Lip filler styles: what Russian lips vs natural actually look like

TL;DR

• The two lip filler styles patients ask for most are the Russian (vertical) technique and the natural or classic (horizontal) technique.
• Russian lips use vertical injection points to lift the lip and sharpen the cupid’s bow. The trade-off is a higher reported risk of filler moving out of place.
• Natural lip filler places product along the vermilion border and body of the lip for hydration and gentle volume, keeping your existing lip shape.
• A lip flip is not filler at all. It uses a few units of botulinum toxin to roll the upper lip outward, with no added volume.
• Style should be chosen from your lip anatomy and what the tissue can hold, not from a photo on a phone. At CoLaz, dermal fillers start from £150 per 1ml and every plan starts with a free consultation.

Most people who book a lip appointment do not actually ask for a product. They ask for a look. They show us a photo, or they say “Russian lips”, or they say “just natural, nothing obvious”. Those are lip filler styles, not products, and the difference between them is where the needle goes and which direction the lip is pushed.

This is a plain guide to the two styles patients ask for most, plus the lip flip, which is not filler at all. We will also cover the honest limits: what your own lip anatomy will and will not hold, and the warning signs that lips have been overfilled.

What are the main lip filler styles?

The main lip filler styles are defined by injection direction and depth, not by the filler itself. A recent narrative review in the Journal of Cutaneous and Aesthetic Surgery describes at least ten named lip techniques, including linear retrograde, serial puncture, cannula, cross-hatching, the Russian or tenting technique, the French kiss technique, the Paris lip and the six-step approach.

In UK clinics, patients usually mean one of three things:

• Russian, or tenting. Vertical injection points that lift the lip upward and increase visible lip height.
• Natural, or classic. Horizontal placement along the border and body of the lip for hydration, softness and gentle volume.
• Lip flip. No filler at all, a small dose of botulinum toxin that rolls the upper lip outward.

Everything else is a variation on how those points are placed. The same hyaluronic acid gel can produce a very different lip depending on which route the injector takes.

What is the Russian lip technique?

The Russian lip technique uses a series of small vertical injections from the inner body of the lip out toward the border, so the lip is lifted and flattened forward rather than pushed outward. The review above describes it as producing “increased vermilion height”, which is the visible red part of the lip, with a sharper cupid’s bow and a more heart-shaped upper lip.

That is the appeal. The honest trade-off is that the same review flags a “higher risk of migration and unnatural results” for vertical techniques, and notes that filler migration is most common in the upper lip because of constant movement of the orbicularis oris, the ring of muscle around the mouth.

Migration is what patients are describing when they say someone has a shelf or a shadow above the lip line. The gel has moved out of the lip and into the skin above it. It is treatable, but it is easier to avoid than to correct.

Russian lips also need the right starting anatomy. A lip that already has good vermilion height and a defined border can take a vertical lift well. A very thin lip with a short distance between the nose and the lip line often cannot, because there is nothing to lift into.

What does natural or classic lip filler look like?

Natural lip filler follows the shape you already have, adding hydration and gentle volume without changing the proportions of the mouth. Product is placed along the vermilion border for definition and into the body of the lip for softness, usually in horizontal passes rather than vertical ones.

Depth is the part patients rarely hear about. Older work on injection depth notes that placing product too superficially causes visible beading, while genuinely thin lips do better with a deeper structural layer first and a superficial layer afterwards. That is a two-appointment plan, not a single 1ml session.

A 2025 study of the multi vector approach, which maps the lip into geometric zones and treats several planes, reported a mean volume of just 1.06ml per patient across 253 women, with oedema in 15.8% and bruising in 11.1%, and no cases of vascular occlusion over nine to twelve months. That average is worth holding onto. A well-planned natural result is usually about placement, not about millilitres.

Lip filler styles compared: Russian vs natural at a glance

	Russian / vertical	Natural / classic
Injection direction	Vertical, inner lip out to border	Horizontal, along border and body
Main effect	Lifts lip height, defines cupid’s bow	Hydrates, softens, gentle volume
Best starting anatomy	Existing vermilion height and clear border	Most lip shapes, including thin lips
Look	Defined, flatter front profile, heart-shaped upper lip	Fuller version of your own lip
Reported trade-off	Higher migration risk in the upper lip	Less dramatic shape change per session
Typical build	Often staged over more than one session	Often staged over more than one session

Neither column is the better technique. They answer different questions. The mistake we see is patients choosing the column rather than the outcome.

Which lip filler style suits your face?

The style that suits you is the one your lip tissue can actually hold, which is decided by looking at your mouth, not by looking at a photograph. We assess lip height, the length and shape of the philtrum, how much of your teeth show when you smile and talk, the strength of the border, and how symmetrical the two halves of the lip are at rest.

A few patterns come up repeatedly:

• Short upper lip, teeth already visible at rest. Vertical lifting can make the upper lip look longer and heavier. A gentler natural approach usually reads better.
• Good height, soft or blurred border. Border definition, in either style, gives the biggest visible change for the smallest volume.
• Thin lower lip carrying the balance. Treating the upper lip alone can unbalance the mouth. We often plan a small correction to the lower lip in the same session.
• Noticeable asymmetry. This gets mapped and photographed before anything is injected, because a symmetry correction and a volume increase are two different plans.

