Estee Lauder's correcting pen for facial lines and wrinkles (there is another one specifically for lips) got the worst score in a French magazine's review of a range of different skin care products. I think the problem with this product is that it is too complex for its own good. Ultimately it raises expectations that it doesn't deliver on. Perfectionist Correcting Concentrate is really a light diffuser. YSL's Touche Eclat does a similar job of making lines seem less obvious. And, of itself, that's fine. The trouble with the Estee Lauder pen is that it promises to improve the skin with a complex concoction of things that begger belief, such as an ingredient that communicates directly with the skin's cells. That just takes the pen idea too far.
