Started acids with the AHA 7 Whitehead Power Liquid with no problems; it worked wonders.

“I hadn’t used anything before either and started with the AHA whitehead power liquid and had no problems. Worked wonders for my skin!”

The AHA 7 Whitehead Power Liquid stung them.

“Their AHA whitehead liquid stung me.”

Finds the COSRX AHA gentler and more effective than other AHAs they've tried.

“This is how I feel about Cosrx’s AHA. It’s gentler than other AHAs I’ve tried, but it’s also more effective.”

Even at once a week, the AHA 7 Whitehead Power Liquid covers their forehead in itchy little whiteheads.

“after a few days I developed a lot of little whiteheads all across my forehead and lower cheek area.”

Amazed: it cleared out congestion The Ordinary's glycolic toner never touched.

“I was using TO Glycolic then switched to CosRx AHA. It was like a vacuum commercial. My skin purged all the stuff that TO didn't touch. I was amazed!”

Finally cleared their closed comedones with the AHA 7 Whitehead Power Liquid over a slow, documented routine.

“Finally got rid of my closed comedones with COSRX AHA 7 Whitehead Power Liquid!”

The COSRX AHA cleared their closed comedones in two days, but they came back after two weeks.

“My closed comedones disappeared in 2 days using the Cosrx AHA, but then they returned after 2 weeks.”

The COSRX AHA smells like sweat but works effectively on their skin.

“for me it's no big deal because the smell fades pretty quickly plus CosRX AHA works effectively on my skin.”

Prefers the COSRX AHA to the harsh Mizon; can use it every other night with no issues.

“I prefer Cosrx. I found the Mizon too harsh on my skin”

Found the COSRX AHA gentler than Mizon but still too rough for daily use.

“I switched over to COSRX (had a bunch of samples from Jolse orders) which was somewhat better but it was still too rough for every day use”

Seven months of daily COSRX AHA: likes it a lot, but results plateaued and it burns on popped pimples.

“I have been using the Cosrx AHA since July 2015 on a daily basis (for about 7 months) and I like it a lot, but my results have sort of plateaued.”

Won't rebuy the COSRX AHA; prefers the Mizon AHA and its smell.

“I won't buy the CosRX again - I like the Mizon much better.”

Found the COSRX AHA's effects slight over a long period and dislikes the smell.

“I don't like the smell of the CosRx and found it to have only slight effects over a long period of time.”

The COSRX AHA smells awful and gave them painful pimples that won't go away.

“It purged me pretty bad, and like not little whiteheads but like pimples that hurt and are not going away at all.”

Completely banished recurring jawline bumps; their top product of the year.

“invisible bumps on my jaw line that would slowly fill up and expand until I caved and drained them. NO MORE! This has completely banished them”

The COSRX AHA broke out their extremely oily skin, which cleared once they stopped.

“Pretty sure it's not the "purge" it does after starting to use it because I spaced my usage of it for about 3 weeks”
