Cosmo Clinic Team

The Lip Flip is a non-surgical cosmetic treatment that uses tiny injections of botulinum toxin (Botox) into the upper lip muscle (orbicularis oris). This gentle relaxation causes the upper lip to subtly "flip" outward, creating the appearance of fuller, more defined lips – without adding volume through dermal fillers.

At Cosmo Clinic in Lisbon, the lip flip is performed with a small number of precisely placed injections along the upper lip. Our doctors assess lip anatomy and proportion before recommending it as a standalone or complementary treatment. Results typically last two to three months.

What is a lip flip

The lip flip is an aesthetic medicine treatment in Lisbon that uses small injections of botulinum toxin into the orbicularis oris muscle. By gently relaxing this muscle, the upper lip "flips" slightly outward, appearing more projected and visually fuller, without any added volume from hyaluronic acid filler. For those seeking a softer, more defined smile, it delivers naturally understated results with minimal downtime and a lower commitment than a traditional lip augmentation.

Who is it for

A strong choice for anyone who wants a visually fuller upper lip without resorting to fillers, or who wishes to add subtle definition on top of an existing filler result. Not recommended during pregnancy, breastfeeding, in neuromuscular disorders, or with active infection in the lip area. A medical assessment is required before treatment.

What to expect from the session

During the consultation, our medical team evaluates upper lip dynamics, symmetry, and the desired aesthetic outcome. Four small points of toxin are placed along the upper border of the lip with a microneedle. The session takes around 10 minutes, requires no anaesthesia, and leaves no visible signs of treatment, you are free to carry on with your day immediately.

Results timeline

The lip flip effect begins to show between day 3 and day 5. Full results stabilise between days 7 and 10, with the upper lip more projected when smiling. Average duration is 2 to 3 months, shorter than most Botox applications due to the constant muscular activity of the mouth. A follow-up review is scheduled around two weeks after treatment.

Aftercare

For the first 4 hours after treatment, avoid lying down or drinking through a straw. During the first 24 hours, skip intense physical exercise, saunas, and very hot baths. In the first week, avoid massaging the treated area, postpone aggressive lip treatments, and apply sunscreen whenever you are exposed to the sun.
