Query: Used to love this product.

I used to love this product. Then about six months ago, La Roche Posay changed the formula. Now there is an "anti-relapse" ingredient which wasn't there before. The whole consistency of the product has changed, the way it works changed, and when you begin using it, it no longer effectively spot treats acne. I used to be able to use this product and get results within a day! Now, if I use this product, my acne gets worse. I wish La Roche Posay was still offering their original formula, which was so effective and smelled great.
