Hi there, I have a question about retinol use during pregnancy. I have been using Kiehl's retinol skin-renewing daily micro-dose serum for the past 2.5 months and I just realized that I should avoid using retinol during pregnancy because of the possible risk of birth defect. I am freaking out now and blaming myself so much for being so careless. I am 38 weeks pregnant. Does anyone have a similar experience? Can anyone give me some advice or put my mind at rest a bit? Thanks!
