Botox does indeed improve the results

Studies have proven that Botox 2-4 weeks prior to resurfacing (whether it be fully ablative or fractional) definitely improves the results of wrinkle reduction of the crow's feet, and likely the glabellar frown lines and frontalis forehead lines as well. This is becasue the skin is not moving as much during the post-resurfacing collagen replacement period the next few months. The new collagen is laid down in a smooth layer.

Using a prescription retinoid prior to resurfacing also improves results as does the pre- and post-resurfacing use of sunscreen every day.

Good luck!
