The results of treatments for expression lines that you’ll see here are not renders or generic photos, but real cases of patients treated in my clinic in Bogotá between 2023 and 2024. Each before and after of expression lines was documented with photographs under controlled conditions and verifiable follow-up. In the last two years we treated more than 450 patients with expression lines, with a 96% satisfaction rate and complete elimination of dynamic lines after the botulinum toxin protocol. Below you’ll see 5 representative cases with patient profile, treated area, number of sessions and evolution of results.

If you’re tired of seeing miracle cream promises on social media, here you’ll find real documentation with verifiable numbers.
How to correctly interpret photos of expression line treatments
Before showing you the cases, you need to know how to identify legitimate vs manipulated photos.
Professional photography conditions: Same controlled lighting in all shots. Same calibrated camera distance. Same facial expression (relaxed vs dynamic). Same time of day. Recognizable clinic background.
What to look for in legitimate photos: Same facial expressions. Continuity in makeup. Date metadata. Most importantly: comparison before/after with same expression.
Red flags for fake photos: Drastically different lighting. Different pose. Obvious Photoshop. No dynamic comparison.
All photos include before/after comparison. Lines don’t lie. A “before” with marked lines and an “after” without them is real difference.

Botulinum toxin type A works by blocking acetylcholine release in neuromuscular junctions. When injecting toxin, it binds to receptors in nerve endings, preventing the signal that makes the muscle contract. The result is temporary muscle paralysis, eliminating dynamic lines.

| Mechanism | Inhibition of acetylcholine release |
| Duration | 3-6 months |
| Effect | Reversible muscle paralysis |
