Winter can leave skin feeling dull, dehydrated and lacking its usual radiance.

This client visited Dermal Therapist Christie looking to rejuvenate her complexion & address the dryness she had been experiencing as the season changed. As she was pregnant, her treatment was carefully curated to suit her individual needs.

The result? Skin that looks brighter, more hydrated and visibly rejuvenated immediately after treatment.

Your skin changes with the season which is why every appointment begins with a thorough consultation and skin assessment. From there our team can recommend treatments and home care tailored to your skin concerns & goals.

If your skin has been feeling the effects of winter now is the perfect time to book a consultation with our dermal team.

Your passport is ready & your wardrobe is planned. Your skin deserves the same consideration.

That’s why timing matters.

This guide explores how different treatment options may fit within your travel timeline, helping you approach your departure feeling prepared, informed and considered.

Because exceptional skin rarely begins at the airport.

Arrange a consultation with our team to discuss your concerns, travel dates and treatment suitability.

The best implant size is the one that works with your anatomy.

This 20 year old patient wanted to increase breast fullness while maintaining proportions that complemented her frame and natural shape.

Breast surgery is about more than implant size alone. In this case implant selection, positioning and support were all carefully considered during the planning process.

Her surgical plan included:
Motiva Ergonomix® implants.
375cc for both sides.

An internal bra technique was incorporated to provide additional structural support, while fat grafting was used to create a harmonious transition tailored to the patient’s anatomy.

Considering breast surgery? A consultation is the first step, please book via the link in bio or speak to our team.

Significant weight loss can change more than just the number on the scale.

This 37 year old patient presented following weight loss after gastric sleeve surgery with concerns relating to breast position and excess abdominal skin.

Following a comprehensive consultation and clinical assessment with Dr Louis Wessels, a personalised surgical plan was developed. Treatment included a breast lift and abdominoplasty (tummy tuck), tailored to the patient’s anatomy, skin quality & individual goals.

No two patients are the same. Factors such as tissue characteristics, previous weight changes and overall body proportions all play an important role when planning surgery. For this reason, every treatment plan begins with a detailed consultation and thorough assessment.

If you are considering surgery following significant weight loss, a consultation can help you understand the options available and whether they may be appropriate for your circumstances.

To book your consultation please follow the link in bio or reach out to our team.

As we move into the cooler months many people begin planning treatments that are best suited to winter skin. And this year there’s something new at One Cosmetic.

Excel V+ is an advanced laser that works to target concerns such as visible vessels, diffuse redness, rosacea prone skin, pigmentation and overall skin quality.

Rather than focusing on a single concern, treatment recommendations are guided by a comprehensive assessment of your skin, goals and clinical needs.

Because clearer looking skin isn’t always about treating one thing. It’s about understanding the bigger picture.

To learn whether Excel V+ may be suitable for you, arrange a consultation with our team today.
