I've used this French pharmacy serum for 7 months to treat post-acne marks—here's proof it *actually* works

Shannon Lawlor after using La Roche-Posay Mela B3 Serum for eight months.

I have a tumultuous relationship with face serums—but La Roche-Posay Mela B3 serum has, truthfully, stunned me. You see, my skin is oily, prone to acne and lives in a permanently congested state. On top of this, it is also very reactive and susceptible to hyperpigmentation. And, let me tell you, finding a treatment serum that deals with the above issues all at once is very difficult. 

More often than not, retinol serums leave my face dry, serums that contain exfoliating acids turn me a neon shade of red and vitamin C serums can leave me with irritation-induced bumps and breakouts. As a result, over the past few years I have found my happy place in a simple skincare routine that leaves hardworking serums out entirely. But more recently the acne-induced dark spots have been causing me increasing distress. As soon as I'm over the pain and turmoil of a breakout, I'm left with dark spots that take months (sometimes years) to fade—and I know that a serum is the most effective skincare product to help me in this situation. So, when I was introduced to La Roche-Posay's new serum at the start of the year, my interest was piqued. Now, after eight months of using it every single day, I have some very important insights.
