Easy to apply. No scent. Leaves skin feeling hydrated while waiting for the acid to work between steps. Other than that... I didn't notice much of a visible improvement in my skin when I first started using this. I purchased this for acne breakouts on my cheeks from clogged pores. I started with two times a week. The first month in, I noticed very tiny bumps identical to milia on my cheeks which I've never had before along with a several patches of acne that cropped up on my cheeks and jaw. I didn't notice any irritation other than that side effect. I'm unsure if this was part of the "purging" stage... but the bumps did clear up when I slowed my usage to once a week.

I will say that using it once a week, I've noticed that the pores in my cheeks are visibly clearer and smaller in size. I will try this again unless I have another issue.
