The key to an effective skin cleanser is a non-irritating, able to remove dirt and oil, and feel good on your skin. Sometimes the simple variety are more effective than high priced products. Here are some of my favorites:

Neutrogena Deep Clean Gentle Scrub ($6)- A scrub for more oily skin
Purpose ($13)- Gentle and effective
