No, no, no, no, no. Girl has good skin, you gotta give her that. But I am a board certified dermatologist and the message here is don't be basic. What do I mean by this? So follow along. Our skin is acidic. That means the PH of our skin is usually around 4.5 to 5.5. We have on the surface of our skin something called an acid mantle. Acid is in it because it's acidic.