This is where I say no more often than patients expect. We have turned patients away for fillers because of active acne, an active cold sore or certain medications, and we would rather have that conversation at the free consultation than on the treatment bed.

What about a lip flip instead of filler?

A lip flip is not filler. It is a very small dose of botulinum toxin placed into the superficial fibres of the muscle around the upper lip, which relaxes the inward pull and lets the lip roll slightly outward. A systematic review of the technique describes doses in the region of 4 to 6 units producing a modest increase in visible upper lip height with no change in lip volume.

The effects are honest ones. You get a slightly fuller-looking upper lip when you smile and talk. You do not get more lip. Transient side effects reported in the literature include difficulty whistling or drinking through a straw for a few weeks.

A lip flip suits someone whose upper lip disappears when they smile and who does not want volume. It typically lasts around the same three to four months as other anti-wrinkle injections, so it is a shorter commitment than filler. Some patients use it alongside a small amount of filler rather than instead of it.

Why do some lips end up looking overfilled?

Overfilled lips are almost always the result of repeat treatment before the previous filler has gone, rather than one heavy session. Hyaluronic acid fillers in the lip typically last 6 to 18 months depending on the product and the area. If someone tops up every three months because the initial swelling has settled and they miss it, volume stacks.

The signs patients describe as the “duck lip” look are usually a combination of three things: too much product for the tissue, product sitting too far forward of the teeth, and filler that has migrated above the lip line. That third one is the technique-dependent part, and it is the reason the vertical style needs careful hands.

There is a wider pattern behind this. Save Face, one of the two UK registers, reported 2,824 complaints about unregistered practitioners in a single year, up from 2,436 the year before, with dermal fillers accounting for 69% of them.

How do we plan lip filler at CoLaz?

We plan lips over a free consultation first, then a treatment appointment, and we do not sell a fixed multi-session package on day one. At the consultation we assess your lip anatomy, talk through which style your tissue will actually hold, and write the plan down before anything is booked.

The practical detail for dermal fillers at CoLaz:

• Price: from £150 per 1ml for lip, jawline, chin, naso-labial or marionette treatment.
• Appointment length: 30 to 60 minutes, including time for topical numbing cream.
• Immediate aftermath: swelling or bruising is common for 24 to 72 hours.
• Settled result: assess at 2 weeks, not on day one.
• How long it lasts: typically 6 to 18 months, depending on product and area.

One of the most common conversations we have is the one where the patient has come in asking for a specific product because a friend or a video recommended it. A patient at our Reading clinic once asked for cheek filler because a colleague had had it. What she was actually unhappy with was jawline laxity and a tired look, and filler in the cheeks would not have given her that. We planned something different, and it worked. Lips are the same principle. The right technique is whichever one matches the goal, not whichever one you walked in naming.

Who should not have lip filler?

Some people are not candidates, and a good clinic will tell you before you book. We do not treat lips if you are pregnant or breastfeeding, if you have an active cold sore anywhere around the mouth, if you have certain autoimmune conditions, or if you are on medication that makes bleeding or infection risk unacceptable.

Age is a legal line, not a judgement call. Under the 2021 Act, it has been illegal in England since 1 October 2021 to give botulinum toxin or cosmetic fillers to anyone under 18 for cosmetic reasons, and parental consent does not change that.

If you have had filler elsewhere and are unhappy with it, bring that to the consultation rather than booking a new treatment on top. Dissolving and re-planning is often the better route, and it needs assessing in person.

Checking the clinic before you book a lip appointment

Lip filler is the most-complained-about non-surgical treatment in the UK, so the clinic matters as much as the technique. NHS advice is to check the person treating you is on a register accredited by the Professional Standards Authority, such as the JCCP or Save Face, and to avoid practitioners who have only completed a short training course.

Two more things worth knowing:

1. Complications are real and time-critical. Filler injected into or against a blood vessel can block it. The vascular occlusion guideline published in the Journal of Clinical and Aesthetic Dermatology stresses that ischaemic changes can appear instantly or within a few hours, and that treatment with hyaluronidase needs to start straight away. Ask your clinic directly whether they stock hyaluronidase and what their emergency protocol is. Anatomy is the reason this matters: measurements reported alongside the superior labial artery put it around 3.3mm to 3.9mm deep at the vermilion border, which is why injection depth is not a stylistic preference.
2. Regulation is still catching up. The House of Commons Library briefing on the licensing scheme sets out the government’s plan for a risk-tiered licensing model in England, which is not yet fully in force. Until it is, the voluntary registers are the practical safeguard.

Advertising is regulated even where the treatment is not. UK advertising rules prohibit ads for cosmetic interventions being directed at under-18s, ban public advertising of prescription-only medicines by brand name, and say marketers must not trivialise the procedure. A clinic running competitions or discount countdowns for lip filler is telling you something about how it treats risk. Our guide to choosing a clinic goes into the full checklist.

Your next step

If you are trying to decide between a lifted, defined lip and a softer natural one, the useful next move is to have someone look at your mouth and tell you honestly which one your anatomy suits. That is what the assessment is for, and it costs nothing.

Book a free consultation at any of our seven UK clinics. We will map your lips, talk through both styles, write down a plan with the volume and the spacing, and give it to you before you commit to anything.
