When I got this sample I thought it would be too small to make up my mind about the product. In the end, it was enough, first it little goes a long way since its a serum, and second this product is really good and in a few tries one can already feel a difference. I enjoyed it a lot, it feels very light when applied. It is also one of those few products that once you use it, you truly feel a difference in your skin.
Would I buy this based on the sample? Yes, I am interested in buying this product, it seemed effective even in such a short time use.
