About Bubbles

After years in accounting Nobubelo realised she cared more about people than spreadsheets. What started as an interest in skin and how the body works became something bigger a way to help people actually feel good about themselves again.

At The Sigma Clinic, every appointment starts with a proper conversation. Skin consultations aren’t just a box to tick they’re where everything begins. Whether you’re struggling with breakouts, barrier damage, or just want to understand your skin better, she takes a calm, realistic approach to help you get there.

Her focus isn’t quick fixes. It’s education, balance, and long term results from gut health to skincare routines that actually make sense. She believes good skin is built slowly, honestly, and together.

Nobubelo built The Sigma Clinic for people who want more than surface-level treatments. It’s for those ready to understand their skin, trust the process, and enjoy getting there.

 Trustindex verifies that the original source of the review is Google. I had teeth whitening with Bubbles. I’m a 41 year old who searched high and low for somewhere that did teeth whitening in the local area. Bubbles was doing a Wowcher offer which I instantly snapped up. My teeth whitened 2/3 shades lighter. Not at any point did I feel uncomfortable in the salon or with Bubbles, to be honest I felt over comfortable. The salon is homely. The bed was lovely a soft and welcoming. Everywhere was clean and stunning and Bubbles is a really lovely lady. I will 100% be returning to get my teeth whitened again in the future plus a facial!

 Trustindex verifies that the original source of the review is Google. I had an amazing microneedling session with bubbles who went through my skin type, consultative approach to skin treatment and care. Easy to book.

Overall service was second to none. It didn't feel like a rushed service, lots of laughing and positive energy during my treatment done. I reccomend her to all people in Essex and Chelmsford as she is truly great at her craft and looks after her clients.

Look forward to coming again soon!

 Trustindex verifies that the original source of the review is Google. I had a Bio Repeel, a back facial and teeth whitening at The Sigma Clinic and I’m honestly so impressed. The whole experience feels calm, refined and really personalised. My back has struggled with breakouts for a long time, and I was told from the start that it would be a journey rather than a quick fix. Even after the first session I noticed my skin felt smoother and looked less inflamed. I like that everything was explained clearly and nothing was rushed.

The back facial was incredibly thorough and my skin looked so much cleaner straight after. The teeth whitening was also brilliant. My teeth lifted several shades without any sensitivity which has never happened before.

I’ve already booked in for my next Bio Repeel because I finally feel like I’m getting the right support with my skin. Would absolutely recommend The Sigma Clinic to anyone who wants expert care and real results.

 Trustindex verifies that the original source of the review is Google. I’ve had two facials with Bubbles so far my first was a classic facial to get my skin prepped, and my second was microneedling with a BioRePeel and I’m honestly so impressed with the whole experience. From the moment I walked in, she really took the time to understand my skin, my lifestyle, and what I actually wanted to achieve. You can tell she genuinely knows her stuff and cares about results, not just selling treatments.

The environment itself is calm, clean, and feels really high-end without being intimidating. After the first facial my skin already felt smoother and more balanced, and after the microneedling with the peel, I noticed a visible glow and tighter texture within a few days. She explained everything so clearly throughout the treatment and checked in with me after, which made it all feel really personal.

You can tell Bubbles is passionate about what she does. it’s refreshing to have someone who genuinely listens, not just performs a routine. I honestly can’t wait to go back and keep working on my skin journey with her. Highly recommend! Xx
