I've used Skin Medica products for 10 years; I was excited to find a cheaper option,, and the website advertises original products. So, I placed the order during a special promotion. I did not need the product within 30 days. After using it for 5 days, I experienced chemical burns. The company response was that this is not an uncommon response, they did not provide a refund. So they do not stand behind their products. Alert " A Chemical burn is a common reaction from their products" Do not buy!
