My 14 y/o cousin has been having problems with pimples and blackheads. She tried different pinoy herbal solutions but ended up having dark spots on her face. Can you recommend something that can whiten or lessen the appearance of dark spots and pimples?

Back in high school I had an acne outbreak. I guess that was part of puberty. I had sessions of diamond peels and after about 5 sessions, my face cleared and my pores tightened. Applying harsh chemicals will only worsen the situation. She should use mild soap and water. Eliminating oil and dirt on skin will help a lot.
