Leaves your skin...
I have been using this product for a week and I am really happy.
After the use you can feel your skin soft and deeply cleansed, it has fragrance but being a wash off treatment I don't see it as a problem and it leaves with a really fresh smell. Most cleanser has around 6.7 ounces of product, but this has 13.5 ounces.
I would raccomend this for people on a budget with combination/oily skin

I love this cleanser so much! I have oily, acne-prone skin and this helps clean any oil and dirt on my face without breaking me out. My skin always feels nice and clean. I've tried many other cleansers and nothing has worked as great as this does. I have been using this for years and this will always be my go-to. If you have dry skin, do not use this as it may be too drying/stripping.
