This is my personal holy grail. It's life changing. I'm totally serious. I used to have really bad cystic acne on chin. Nothing helped - not even products containing retinol prescribed by a dermatologist. But this toner really does a huge improvement. Ever since I bought this toner, I don't have painful big pimples that leave scars. My skin is almost clear. I'm slightly disappointed that this product doesn't do much with my melasma and post-acne dark spots but there are other AHAs focusing on that. I also tried to apply a tiny amount on my hairline where I have flaky spots from seborrheic dermatitis and they're almost gone. Also, the price is amazing for so much volume.

My tip: Give your skin at least 2 weeks to get used to this toner. And don't forget to wear a sunscreen.

I bought this toner before I learned that glycolic acid and sensitive skin were NOT a match... I had used it for a decent while and I liked it for the mild exfoliating it did, and it did seem to help a little with acne. However it just didn't work for my skin at all because glycolic acid is too sensitizing for my skin. My skin would always look worse then it did before I used it; bright red and slightly tingly.

Since Glycolic Acid is one of AHAs, it sure does it great job in exfoliating my skin (chemically). I used it in my PM routine right after double cleansing,, using a cotton pad. It does irritates my skin at first, I dilute it with some water then it's good to go! It helps me a lot with my skin texture and complexion. For sensitive skin, it might be quite stinging so you have to introduce it slowly and gently starting with few times a week and careful not to over exfoliate your skin. Another tips is wet your skin with a splash of water and wipe em using your hand so that the water doesnt get removed entirely (not soaking wet please XD), that way you don't have to dilute your Glycolic Acid. It doesnt take longer than few weeks, slowly but surely, my tiny bumps on forehead got cleared out. Make sure to listen to your skin. If it irritates you, stop using it.** Dont forget to always wear sunscreen (compulsory)**.

Well, for best result, after using exfoliating toner, top it with any hydrating toner :)

Or maybe top up with any moisturizer (after hydrating toner) with for skin calming purposes - Avena Sativa (Oats), or Centella Asiatica, for skin barrier - Ceramides, Triglyceride. For reference, https://blog.reneerouleau.com/dry-tight-irritated-skin-your-moisture-barrier-might-be-damaged/

As always, it entirely depends on your skin too :)

I started using this product to try and brighten my complexion, while also trying to target small areas of hyperpigmentation from previous breakouts. I use this every other night (alternating with lactic acid) after cleansing to make sure my skin is completely clean and fresh. There's a slight tingle when I apply it, but I haven't experienced any dryness, redness or irritation from this product.

It did seem to speed up the healing process after I attacked a pimple (yeah, I know...), and if I do feel a pimple rearing its ugly head underneath my skin, applying this product does seem to prevent them from emerging completely (hooray!). However after three months of daily use, I haven't noticed a major change in my complexion/hyperpigmentation.

PROS:
- No irritation, other than a slight tingling
- Controls pimples and reduces their appearance
- Leaves your skin feeling clean and refreshed

CONS:
- Haven't noticed a major change in my complexion or hyperpigmentation
