YBC London's founder and lead clinician: Yildiz Costi is recognised as a leader in natural-looking aesthetics and non-surgical enhancements.

With over 30 years experience, her expertise, artistry and commitment to patient care have made her one of the most respected names in the industry.

A mission to empower:

For Yildiz, aesthetics is about more than appearance. It’s about empowering people to feel truly confident in their own skin.

Her mission is to help patients feel happy, comfortable and authentically themselves, whatever their starting point or story.

Yildiz often works with individuals who have experienced trauma, weight loss, or scarring, using her skill to restore their appearance so it reflects their inner self more accurately. This compassionate, restorative approach is at the heart of her practice.

A global educator and innovator

Alongside her clinical work, Yildiz is a qualified lecturer (Cert Ed) and qualified assessor (TAQA), teaching and training doctors around the world in her renowned techniques.

Her reputation for combining the latest treatments with the highest standard of care has set a benchmark for safe, natural, and patient-focused aesthetics.

Confidence through care

Yildiz’s philosophy is simple: aesthetic treatments should enhance not “change”. Through her work, she has helped countless patients achieve results that feel natural, restoring not only their appearance but also their confidence, wellbeing and sense of self.


At YBC London (previously Yildiz Beauty Confidence), we believe that real beauty confidence begins with feeling your best.

Do aesthetic treatments hurt?

Whilst some aesthetic treatments, such as injections may be slightly painful from time to time, we always take great care to ensure a comfortable experience for every patient. By combining Yildiz's meditative breathing techniques, tension balls and numbing cream, the YBC London team always ensures every treatment avoids 'pain' as much as possible.

Whilst everyone's pain tolerance is different, many customers have likened the discomfort felt in treatments to a long waxing session or being 'pinched'.
Do I need a prescription for anti-wrinkle (aka "botox") injections?

According to UK regulations, any patient receiving botulinum toxin injections must hold a valid prescription. YBC London is partnered with NextGen Pharma, meaning we can offer in-house prescription clinics to all patients, for a fast, safe and fully-regulated prescription should this treatment be right for you.
