If you don't want your daughter to take Accutane that is fine. There are other options. Squeezing out the sebum is NOT one of them as this will ultimately lead to scars and divets in the skin, which will then have her suffering from acne scarring. Not a good plan. Discuss other options with your dermatologist for topicals and oral meds. OTC products are not going to be strong enough in this case.

It is always best to seek treatment with a dermatologist. Depending on the severity of your daughter's acne, there are multiple topical and oral medications that can be tried before proceeding to Accutane. A topical prescription retinol and oral antibiotic can be very effective. There are multiple treatment options that should be exhausted before proceeding with Accutane.
