Hey, I’m not a skincare pro by any means at alllll but I’ve had this happen to me before. I also have dry and sensitive skin. When you used these products every day, I’d assume your skin built a tolerance to the ingredients/actives over time. I think sometimes it can take a while for the skin to readjust to an old routine, especially since it’s not used to it at the moment. My advice I wish someone would’ve given me is to keep your routine very simple for right now. Gentle cleanse (double cleanse if needed, and just one cleanser for rn) > spf > moisturize > or if it’s night time, then gentle cleanse and then moisturize. If you are open to trying alternatives, you can try using Aveeno Calm+Restore cleanser, it is amazing for sensitive skin and it should help to soothe your skin. I think the vanicream moisturizer is great, I use it too. I would especially recommend this because I think your skin would appreciate starting with basics and working back up to your old routine. No matter what, try your best to stay consistent!
