Build morning and evening routines and distinguish a useful addition from duplication.
Skin anatomy: the epidermis sits above the dermis, with follicles and glands at different depths. Location explains a skincare target; it does not prove that a product reaches every layer.

Core ideas before application
Does serum tell you the product's function?
No; check its ingredients and purpose. Format alone does not tell you whether it hydrates, exfoliates or serves another role.
Where does sunscreen go in the morning?
After skincare and before makeup. Apply it as its own layer as directed.
Locate ultraviolet and visible light within the spectrum. This is not a sunscreen protection test; protection must be assessed from product data and testing.
