I want to know the correct way to use moisturizing cream and the steps for application.

In the past, a single nourishing cream was enough, but nowadays there are so many types of creams that it requires a tremendous amount of knowledge, such as knowing which one to apply, what function each one has, and what to apply next.

Since my skin is extremely dry, I was immediately drawn to the word "moisture," so I always use a moisturizing cream. At first, I only applied the moisturizing cream and didn't use any other creams. I thought that simply providing enough moisture would be sufficient. However, my skin continued to feel tight and dry, so I started asking around. Some said that moisturizing creams don't supply moisture but rather prevent it from evaporating, while others said I should apply an oil-based cream first before the moisturizing cream. I heard all sorts of advice. So, my conclusion was to apply everything! But I don't know the correct order. There is a whitening cream, so I'm not sure if I should apply that first, or the oil-based cream first, or if I should apply the moisturizing cream first and then the oil-based cream... I really don't know. I just apply whatever I grab first. Since this topic came up, I thought I'd ask a question. The creams I have are Black Snail Cream, Soothing Cream, Jasaeng Cream, and Moisturizing Cream. Could you please tell me the exact usage methods and application steps for each?
