Which peel is better for acne: glycolic or salicylic acid?

Which peel is better for acne glycolic or salicylic acid, submitted image.

I have pretty bad skin, with painful zits and giant bumps throughout my cheeks and chin. I can't put makeup on them because they look gross. I started doing some research on the Internet and found out that glycolic and salicylic acid can help clear acne. Can you please tell me which one would be better for my type of skin and acne? I'm really frustrated about it. Thank you!
