Precautions after removing freckles and blemishes spread across the face

I am worried because the areas where my freckles and blemishes started appearing seem to be getting wider. I am planning to get a proper laser treatment for them at Maypure this time, but what precautions should I follow after the procedure? I know that I shouldn't forcibly remove scabs once they form, so I am wondering if there are any specific precautions I should take when washing my face. I feel like I will need to apply sunscreen more thoroughly than usual after the treatment, so I would also like to ask if you have any recommendations for a regenerating sunscreen. I plan to follow your instructions carefully this time to ensure clear skin.
