Do I need transcutaneous or transconjunctival blepharoplasty and why? (Photos)

You will do great with a subciliary/transcutaneous approach, You have excess skin and excess fat which will improve. If your concern is having a scar, then just go ahead with the transconjunctival approach. It will still look good. I have done transcutaneous approach in skin types like yours and darker and the incisions heal very well due to their placement underneath the lash line. 

The trap here is thinking that removing a small amount of fat, and then a 'small' amount of skin by trimming is the treatment. It is not. There is protrusion of the fat for sure but you also have sagging of the skin and lower eyelid muscle unit that needs to be dealt with and suspended. All this should be done without changing the essential and natural shape of the eye. You should see someone with a ton of experience with this.

Transconjunctival lower blepharoplasty with eye fat repositioning +/- skin pinch is generally the safest method to address under eye aging changes with natural results.
