No instructions came with the four products, so it was inconvenient to have to look up instructions on-line. More importantly, the eye creams do not absorb well despite my gentle rubbing in. I could never use these products during the day as they stay "wet" for a very long time. I have noticed no significant improvement to my under eye area with these products, so for me this is another product with lofty claims, but lack the results. May be a perfectly good moisturizer for night, but otherwise I am underwhelmed. I achieve better results with a less expensive drug store retinol cream.
