What is crow's feet Botox

Crow's feet Botox is one of the most refined applications in aesthetic medicine in Lisbon. Small, precise injections of botulinum toxin are placed into the orbicularis oculi muscle, the circular structure around the eye responsible for the fine lines that fan outwards when you smile. The treatment softens this delicate network of lines and restores a rested, refreshed quality to the eye area without freezing or flattening expression.

Who is it for

Men and women with visible lines at the outer corners of the eyes, whether dynamic (appearing on smiling) or mildly static (visible at rest), are ideal candidates. Many also seek treatment as a preventative measure, particularly those who spend long hours in sun or in front of screens. Contraindicated during pregnancy, breastfeeding, in neuromuscular conditions, and with active infection in the eye area.

What to expect from the session

The consultation begins with a careful assessment of ocular dynamics and the condition of the periorbital skin. Botulinum toxin is then applied with an ultra-fine microneedle at 3 points on each side. The session is quick, 15 to 20 minutes, no anaesthesia is needed, and you can step straight back into your day immediately afterwards.

Results timeline

A perceptible softening around the eyes begins between day 3 and day 5. Full effect stabilises between days 10 and 14, with the crow's feet lines noticeably reduced. Average duration is 3 to 6 months, with a follow-up check-in consultation around two weeks after the session.

Aftercare

Avoid lying down or tilting your head forward for the first 4 hours. For the first 24 hours, skip intense physical exercise, saunas, and very hot baths. During the first week, avoid massaging the treated area, postpone facial treatments, and apply sunscreen when going outdoors, this is especially important around the delicate eye area.
