When applying skincare products, should one wait a specific time before applying the next product?

Thanks very much for this question. When it comes to your active products (ie your serum, moisturiser and sunblock), generally no, it’s not necessary to wait. I would, however, wait 10-15mins before applying my make-up. There are a few exceptions, when it comes to some prescription products, but generally, with other products, waiting is not necessary.
