Would you use this every day?
If not, is there something she can use on a regular basis to clean her face?
If you ladies know, should she avoid any foods or anything for that matter that might cause this?
she can use any gentle cleansing wash n then Neutrogena's oil free Acne Stess Control 3 in 1. its a gel with salicylic aid 2% that works like a moisturizer. if the black heads r on nose only get them extracted once n then use this gel once everyday. it will keep them at bay.
i hav stopped using scrubs as i exfoliate daily with AHA/BHA now.
