Billie get a luxury Manicure and Pedicure
Duquessa hosted the cast and crew of Offspring as they filmed Billie enjoying a luxury manicure and pedicure as part of the season opener of Offspring.

An effective cosmetic beauty tool, anti-wrinkle injections produce marked results when applied professionally by the fully trained staff at the Duquessa Anti-Ageing Clinic.

Restrictions set by the Australian Therapeutic Goods Authority (TGA) mean that we cannot name the anti-wrinkle injectable we use, but you will certainly recognise its widely used trade name. The treatment leaves skin looking rejuvenated and refreshed so you can feel confident and secure.

Dermal fillers are widely recognised as one of the best ways to improve the shape of your face without surgery. Dermal filler gel is injected into the problem area to reduce the wrinkle depth.


Is your skin not as firm as it used to be? If you want to effectively combat the signs of ageing or weight loss, Thermage is one of our most tried and tested skin tightening treatments.


Also known as a “Vampire Facial” or “Blood Facial”, Platelet Rich Plasma (PRP) therapy is used to improve skin tone, texture and elasticity.


OmniluxTM uses a combination of pure, visible red and infra red light to stimulate the deeper skin tissue, leading to a softening of fine lines, improved skin tone and super smooth skin.


Colonic hydrotherapy is a safe and gentle technique used for the colon’s cleansing, which in turn, is beneficial to the whole body.


Some of the specific benefits people may experience include increased energy, enhanced mood, improved sleep, decreased stress and anxiety, increased immunity, hydration, and muscle recovery.


Dull, damaged, dry or lifeless skin will become revitalised and radiant after a medical peel.

Road test This week I try ... eye Thermage The lowdown It's been a while since my last painful procedure, so here I am with therapist Georgie, who will give a lift to my tired-looking eyes with radio frequency based Thermage. This procedure helps to tighten skin and reduce both wrinkles and eye hooding. Georgie begins by placing a grounding pad on my back. She then administers anaesthetic eye drops and places a black shield (similar to a contact lens but less comfortable) over my eyeballs. She runs the Thermage wand over my eyelids and around my orbital bone and, via my feedback, gauges how much pain I can withstand. The process is repeated on the other eye and then she switches to a larger treatment head that she runs over the area above my brows and the top of my cheeks. Pain factor On some sensitive spots it feels like a small electric shock. Not nice. Downtime 45 minutes. Results The next day my lids look lifted, a result which will improve over the next six months. I can't wait.
