Skin care

Hi mommies! I need recommendations ASAP please!!!

I’m pregnant with my 2nd child and I’m getting really dark pigmentation on my face.... any recommendations on skin care? I’m 29 years old and my face is just getting horrible in my opinion.. my obgyn recommended “ SKIN BE++ER” even tone serum but I’m kind of on edge due to pricing being high and not seeing a lot of reviews from real people besides from doctors and nurses and celebrities.....

Thank you!🙏🙏🙏🙏🙏
