I've been using the PSF Gentle Foaming Cleanser since I got it from the Black Friday sale. It's more expensive, but I really like it. I only use it once a day (I use a Clean and Clear cleanser at night) and I have used very little. I can see it lasting a long time. You might check out the formulation and see if it might work for you.
