okay so i wrote a review saying it was gritty but that’s because i was applying it per their recommendation. it’s itchy and irritating because it’s basically super concentrated bursts of ascorbic acid powder sitting on your skin which is bound to irritate even pretty resilient skin.  however, i started using it over an essence (i use the cosrx snail mucin) before the essence has been fully absorbed, which helps the suspended vitamin c powder dissolve. less irritation that way! i’ll be able to use up the tube now. 

I love this product. its great on dry skin full of tingling moisture keeps your skin feeling hydrated all day long

It's my first trial of this product. I use it before the HA product , I gues it is effective as their other Vit C products . Don't know yet!

It’s make my skin so red and sensitive 

Oxidised after the first use, and turned me patchy orange every time I used it (face and hands). Also, it smelled like tan. I tried using it multiple different ways to counteract the orangeness - over serums, over moisturiser, using it only at night etc. No luck, unfortunately. Washing hands after use does help prevent them from oxidising so they don’t turn orange. Also, the texture is so gritty and unpleasant.
