“I love this serum. It’s the only vitamin c that my sensitive skin can tolerate. Along with other synergie skin products it helps to calm my rosacea and even out my skin tone.”
“This is my favorite vitamin C serum. I’ve tried lots but I be stuck to this one for the past two years as it’s the only one I have seen consistent result with.”
“Really love how gentle but effective this serum is. Even if my skin is feeling a little sensitive, it can tolerate Effica C. Smell isn’t as enjoyable as many of the other products but it’s certainly not offensive.”
