I got the Flawless Brightly Serum about a week ago. I've been following Dr. Sam on social media for a year now and am a big fan of her tips and knowledge about active ingredients. I am not a beginner at this. I was looking for a product that combined several active ingredients that I usually used to layer individually. With Brightly, that's what I found! One pump is enough for my face, neck and décolleté. The consistency is pleasant and absorbs quickly. So far, my sensitive skin has tolerated the serum very well. If it stays like this, it's definitely a long-term product that I wouldn't want to miss!
