I had jaw filler to disguise sagging jowls. Dr Nick Sinden was the practitioner who led the training on the day I had my treatment - I am delighted with the result and I couldn’t have been in safer hands.

I had a wonderful training experience with Natalja. I came in with low confidence and she addressed my concerns and helped me gain full confidence in my skills and abilities with her lip injection technique and consultation method. I have left feeling excited to see clients for lip enhancement.
I had a brilliant experience on today’s lip injection course, and I just wanted to say how grateful I am to have been taught by Natalja. She was warm, knowledgeable, and incredibly supportive throughout the whole session. Her teaching style is very clear and practical — she really took the time to explain the anatomy, techniques, and safety aspects in a way that made sense and felt manageable, even when things got a bit technical. I especially appreciated how hands-on the session was. Natalja was there every step of the way, giving thoughtful feedback and guidance while also allowing us space to grow and build confidence. The live model experience was especially valuable, and I genuinely walked away feeling more capable and reassured in my own abilities. You can tell she really cares about her students doing well and keeping patients safe. Would definitely recommend this course to anyone looking to improve their lip technique — and Natalja’s such a gem of a trainer!

Natalja was an excellent teacher. Really knowledgable and patient with me. Thoroughly enjoyed the day and would recommend
The course was well structured and there was a good amount of both theory and practical experience. Natalja is very experienced and liked by patients. She has great knowledge and was very happy to ask all my questions. The level of teaching was appropriate, I learnt lots and had a really fun day.
I did my second course with Natalja at cosmetic courses today, it was well organised as before and Natalja is a fantastic and experienced trainer, she is so encouraging and supportive. Highly recommended.
Natalija taught me the Advanced Toxins and Fillers course and I had a great experience and was very grateful for her teaching. She is very patient and shares her valuable experience and skills with us. After her class, I felt more confident in my injection skills. Thank her very much.
I have had the pleasure of taking Natalja’s cosmetic course twice, and I can confidently say that she is an outstanding tutor. Her deep knowledge, patience, and passion for teaching make learning both enjoyable and highly informative. Nataliya goes above and beyond to ensure that every student understands the material thoroughly, providing clear explanations and hands-on guidance. She creates a supportive and encouraging environment, which makes it easy to ask questions and gain confidence in practical skills. Her expertise in the field is truly impressive, and her ability to break down complex techniques into easy-to-follow steps has been invaluable. Thanks to her, I feel much more skilled and prepared in my cosmetic practice. I highly recommend Nataliya’s courses to anyone looking to expand their knowledge and perfect their techniques in the cosmetic industry. She is a fantastic mentor, and I am grateful for the opportunity to have learned from her!
Natalja our trainer was one of the best I’ve had, very informative, very reassuring. I came out feeling much more confident and competent with providing dermal fillers!
Natajia was absolutely great! She took the time to explain us step by step how to do inject different areas on face. She is very professional and o highly recommended if you are new in cosmetics or even if you have experience as there is always something else to learn from her!
Fabulous experience as a model. Professional service from start to finish
Having Natalja as my trainer today was great, she really increased my confidence as an aesthetic injector She had a calm and reassuring manner
I feel so confident now to perform treatments after completing the course with Natalija Aleksejeva. The sessions were incredibly informative, and she covered many of the questions we had in great detail. I highly recommend this course to anyone looking to enhance their skills!
Amazing place, as a model I always leave happy
Thank you to Charlotte at your London branch. Charlotte listened to what I wanted and helped me to restore my faith in cosmetic treatments again, after having a long break because I was not receiving the end result that I was after. Charlotte consulted with me at the appointment, did not rush me, did not try to push treatment on me and I came away feeling I can trust this company in helping me with the results I am after. Thank you Charlotte for taking the time to listen and for my first treatment with you.
Natalia was an amazing trainer!! Friendly, warm, welcoming and extremely knowledgeable!! I felt very at ease with her teaching and she has definitely given me more confidence to elevate to the next level of my own clinical practice!
I attended Cosmetics Courses for a Facial Contouring session and found it incredibly useful. I was lucky enough to have Natalja, who was very informative and supportive throughout. She shared multiple tips for dermal filler treatments and there was lots of great practical experience. Thank you Natalja- I feel much more confident with my techniques.
