This is a good AHA formulation. It really brightens my skin, and helps fade away scars. I still like the cosRx BHA formula more so I will come back to it when I finish this bottle.

Very strong product. Do not use if you have sensitive skin. It takes time for you to build up the tolerance. Absolutely do not use if you have a patch of dry skin, it will irritate it sooooo much. I've only used this for 3 weeks (once a week), so I don't know the long term effects yet.

Smoother skin overnight, improvement in 2 weeks

WOW, I wish I had used this sooner! I have constant acne along my chin and jaw area – lots of clogged, under-the-skin whiteheads that never went away and occasionally, red, painful zits that would surface and then leave dark spots behind. After using COSRX's BHA power liquid for nearly a year and getting OK results – mostly on my nose and cheek area – I decided to try this out and was surprised that I could feel a difference the next morning! My entire face felt smoother, but it didn't feel dry or irritated at all. My chin, which had a couple of red bumps the day before, felt smoother and FLATTER! The red bumps eventually went away completely after 3-4 days of using AHA 7, and the resistant under-skin white heads are slowly coming to surface! I've been using it for 2 weeks daily at night with COSRX's Good Morning Low pH cleanser and Snail 96 essence, and my problem chin/jaw area is looking the best it's ever been, feeling less bumpy, and I'm having less breakouts. I expect this purge period to last maybe another 4-6 weeks, but so far I'm really happy with the results!

How to Use
  1. This product is recommended for use in the evenings only as it is highly concentrated. It is recommended not to use other AHA, BHA, exfoliating or vitamin C products in conjunction with this product.
  2. After cleansing, put a small amount of liquid on a cotton pad, and spread over skin - focusing on the troubled areas. Gently tap your fingers over skin to get the liquid fully absorbed.
  3. If you feel severe stimulation or the purpose is the removal of whitehead and sebum, rinse off after 4 to 5 minutes lightly with lukewarm water.
  4. If the product is being used as a toner, only use other essences and creams after the whitehead liquid has been fully absorbed into skin. In the morning following your skincare routine, ensure sun screen is used as the final step.
