Please choose the correct ending to complete the given sentence: Youth: [header] How to get rid of acne quickly and cheaply [title] Wash acne-prone areas frequently and gently. [step] Using a gentle, non-soap cleanser twice a day is likely the most powerful weapon in the battle against acne. Another key tip: don't be overzealous.

Ending1: You don't want to scrub your problem areas too hard. Rather than scrubbing for several minutes, use a gentle shampoo. Ending2: Wash consistently, but without scrubbing, as this can actually make acne worse. [substeps] Favor a cleanser that dissolves during washing, as these are less abrasive. Ending3: As with acne-prone skin, you will hardly be able to tell the difference between these cleansing techniques. Take a shower or bath in the morning and squeeze out any excess water, and try to moisturize yourself and your skin in the evening. Ending4: Try to clean the area daily and scrub it monthly. This will help smooth your skin even quicker and protect your area from irritation and subsequent acne.
