What is the most effective freckle laser?

I have dark skin, but I don't have many blemishes.

I started having redness for a few years and recently I even got freckles.

I recently applied for Meladuce 5 times, at one-week intervals.

I tried it 5 times and if I feel like the effect is not enough, would it be better to get a different laser treatment?

Or would it be better to continue receiving Meladuce?

Can old redness make freckles darker?

Does heat on my face make my skin more flaky and affect its elasticity? Is it a good idea to get laser treatment for freckles once a week? I've also heard that if you do it for too long, your skin will become thinner. Is that true?
