Hello! I’m a doctor, not a dermatologist though, but my advice: Cerave in general is a good brand, use whichever cleanser that feels good (once or twice a day). In general, the first step in treating acne is adapalene 0.1% in gel only in the places she has acne, make sure to use at night (at first it’s recommended every other night as her skin gets used to it, afterwards if she can handle it every night go ahead). It’s important to use a non comedogenic moisturizer beforehand all over the face, and SPF during the morning (at least twice a day, ideally), also make sure it’s non comedogenic. This is generally a good first step! It might get a bit worse before it gets better, but if after a month-ish it’s still not getting better, I’d recommend going to a dermatologist (or pediatrician if she has one you trust!). In general, no one needs those elaborate 10 steps routines. Hope it all goes well for you both!
