Is CO2 laser effective for mild upper eyelid hooding?

I am 45 years old and I have mind upper eyelid hooding. I think it is aging me a little, but I am not yet ready to assume the risk of an upper blepharoplasty (i.e, scar, possible asymetry, complication). Is CO2 laser of the upper eyelids effective in retracting the skin of a mildly hooded eyelid? How long does the effect last? I would consider surgery in the future when the hooding gets significant, but not at this time. Thank you
