What Is a Lip Flip?

A lip flip uses a small amount of botulinum toxin injected into the upper lip muscle to gently relax it. This allows the lip to roll subtly outward, revealing more of the pink lip tissue and creating the appearance of a fuller upper lip — without adding any volume.

Unlike lip fillers, which physically augment the lip with hyaluronic acid, the lip flip works purely through muscle relaxation. The orbicularis oris muscle — which circles the mouth and causes the lip to curl inward — is gently relaxed at precise points along the upper lip border.

The result is a subtle, natural enhancement that accentuates the Cupid's bow and reveals more of your existing lip shape. It's ideal for patients who want a noticeable but understated improvement, or who wish to try lip enhancement before committing to filler.

Our doctors assess each patient's lip anatomy, muscle strength, and aesthetic goals to determine the optimal placement and dosage — typically 4–6 units of botulinum toxin.

How the Procedure Works

The procedure takes just 10–15 minutes. Using a fine needle, small doses of botulinum toxin are placed at 2–4 strategic injection points along the upper lip border.

During your consultation, your doctor will assess your lip anatomy and discuss your goals. The injection sites are carefully selected to target the orbicularis oris muscle whilst maintaining natural lip mobility and expression.

The treatment is well-tolerated by most patients, with only a mild pinch sensation. Topical anaesthetic can be applied if preferred. You can return to normal activities immediately — there is no downtime.

Results develop gradually over 3–7 days, with the full effect visible by day 10–14. This gradual onset ensures a natural-looking enhancement rather than an abrupt change.

Lip Flip vs Lip Filler

A lip flip relaxes muscle to reveal more lip tissue. Lip filler adds physical volume with hyaluronic acid. They serve different purposes and can be combined for comprehensive enhancement.

Lip Flip (Botox)

• Relaxes muscles — no volume added
• 10-minute procedure
• Results last 2–3 months
• £175
• Subtle, natural enhancement
• Ideal first step for lip enhancement

Lip Filler (HA)

• Adds hyaluronic acid volume
• 30–45 minute procedure
• Results last 6–12 months
• From £300
• Subtle to dramatic options
• Shapes and defines lip contour

Combined approach: Many patients achieve optimal results by combining both — the lip flip for upper lip muscle relaxation alongside filler for volume and definition. Your doctor will advise the best approach during consultation.

Am I Suitable?

May Be Suitable

• Thin upper lip that curls inward when smiling
• Desire for subtle, natural enhancement
• First-time lip enhancement patients
• Smoker's lines around the mouth
• Wanting to "test" lip enhancement before filler

May Not Be Suitable

• Expecting dramatic volume increase
• Active cold sores or lip infections
• Pregnancy or breastfeeding
• Allergy to botulinum toxin
• Neuromuscular disorders

What to Expect

Results appear gradually over 3–7 days, with full effect by day 10–14. The enhancement lasts 2–3 months before a maintenance appointment is needed.

Because the lips are a high-movement area, Botox tends to metabolise faster here than in other facial areas such as the forehead. Most patients schedule maintenance every 2–3 months for consistent results.

Side effects are generally minimal and temporary. You may experience mild swelling, slight numbness (resolving within hours), or brief difficulty with precise lip movements such as drinking through a straw. Asymmetry is rare and easily corrected.

Your doctor will discuss realistic expectations during consultation, ensuring the treatment aligns with your aesthetic goals.

Aftercare & Recovery

No downtime required. You can return to normal activities immediately after treatment. A few simple precautions help ensure optimal results.

Avoid straws and excessive lip pursing for 24 hours
Do not lie flat for 4 hours post-treatment
Avoid makeup on the injection area for 24 hours
Apply ice if mild swelling occurs

Lip Flip Botox London — Expert Upper Lip Enhancement at Harley Street

Cosmedocs offers doctor-led lip flip botox treatments for natural upper lip enhancement at our Harley Street clinic in London. The lip flip procedure uses precise botulinum toxin injections into the orbicularis oris muscle to relax the upper lip, revealing more pink lip tissue for a subtly fuller appearance without adding volume. Our GMC-registered doctors have been performing lip enhancement treatments since 2007.

What Is a Lip Flip and How Does It Work?

A lip flip uses botox injections in the upper lip to relax the orbicularis oris muscle. This muscle relaxation technique allows more of the pink lip tissue to show, creating the illusion of fuller lips without adding volume through dermal fillers. The botox lip flip procedure targets specific injection points along the top lip border. Lip flip results begin appearing within 3-7 days, with full effects visible by day 10-14. Results typically last 2-3 months.

Lip Flip vs Lip Filler Comparison

A lip flip uses botox on lips to relax muscles and reveal more of your existing lip, whilst lip fillers add hyaluronic acid volume. Lip flip and filler combinations can provide comprehensive results. The lip flip cost is £175 at Cosmedocs. Many patients achieve optimal results by combining both treatments for complete lip enhancement. Our aesthetics is invisible art — bold, natural, always your way.

Lip Flip Aftercare and Recovery

Lip flip aftercare involves avoiding straws, excessive lip movement, and lying down for 4 hours post-treatment. Apply ice if needed for mild swelling. The lip flip procedure recovery is minimal with immediate return to activities. Avoid makeup on the treatment area for 24 hours and follow all aftercare instructions provided.

Lip Flip Injection Points and Sites

Lip flip injection points are strategically placed along the upper lip border, targeting the orbicularis oris muscle. The lip flip injection sites typically include 2-4 points across the top lip, where to inject botox for lip flip depends on your specific lip anatomy. Our expert doctors precisely determine the optimal injection sites for natural results. The typical dosage is 4-6 units of botulinum toxin.

Can Lip Flip Help with Smoker's Lines?

Yes, lip flip for smokers lines can reduce perioral wrinkles by relaxing the muscles causing lip curl and vertical lip lines. Botox for lip lines works together with the flip technique to smooth vertical lines whilst enhancing the upper lip appearance. This is particularly effective when combined with other perioral rejuvenation treatments.
