Lip Flip: More Visible Upper Lip Without Filler

The Lip Flip is a non-invasive aesthetic treatment that uses neuromodulators to subtly relax the orbicularis oris muscle, allowing the upper lip to gently roll upwards.

What is a Lip Flip and how does it work?

The Lip Flip is a non-surgical technique designed to enhance the appearance of the upper lip. It involves the precise application of a small amount of neuromodulators at specific points in the orbicularis oris muscle, which surrounds the mouth. This action relaxes the superficial muscle fibers, allowing the border of the upper lip to gently evert upwards.

The result is greater exposure of the pink part of the lip, creating an optical illusion of more volume and a fuller smile. This treatment is particularly suitable for people who feel their upper lip “disappears” when smiling, or who desire an enhancing effect without adding artificial volume.

Lip Flip vs. Hyaluronic Acid Lip Filler?

Although both treatments aim to improve lip aesthetics, their mechanisms and results are distinct. The Lip Flip modifies the position of the upper lip through muscle relaxation, while hyaluronic acid filler adds direct volume. The choice between the two depends on each patient's individual goals.

The Lip Flip offers a subtle and natural improvement, ideal for those who desire a discreet change. Hyaluronic acid, on the other hand, allows for a more noticeable volume increase and can correct asymmetries or define the contour. Our doctors will assess which treatment is most suitable for you in a personalized consultation.

Who is a good candidate for a Lip Flip?

The Lip Flip is an excellent option for individuals seeking a subtle improvement in the appearance of their lips. It is especially beneficial for those with an upper lip that tends to “disappear” or thin out when smiling. It is also an alternative for those who wish to avoid volume augmentation with fillers.

Ideal candidates have realistic expectations about the treatment results. In the initial consultation, our doctors will evaluate your facial anatomy and aesthetic goals. This ensures that the Lip Flip is the most suitable option to achieve the desired harmony.

The procedure: what to expect?

The Lip Flip procedure is quick and performed in the clinic. Once the upper lip has been assessed, the doctor will administer small injections of neuromodulators at strategic points. The process is generally well-tolerated, and a slight momentary discomfort may be felt.

No anesthesia is required, although a topical cream can be applied if the patient prefers. The total treatment duration is about 10 to 15 minutes. After the procedure, patients can resume their daily activities immediately.

Results and recovery

The effects of the Lip Flip are not immediate and develop gradually. Generally, results begin to be visible within 3-5 days, reaching their full effect around 10-14 days. The upper lip will appear slightly everted, creating a fuller and more defined look.

Recovery is minimal; some patients may experience mild redness or slight swelling at the injection sites, which quickly subsides. It is important to follow the doctor's post-treatment instructions to optimize results. The duration of effects typically ranges from 2 to 4 months, after which a maintenance session can be considered.

"The key to a successful Lip Flip lies in precise dosing and strategic placement of injections. A conservative approach tailored to individual anatomy is fundamental to achieve natural eversion and avoid any alteration in lip function." – Dr. Sol Monsalve, Medical Director of Santé Clínica Estética.

Frequently Asked Questions

Does the Lip Flip affect my speech or smile?

When the treatment is performed by an experienced doctor with appropriate dosing, the Lip Flip should not significantly affect your speech or smile. The goal is subtle muscle relaxation, not complete paralysis. You may feel a slight difference initially, which usually subsides as you get used to the effect.

Can the Lip Flip be combined with hyaluronic acid fillers?

Yes, in some cases, the Lip Flip can be complemented with hyaluronic acid fillers for a more comprehensive effect. For example, the Lip Flip can be used to evert the upper lip, and a small volume of hyaluronic acid can define the Cupid's bow or hydrate the lips. This combination is individually assessed during the medical consultation to ensure facial harmony.

How long does it take to see Lip Flip results?

The results of the Lip Flip are not immediate. Effects begin to be noticeable between 3 and 5 days after treatment, and the final result is fully appreciated around 10 to 14 days. It is important to be patient and allow the neuromodulator to act completely.

Are there any contraindications for the Lip Flip?

As with any medical treatment, there are some contraindications for the Lip Flip. These include pregnancy or breastfeeding, certain neuromuscular diseases, active infections in the treatment area, or a known allergy to the components of the neuromodulator. A prior medical evaluation is essential to rule out any risks and ensure the suitability of the treatment.
