Six months have passed, the reminder pings on your phone and your lips still look lovely in every photo. Does that mean you should book anyway? Not necessarily. The best time for lip filler maintenance is guided by the result you have and the change you would like, rather than a date in the diary. RPA describes a typical duration of six to twelve months for its London lip treatment, with individual variation.
A duration estimate is your planning guide
The product used, the treated area and your individual response all affect how long a visible change lasts. A range is wonderful for planning, and a review shows when your lips might benefit from more filler.
The American Academy of Dermatology advises discussing longevity for the specific filler and area, which tells you far more than comparing a friend’s timetable with your own.
Ask what the estimate refers to: a noticeable aesthetic effect, a suggested review interval or the point at which maintenance might be considered. A clinic reminder is a friendly prompt to review rather than a recommendation to inject again.
Start from the settled result
The fullness straight after an appointment includes swelling, so as it resolves your lips may look smaller than they did in the treatment room while your result is still very much there.
Choose a sensible baseline with your practitioner once the early reaction has settled. A clear photograph in ordinary light is ideal, taken in a consistent position with a relaxed expression.
That makes later comparisons genuinely meaningful, rather than measuring today’s lips against a swollen first-day picture.
What has changed since your appointment?
Try describing the difference rather than starting with a volume. Perhaps the border looks softer, the fullness is less noticeable or an original imbalance has become more apparent. Or perhaps nothing has changed that you would like to alter.
That last answer is a happy one. Maintenance is entirely optional, and you are free to let your result evolve rather than preserving the fullest version of it.
If you are unsure, compare with pictures from before treatment as well as after, because familiarity can make subtle changes harder to see. The aim is simply to understand how your lips look now.
A review has many possible outcomes
Your practitioner may suggest leaving the result alone, waiting longer or looking at a particular concern before discussing further treatment, and a good review welcomes all of those possibilities.
Share any previous products, dates and clinics, even if the treatments were some time ago. If you have changed provider, bring whatever records you have rather than relying on a remembered syringe colour or an approximate product name.
The AAD’s preparation guidance emphasises discussing previous cosmetic treatments and your health history. Those details help shape your plan, and you should always feel comfortable seeking another opinion.
A top-up gets the same care as a first visit
The word “top-up” can make a repeat appointment sound smaller than it is. Even a small amount is a procedure in its own right, planned with the same care.
Your practitioner talks you through the proposed product and why further treatment would help. Your clinician runs through your medical history at the consultation.
Budget for a plan you choose to continue
A single-session price only tells part of the story, so ask about review arrangements, future treatment costs and what aftercare includes. The NHS recommends considering the full costs of cosmetic procedures, including potential future care.
You can decide that your result is worth maintaining, that you would prefer a longer gap or that you are happy to stop, and that flexibility belongs in the conversation from the very start.
At RPA’s medically led London clinic in the Harley Street medical district, the most useful question is “What would another treatment add to the result I have now?” rather than “How many months has it been?” Contact the Wimpole Street team to arrange a review or discuss a first appointment, and bring the result you love along with any change you are considering.
Your questions, answered
Lucky you. A duration estimate is a guide rather than a deadline, so an otherwise lovely result does not need intervention just because time has passed. Bring any questions along to your review.
No fixed amount suits every review. Your current result and the goal you agree together guide the assessment.
There is no verified basis for promising longer-lasting filler through extra water, although staying hydrated is lovely for general wellbeing. Ask about expectations for your specific product.
Original Profhilo has a different, skin-quality purpose, so it is a separate treatment rather than a way to maintain lip shape or fullness.
Yes, whenever you like. Repeat cosmetic treatment is entirely optional, and you can talk through how your appearance may change rather than booking out of habit.
