The best laser is CO2 laser. Don't bother with electrocautery for deep issues like syringoma as the damage is less precise and therefore more collateral damage.
Superficial lumps like skin tags on the other hand can easily be done by both electrocautery and CO2 laser without any scarring as well.
Your photo may actually be sebaceous hyperplasia, instead of syringoma but this is more for academic purpose as the photo is quite blur. But the gold standard is still CO2 laser.
