There’s more to this breast augmentation than implants, It’s the finer surgical details that make the difference.

For this patient the surgical plan focused on increasing breast volume and projection while considering her existing breast shape, proportions and anatomical asymmetry.

Following a detailed assessment with Dr. Wessels, a breast augmentation combined with fat grafting was performed.

The surgical approach included Mentor implants, 330cc on both sides selected to increase fullness and projection.
Fat grafting using tissue harvested from the abdomen to assist with contour refinement & an internal bra technique to assist with implant positioning and support.

Her results highlight increased breast volume, greater projection and a change in cleavage and overall breast contour.

At One Cosmetic, every breast augmentation is individually planned with implant selection and surgical techniques guided by anatomy, clinical assessment and the patient’s goals.

Considering breast augmentation? Arrange a consultation with Dr. Wessels to explore your options.

One procedure, two surgical goals & a carefully considered approach.

For this 46 year old patient the surgical plan involved addressing both breast position and volume through a single stage breast lift and augmentation, also known as an augmentation mastopexy.

Dr Wessels combined a breast lift with 370cc Mentor MemoryGel Xtra round implants in a Moderate Plus profile. Her results highlight a higher breast position, increased upper pole fullness and a more rounded breast contour.

While combining a lift and augmentation into one operation may be appropriate for some patients, it is a complex procedure that requires careful surgical planning.

An important consideration is the potential need for revision surgery. Revision rates vary depending on several factors, including tissue quality, skin elasticity, wound healing, implant positioning, scarring and changes in breast tissue over time.

This is why a detailed consultation is essential. Considering breast surgery? Book a consultation at One Cosmetic to explore your surgical options and understand the benefits, limitations and risks involved.

For this 32 year old patient, the surgical approach involved more than increasing breast volume. It required careful consideration of her existing anatomy, natural asymmetry and desired proportions.

Following a comprehensive consultation, clinical assessment and 3D Vectra imaging with Dr. Wessels, Motiva Demi Ergonomix® implants were selected, with 320cc placed on the left and 340cc on the right to account for differences in her natural breast volume.

An internal bra technique was also utilised to assist with implant support and stabilisation of the breast fold. Fat grafting was incorporated to enhance the cleavage area and provide additional contour refinement.

At One Cosmetic, every surgical plan is guided by the patient’s anatomy, individual goals and clinical assessment, recognising that no two patients require exactly the same approach.

To learn more about breast surgery options, arrange a consultation with Dr. Wessels and our team.

From initial assessments and understanding available treatment options to recovery and long term wellbeing, our focus is on ensuring every patient feels informed, supported and cared for throughout their individual journey.

The part you can see is the excess skin. The part you can’t see is the muscle separation beneath it.

This patient presented with abdominal skin excess alongside muscle diastasis, so her surgical plan needed to address both.

Dr Louis Wessels performed an abdominoplasty, removing excess skin and repairing the muscle separation to support the abdominal wall and create a more defined abdominal contour.

The result shown highlights the change through the front and side profile, particularly across the lower abdomen.

Considering abdominoplasty? Your consultation is where we assess your skin, abdominal wall and individual anatomy to determine whether surgery may be appropriate for you.

This client completed a series of EMSCULPT NEO sessions with treatment focused on the abdominal area.

EMSCULPT NEO combines radiofrequency energy with HIFEM+ muscle stimulation to support muscle conditioning, reduction of fat in the treated area and non invasive body contouring.

In her photos you can see a visible change through the abdominal contour and definition following her treatment series.

It’s not about replacing movement, nutrition or a healthy lifestyle. It’s about adding another modality to the plan.
