Most acids have tiny molecules that rush into your skin too fast. That causes burning, redness, and on darker skin it actually creates brand new dark spots from the irritation. Mandelic acid is different. It comes from almonds and has a bigger molecule, so it sinks in slowly and evenly. That means it exfoliates your skin and breaks up dark pigment without causing the inflammation that makes things worse. It also kills the bacteria that causes breakouts, so you are not trading dark spots for pimples.
