Handbag leather crack?

I just bought this Gucci tote preloved. It is in absolutely beautiful condition…with the exception of this small mark on the bottom. I believe it is a very small crack in the leather. The leather has not lifted in the area, but it appears to be a crack rather than some other mark when magnified.

Not sure if I should be super worried about it? My only real concern is it getting worse and the leather actually coming off in this area, not so much worried about how it looks right now. I put a leather protectant on the area, but not really sure what else, if anything, I should do. I always fear discoloring the leather when applying products.

Curious for other’s thoughts. Here is a (super) magnified photo.
