Clinique Smart Clinical Repair Wrinkle Correcting Face Serum with Hyaluronic Acid, Peptides & Retinoid | Anti-Aging, Hydrating & Firming Facial Treatment for Day & Night Skincare Routine

This is my favourite Clinique product. I have been using it every day in the morning for years, so it is hard to tell how much it improves the skin, but if I don't use it for couple of days I see the difference (I am in my mid fifties).I have a sensitive skin and I mostly use the Clinique products.
