content: I started using this product about 3 years ago, having heard about it from a UK magazine. When it was first released there, it was a huge hit becoming sold out really quickly all over. I was thrilled to find that Target started to stock Boots products, including this one, so I tried it. It makes a real difference when applied morning and evening before a regular moisturizer (I use the Boots No7 Protect & Perfect Day Cream). My skin is sensitive to many different creams and make up, but I have had no problems with this product. I would highly recommend this for those heading into their 40s and 50s, who would just like to go a little longer without wrinkles and lines.
