Picosure Focus alternating with Cynosure IPL or just use one of the two, and timeframe?

Initial recommendation 4 sessions of Cynosure IPL in 4 mths, and then 1 every 3 months for a year. Or use Picasure Focus. Then I was told it would be better to have 8 sessions in 8 mths alternating between the two. Total of 4 Cynosure IPL and 4 Picasure Focus. The first recommendation would be 8 sessions over a 16-month period, where alternating them would be 8 sessions in an 8-month period. I am 56 years old with average skin imperfections. I will also be getting botox. Thouhts
