Reviews Summary
Customers say this spot treatment works quickly on blemishes, often showing improvement overnight. Many reviews mention reduced redness and swelling after application. The green-tinted formula helps visually counteract redness. While most find it effective for quick results, some note a strong smell that lingers. Reviews indicate it works particularly well on fresh breakouts, though results can vary with deeper blemishes. Some users appreciate its gentle formula, while others report slower progress.

    Yes, it works!

    Firstly, why is this not a bestseller?

    Secondly, yes, it works! Almost instantly it reduces blemishes and stops any of those nasty spots we all get from progressing.

    I am SO GUTTED that they no longer have the Mandelic Acid Treatment in production because this works hand in hand and has been THE ONLY thing that helped with removing scars so quickly. Bring it back PLEASE.

    I have hormonal spots and PD- New fav in ance spot care

    Saw an ad for this and looked into it more. The ingredients looked good but I’m always nervous to try new stuff because I have sensitive and reactive skin, prone to dermatitis from random products. Let me just say, this has been amazing for me. I put it under my nose where I tend to get PD spots, on hormonal cyst acne they pops up, and any where needed, and have had no bad reactions. It does dry the acne area a little bit but that’s to be expected with these ingredients and daily use. I used it on a big, under the skin cyst. It made the cyst slowly go down and its stay was shorter than it would have been. I also tried using it under makeup and it didn’t make any skincare or makeup pill up. Highly recommend and will rebuy, and that will take a while because a little goes a long way.
