josh rosebrook hydration boost concentrateSo I was pretty skeptical of this product when I first came across it, mainly because it's quite expensive for the amount of product you get. However, I took a look at the ingredient list and I would say this is akin to a "shot" of antioxidants for your face! It contains a blend of hyaluronic acid and a variety of plant-derived antioxidants. I only use two drops for my face and my skin drinks it right up. The brand is vegan, cruelty-free, and makes products in small batches. I appreciate that, too.
