TIAM - Ruthieandskincare review for My Signature Red C Serum

Very impressed with results to fade PIH with this serum. reduced 60% of my hormonal acne marks in 3 weeks as expected of Pure LAA and glutathione. However this is quite a potent vit C, caused mild burning/warming sensation for me on the first couple of application until my skin got use to it. Smells like burnt childrens strawberry cough syrup.
