Amongst a lot of AHA, this is one that many kbeauty bloggers swear by. I decided to explore its usage due to a prolonged outbreak caused by change in climates - specifically for my T-zone. It's been working wonders, keeping my T-zone under control. And I've seen how it causes developing white heads or sebum spots to go away after usage. I have sensitive skin and so far, the product hasn't given me any trouble. Just be sure to use suncreen as AHA is photosensitive.
