Curious about the order of applying oil and effective tips for using oil according to skin type?

I am currently following a skincare routine in the order of toner, essence, lotion, and cream, but I am planning to add a face oil to enhance hydration.

In this case, would it be better to apply the oil alone before the cream to allow it to absorb, or would it be more effective in terms of absorption rate and long-lasting hydration to mix an appropriate amount with the cream?

I would also like to know the optimal methods and precautions for using oils according to each skin type, such as dry, oily, and combination skin.

If you have any expert tips on how to perfectly address inner dryness without disrupting the oil-moisture balance, especially during the changing seasons or winter, please share them in detail.

I would appreciate it if you could provide the order of oil application and a customized guide for different skin types.
