I don't wear make up, and my cleansing routine is just a bar of soap. Occasionally a bit of Olay face cream! I'm 41 and noticed my skin has got quite dry, and is starting to look a bit like crepe paper! My eyes are looking pretty dark and sunken too😲 I'm assuming this is a lack of collagen?? So I'm looking for recommendations for a good collagen face cream please! TIA
