RTB Aesthetics is a doctor-led clinic in Cardiff, offering medical aesthetic treatments and medical weight management with a strong focus on safety, subtle results, and confidence that looks like you.
I’m Dr Roberta Barretto, an aesthetic doctor with 16 years of medical experience and 11 years’ registration with the General Medical Council (GMC). Alongside my aesthetics practice, I currently work as an Emergency Doctor in the NHS — a role that has shaped my approach to clinical care: calm, thorough, evidence-based, and always patient-first.
My approach
Aesthetic medicine should never feel rushed or “one size fits all”. Every face and every goal is different, so I take time to understand what you want to achieve, what will suit your features, and what will still feel natural in your day-to-day life.
My priority is to help you feel confident and healthy — whether that’s through subtle facial rejuvenation, skin quality treatments, or a structured, doctor-supervised plan for medical weight management.
From neuromodulator treatments and dermal fillers to advanced skin regeneration.
RTB Aesthetics offers a curated range of doctor-delivered options tailored to your concerns, your goals, and your lifestyle. Each treatment page explains what it is, who it’s for, expected results, downtime, and safety information — so you can make a confident, informed decision.
Anti-wrinkle
Anti-wrinkle injections can soften expression lines while keeping your face looking like you — just fresher and more relaxed. Treatment is always tailored to your anatomy and movement.
Dermal Fillers
Dermal fillers can restore balance, soften lines, and enhance features while still keeping results natural and proportionate. Treatment is guided by facial assessment, anatomy, and your preferences — not trends.
Skin Boosters
Skin boosters are designed to improve hydration, texture, and overall “skin quality” for a healthy-looking glow. They’re ideal if you want fresher skin without changing your facial features.
Medical Weigh Management
Medical weight management at RTB Aesthetics is a structured, doctor-led approach to supporting health, confidence, and long-term results. Your journey starts with a detailed medical consultation.
When you come to RTB Aesthetics, you can expect:
01 A medical consultation and assessment before any treatment plan is recommended
02 Honest advice, including when a treatment isn’t right for you
03 A personalised plan focused on balance, proportion, and natural results
04 A safe clinical environment, careful technique, and clear aftercare guidance
05 A professional, supportive experience from start to finish
Book a doctor consultation to discuss your goals, suitability, and a personalised plan — with no pressure and clear clinical advice.
You’ll be guided through treatment options, timelines, costs, and aftercare, so you can make an informed decision. Appointments are available in Cardiff.
