I was not sure this product would actually work. I am 73 and was resigned to wearing my wrinkles around my mouth. That's the only area that really needed some good treatment. Thought I would give this a try. Substituted this Clarins product for the product was was u sing (it worked, just not good enough) and inside of 10 days, I could see a difference, and especially after I finished my morning ritual of skin care, priming, and minimal makeup. I am so happy I bought this product.
