Can/should I put sunscreen on my incision site if I'm going to be exposed to the sun? I am almost 4 weeks post-op.

I no longer have stitches but my incision sight is still pretty promenade/visible. There isn't any open sores but but the scar is hasn't started fading yet. I'm going to the lake but going to try my best to stay in the shade at all times and going to be wearing a hat but just in case I was wondering if I should put sunscreen on the incision sight to prevent scarring? And if so, what type of sunscreen? Thanks!
