Is laser treatment the only solution for freckles and blemishes?

I have really severe freckles and blemishes.

To get rid of freckles and blemishes, you should go to a dermatologist and get a laser treatment.

Will this be the most effective? I'm also worried it might hurt.

You can manage it at home before going to the dermatologist.

I want to know the method. I want to know about a good cream for freckles.

Which product would be good to use?

Below is a product I looked up to buy.

How about this product?
