I'm 24 weeks pregnant and I just used a new night cream I bought: Cetaphil Hydrating Night Cream. It didn't seem to mention any retinol etc. My face started feeling a bit warm after about 40 minutes so did a Google and it turns out it does contain a retinoid. I washed it all off but now I'm panicking that it might have harmed the baby. Someone please tell me I'm being crazy and 40 minutes use will have no impact 🙃
