I heard that mildly acidic cleansers aren't effective.

I saw on the internet that our skin is already acidic due to sebum secretion.

I heard that just because you use a mildly acidic cleanser doesn't mean it's effective.

I've already stocked up on so many mildly acidic cleansers because everyone kept saying I needed to use them...

It's a shame, but I'm wondering if I should just let it go without using it. I thought my sebum production was high because it's summer, but...

It's absolutely horrifying to think that it wasn't that, but the sebum just kept clumping together because it wasn't washing off properly.

Please recommend a cleanser that washes well and effectively!
