I recommend the slightly acidic one.

I believe we should use a mildly acidic cleanser because our skin is delicate. Wouldn't it be better to treat it as if it were a baby's skin? First off, my skin is sensitive. Originally, I just used whatever foam cleanser I had at home. As a result, my skin texture felt strange; it was rough, and I thought I was getting some wrinkles. Wondering why my skin was like this, I asked around, and guess what? They told me to use a mildly acidic product. I was skeptical; aren't all cleansing foams just the same? But since so many people urged me to try it, I decided to give it a shot. Now, my skin is smooth and soft.
