I have sensitive skin that scars easily and my sun damage has been starting to show since i hit 30s. This is the only VitC i have used that has removed discolorations quickly. I get cherry angioma looking spots on my face occasionally and this VitC makes them disappear within 2-3 weeks as is they were never there. Its also not tacky (unless you apply too much). Not sure whu someone rated this a 1; it truly is amazing. And according to skinskool its a 98% match to skinceuticals, but i hear that one is tacky. 🤷🏼‍♀️
