0.5ml or 1ml of Lip Filler? How Much You Actually Need
For most people having lip filler for the first time, 0.5ml is enough to make a clear but natural difference, and it is often the right place to start. 1ml tends to suit lips that are naturally very thin, lips that have lost volume and shape with age, or someone building on an earlier treatment who wants more. The right amount depends on your lips rather than the price list, and it is decided at the assessment, before anything is injected.
Here is what each amount looks like in practice, who each tends to suit, and why, with lips, less is so often more.
How much is 0.5ml, really?
Less than most people imagine. A teaspoon holds 5ml, so 1ml of filler is about a fifth of a teaspoon and 0.5ml about a tenth. Shared across both lips, that is a small amount of product, and in the lips a small amount makes a visible difference. It is also why the conversation is as much about where the filler goes as how much of it there is.
What 0.5ml tends to suit
A first treatment, when you want to see how your lips respond before deciding on more
Better definition along the border, or a crisper cupid's bow
Correcting a mild asymmetry
A subtle lift in volume, the kind people notice as "you look well" rather than "you've had your lips done"
Refreshing an earlier result that has started to soften
What 1ml tends to suit
Lips that are naturally very thin, where half a millilitre would barely register
Lips that have lost volume and shape with age
More noticeable volume, built in proportion to the rest of the face
Treating volume and definition together, across both lips
1ml doesn't mean a dramatic result. Placed well and in proportion, a full millilitre can look entirely natural; placed badly, half that can change the shape of a mouth for the worse. Placement decides how a result reads far more than volume does.
Why less is often more with lips
There are three reasons we often suggest starting smaller.
Adding is simpler than taking away. Hyaluronic acid filler can be dissolved if it ever needs to be, but adding a little more at a later appointment is a far easier conversation than removing some.
Swelling exaggerates the first few days. Your lips will look fuller in the first 48 hours than they will once everything has settled, so the day-three result is not the one to judge. Most of the swelling has gone by day five to seven, and we review at two weeks.
Too much, too often, is a common reason lips stop looking natural. Repeated top-ups before the previous filler has worn away can gradually change the shape of the lip, and are one of the factors linked to filler moving beyond the border of the lip.
How we decide how much you need
Lip filler is priced by volume, but the volume shouldn't be chosen from the price list. At the assessment, Dr Ashraf looks at your lips at rest and when you talk and smile, at the balance between the upper and lower lip, at the border, and at how the lips sit within the lower face as a whole. The amount and the price are agreed with you before anything is injected.
Sometimes the answer is less than you expected. Occasionally it is a different treatment altogether, because lips treated in isolation, without reference to the chin and the area around the mouth, are a common reason filler looks done rather than natural. If that is the case, we will tell you.
What each costs at our Reigate clinic
Lip filler, 0.5ml: £300
Lip filler, 1ml: £350
Filler dissolving: £250
The difference between the two is small, which is exactly why it shouldn't be what decides it. If 0.5ml is right for your lips, that is what we will recommend. Your two-week review is included, and every price at the clinic is on our pricing page.
How long it lasts
Typically nine to twelve months, whichever amount you have, depending on the product used, the volume placed and your own metabolism. There is no need to top up before it has worn away. Our guide to how long dermal fillers actually last goes into more detail.
Who treats you
Every treatment at Mindful Aesthetics is carried out by Dr Haroon Ashraf, a GMC-registered doctor who injects full time, using hyaluronic acid filler only, which can be dissolved if it ever needs to be. He has trained over 1,000 doctors, dentists and nurses in injectable technique and complication management. You leave with written aftercare and his direct contact details. We do not treat anyone under 18.
Our lip filler page has before and after photographs of our own patients and a short video of Dr Ashraf explaining the appointment. When you are ready, book a consultation.
Questions we're asked
Is 0.5ml enough to notice?
In most lips, yes. It is a subtle change: more definition and a little more volume, rather than an obviously different mouth. For very thin lips it can be too little to register, and if we think that is the case, we will say so at the assessment.
Can I start with 0.5ml and add more later?
Yes. We would wait until the first treatment has fully settled, which is why the two-week review is the natural point to decide whether you want more.
Will 1ml make my lips look too big?
Not if it is placed in proportion. A millilitre is about a fifth of a teaspoon, and in lips that need it, it can look entirely natural. When lips look overdone, the cause is usually placement or repeated top-ups rather than a single millilitre.
I'm having lip filler before a wedding or an event. How far ahead should I book?
Give it at least a week for the swelling to settle, and two to three weeks if you want room for the review as well. Our guide to treatments before your wedding has the full timeline.
