Do you all apply retinol and vitamin C products separately, with a time gap between them?

Lately, I've been wanting to manage my pores and blemishes at the same time, so I recently bought a new retinol cream and a vitamin C ampoule. However, I heard that using these two ingredients together can irritate the skin, so I'm worried about how to apply them. To see results without irritation, would it be safer to completely separate the time slots—applying vitamin C in the morning and retinol during my evening skincare routine? Or should I just alternate them every other day? I'm curious. If anyone has found the perfect routine using these two together, please leave some advice in the comments! The weather is getting really hot, so please take care of your health everyone!
