I went to Dr Harry Clinic after both a recommendation and doing a lot of research, as this was my first anti-wrinkle injection treatment and choosing someone I truly trusted was really important to me. From the moment I arrived, Dr. Harry immediately made me feel at ease. He was so lovely, professional, and took the time to explain everything in detail. Most importantly, he really listened to what I wanted - especially my preference for a very natural look. Two weeks later, I had my complimentary follow-up appointment and I was already so happy with the results. At the follow-up, Harry was an absolute perfectionist, carefully assessing everything to ensure it was as balanced and natural as possible, with a small top-up where needed. Overall, my experience exceeded all expectations. If it’s your first time having treatment, or you’re looking for a new injector, I genuinely cannot recommend Dr Harry Clinic enough. One of the best decisions I’ve made.

Dr Harry is absolutely amazing, I can’t recommend him enough. I had my usual skin maintenance treatments yesterday, and for the first time I decided to try a lip booster. Harry was so informative, knowledgeable, and reassuring throughout, and he made me feel completely at ease. I was originally offered standard lip filler, but as I’m in my 60s I wanted something more subtle and natural-looking, the lip booster felt like the perfect choice. I left the clinic with only a little swelling (nothing too bad at all) and my lips already look healthier, more youthful, and beautifully natural. I’m genuinely thrilled with the result and can’t thank him enough. Five-star-plus treatment every time. His prices are very reasonable, and his manner with patients is kind, professional, and wonderful. I’m already looking forward to my next appointment, even if I have to wait a few months because the results last so well. Thank you Dr. Harry ❤️

Dr. Harry is incredibly knowledgeable and really takes his time to talk you through everything, answer any questions, and ensure you’re comfortable throughout the whole appointment. I never felt rushed, and he explained the treatment and expected results clearly, which made me feel really confident in the process. I’m so pleased with my results and wouldn’t hesitate to recommend him.

I visited Dr Harry after having my lips done by a few, other practitioners and my experience was positively incomparable. Harry was extremely thorough with his questioning, support and actual practice, I felt reassured and at ease, alike did my Mum, at the hands of Harry. I had 0.6ml of lip filler and was extremely impressed that he reevaluated my lips afterwards, adding in the remaining filler into specific areas. I did not have 1 single bruise, despite coming up black and blue in the past, and my lips are the most symmetrical they have ever looked. 1 million percent the best investment I have made to my face and I would never recommend going to anybody else! I visited the Chiswick clinic and it was beautiful🫶🏼 thank you Harry

Forehead lines, also known as horizontal forehead wrinkles or worry lines, are among the most common signs of facial ageing and one of the primary reasons patients seek anti-wrinkle injection treatments.
These horizontal lines develop across the forehead as a result of repeated muscle contractions when raising the eyebrows, expressing surprise, or concentrating.
The formation of forehead lines is a natural part of the ageing process, beginning with dynamic wrinkles that appear only during facial expressions and gradually becoming static lines that remain visible even when the face is at rest.
Understanding this progression is crucial for determining the most appropriate treatment approach and achieving optimal results.
Dr Harry’s expertise in forehead line treatment comes from his comprehensive understanding of forehead anatomy and muscle dynamics, knowledge that has been refined through his role as a trainer in aesthetic medicine.
This expertise ensures that treatments not only smooth existing lines but also prevent the formation of new ones whilst maintaining natural facial expressions.



The frontalis is the main muscle responsible for forehead movement. When it contracts, it lifts the brows and creates horizontal lines across the skin. This muscle works in close relationship with others such as the corrugator and procerus, which contribute to frown lines and brow positioning.
Effective treatment depends on more than just knowing where to inject. It requires insight into how these muscles interact to produce natural expressions. Treatments at the clinic are based on this precise anatomical mapping, which allows for subtle correction and facial balance without compromising movement.
Each forehead treatment begins with a thorough consultation to assess facial structure, muscle tone, brow height, and line severity. From there, a bespoke plan is developed to match the unique movement pattern of your forehead.
Micro-dosing and graduated injection techniques are used to soften lines without causing heaviness or immobility. Small amounts of product are placed strategically across the forehead to ensure even results that respect the way your face moves.
This approach reduces the chance of unwanted effects, such as brow drop or stiffness, and ensures results that look refreshed, never overdone.
Forehead treatments often achieve best results when part of a broader upper-face approach. Treating related areas, such as the frown lines (glabella) and crow’s feet, creates a more balanced, youthful appearance.
A subtle brow lift can also be achieved by adjusting the injection pattern. This not only smooths the forehead but helps open up the eyes and lift the overall expression. Such enhancements require both technical accuracy and an artistic eye, ensuring results that are refined and in proportion with your natural features.
Patient safety is always the priority. A detailed medical consultation is carried out to confirm suitability before treatment. Anti-wrinkle injections are not recommended during pregnancy, breastfeeding, or for individuals with certain neurological or muscular conditions.
Only premium products such as Bocouture by Merz are used, and all treatments are carried out with clinical precision. Thorough aftercare instructions are provided, and every step is taken to minimise risk and ensure you feel confident and well-informed.

Common questions
When performed by an experienced practitioner like Dr Harry, forehead line treatment should not create a frozen appearance. Dr Harry’s technique emphasises natural results that maintain facial expressiveness whilst smoothing unwanted lines.
The number of injections varies based on individual anatomy and the extent of lines present. Typically, 5-8 injection points are used across the forehead, with Dr Harry determining the optimal number and placement for each patient.
Forehead line treatment can sometimes provide a subtle lifting effect that helps with heavy brows, though this depends on individual anatomy. Dr Harry will assess whether this approach is suitable during your consultation.
Most patients can return to normal activities immediately after treatment, though some restrictions apply for the first 24 hours. Dr Harry provides comprehensive aftercare instructions to ensure optimal results.
