I've been using this for a month and I feel like this was what I was missing in my routine!! I had a pretty intense routine before using it - mainly targeting brightening and keeping my dehydrated skin happy, but I could never quite get my skin at a "flawless" texture.  After using OST for about about week I started noticing the small little white heads on the sides of my face flatten out! Even my BHA/AHA products couldn't do that! Now my skin looks smooth and is actually pretty good with a few white heads here and there on my cheeks. Warning: this product can be on the drying side with daily use, so I recommend every second day. Unfortunately I can't make claims on fading scars since I didn't have much to begin with but I did notice a slight improvement. Also if you're looking for a "whitening" product this hasn't made me noticeably lighter despite pairing it with brightening serums and niacinamid containing products...Despite my review not being life changing, for some reason I just like how my skin has been looking on this product in conjunction with everything I have right now!! I can't complain with the price either! Give it a try if you're thinking about it (:

PS...

- Store it in the original box in your fridge to keep it fresher longer

- Before applying the rest of your products wait 10-30mins after applying it

- I prefer to use it as my very 1st step after washing my face

- Best to use in the night! Or pair it with a strong SPF for the day
