I had covid back in early March and it made my skin really sensitive and sore. Once it felt like it had recovered a bit in mid March I started using dermatica - this is what they prescribed Tretinoin 0.015% / Niacinamide 4% / Azelaic Acid 4%. I had some soreness, stinging and dryness which is what I expected. I only used it every 2-3 days and with Weleda skin food afterwards along with applying a 50spf daily. However in the last couple of weeks the dryness has intensified and over the last few days I’ve got these red patches that have appeared and my skin has got so sensitive and tender - I bought some la Roche Posay cicaplast and even that stings like a bitch. I’ve never had skin issues like this before. Dermatica say keep going but I’m worried. Im also on a long awaited spa day tomorrow and I’m supposed to be having a facial but I’m not sure I can 😠- any advice welcome please! Photo doesn’t show it that well.
