fact, some people hesitate after hearing experiences such as facial hollowing (fat atrophy), thinner-looking skin, or even changes in menstrual cycles following certain contouring injections. These concerns can make patients reluctant to proceed with treatment.


In this column, we’ll explain how contouring injections work, their effects and potential side effects, and what makes AB Facial Contouring Injection different.

How do contouring injections change facial lines?

Contouring injections are procedures designed to improve facial lines by reducing unnecessary fat layers or refining volume in the face.In cases where the lower face appears heavy, such as a double chin, jawline, or deep cheek fat (buccal fat), customized treatment in appropriate areas can create a smaller-looking face and a more defined contouring effect.


However, an important point is that “less facial fat does not always mean a more attractive result.”

Because the face is an area where even small changes are highly noticeable, outcomes can vary greatly depending on the injection ingredients, injection layer, dosage, and choice of treatment area.


In addition, when bone structure or muscle mass (such as the masseter muscles) plays a larger role, fat reduction alone may not produce the expected level of change. Identifying the underlying cause is essential. One of the main reasons contouring injection reviews vary so widely is that treatment often begins without confirming whether facial fat is truly the primary cause.

Contouring injection side effects such as facial hollowing and menstrual irregularities

The most concerning aspect of contouring injection side effects is not simple bruising or swelling, but changes such as a hollowed appearance of the face or deterioration in skin condition.

✔Facial hollowing · Indentation · An aged appearance

In some cases, reviews appear stating that the cheeks look sunken or the face appears older. This can occur when fat is excessively reduced or when certain ingredients trigger strong tissue reactions, leading to fat atrophy.

✔Skin thinning · Visible blood vessels · Redness

Especially with repeated procedures using formulations that include steroid components, or in individuals with sensitive skin, the skin may appear thinner or persistent redness may occur.

✔Menstrual irregularities and changes in overall condition (concerns about systemic reactions)

Reports of menstrual cycle changes after contouring injections are thought to be related to steroid components that may be included in some formulations. When absorbed into the body, these components may temporarily affect hormonal balance. As a result, ovulation timing or bleeding patterns may feel different from usual, with variations depending on treatment frequency, dosage, and individual sensitivity.


For this reason, reducing contouring injection side effects starts with clearly understanding and verifying the ingredients used.

A safe AB Contouring Injection excluding steroids, PPC, and hyaluronidase

AB Injection is AB Clinic’s signature contouring injection, developed with a proprietary formulation. While maintaining the effects of conventional fat-dissolving injections, it is designed to deliberately exclude ingredients that may cause concern.

  • ✔ NO steroids: Reduced burden of side effects such as skin thinning and hollowing, lower potential for hormonal changes

  • ✔ NO PPC: Reduced burden of strong irritation and inflammatory reactions

  • ✔ NO hyaluronidase: Reduced possibility of unnecessary tissue reactions

The most important point is that this approach does not stop at simply excluding ingredients that may cause side effects. The formulation is based on a special recipe developed by AB Clinic’s medical team through years of clinical experience, designed to maximize treatment effectiveness.

Even among contouring injections, results, safety, and effectiveness can vary greatly depending on the formulation and treatment design. AB prioritizes safety standards first, then maximizes effectiveness within those parameters.

AB Contouring Injection treatment interval

The treatment interval for AB Contouring Injection varies depending on individual fat thickness and contouring goals. Generally, a set number of sessions at two-week intervals is recommended, and appropriate spacing and cumulative planning are important.


Excessively aggressive fat reduction in pursuit of rapid results can increase the risk of hollowing or uneven texture, so a conservative approach is especially important for the face.

Techniques to prevent side effects

To reduce contouring injection side effects, the following factors are key.

  • ✔ Treatment area selection

    Areas with a high risk of hollowing are avoided or minimized

  • ✔ Layer control

    The closer the injection is to the surface, the higher the risk of unevenness or indentation

  • ✔ Dosage planning

    Planned, repeated treatments are more stable than a single excessive dose

  • ✔ Symmetry and balance

    Differences in left-right volume and facial muscle movement patterns are considered

  • ✔ Individual facial analysis

    Strategies vary depending on the proportion of fat, muscle, and skin laxity

Cases with high satisfaction in contouring injection reviews consistently involve accurate facial diagnosis and treatment carried out safely according to plan.

Recommended combination treatments with AB Facial Contouring

Facial contouring achieves higher completeness when skin elasticity (sagging) and jaw muscles (masseter muscles) are addressed together, rather than focusing on fat reduction alone. The representative synergy treatments with AB Facial Contouring Injection are as follows.

✔AB Facial Contouring Injection + Ultherapy


A combination that refines localized fat while simultaneously improving skin elasticity to create a firmer, more defined contour line.

✔AB Facial Contouring Injection + Jaw Botox

When a wide lower face is caused not only by fat but also by jaw muscles (masseter muscles), this combination can reduce muscle volume and help achieve a slimmer jawline.

AB Clinic’s solution for maintaining long-lasting contouring results

To maintain the effects of the AB Contouring Injection for a longer period, it is not enough to simply receive the injection; a system that also manages swelling, circulation, elasticity, and overall skin condition is required. At AB Clinic, dermatologists provide personalized post-treatment care plans tailored to each individual’s condition, helping facial lines settle more cleanly after the procedure.


Most importantly, AB Injection is not an undefined “cocktail injection” with unknown ingredients. It is based on a safety-focused design that excludes steroids, PPC, and hyaluronidase. Personalized formulations are built according to facial condition and areas of concern, reducing unnecessary risks.


If you are considering whether to undergo contouring injections, or which method would be safest, accurately analyzing the cause of your facial concerns should come first. Begin more safely with AB Clinic’s customized treatment design.
