What are your personal skincare secrets? What are your first step products?

Lately, my skin has been feeling tight and sensitive after washing my face, so I've been trying out a few different products. I've finally found my go-to skin care product. It's a slightly acidic toner. When I apply it right after washing my face, it reduces my skin's heat and helps the next step absorb much better. I used to think all skincare products were the same, but after using this product, I realized that the saying "my go-to skin care product" is not without reason. But then I suddenly became curious. What are other people's go-to skin care products as their first step after washing their face? I'd love to know which one worked best for you: toner, first essence, or mist. It would also be helpful if you could share what you consider to be the most important criteria when choosing your current skin care product.
