A daily skin care routine has four basic steps you can do once in the morning and once before you sleep.

1. Cleansing: Choose a cleanser that doesn’t leave your skin tight after washing. Clean your face no more than twice a day, or just once, if you have dry skin and don’t wear makeup. Avoid washing for that squeaky-clean feeling because that means your skin’s natural oils are gone.

2. Serums: A serum with vitamin C or growth factors or peptides would be better in the morning, under sunscreen. At night, retinol or prescription retinoids work best. See our articles on the best face serums for every skin type and the best serums for oily skin.

3. Moisturizer: Even oily skin needs moisturizer, but use one that is lightweight, gel-based, and non-comedogenic, or doesn’t block your pores. Dry skin may benefit from more cream-based moisturizers. Most brands will label their products as gel or cream on their packaging.

See our articles on the best moisturizers for dry skin, oily skin, or sensitive skin, as well as moisturizers with sunscreen.

4. Sunscreen: Apply sunscreen with at least 30 SPF 15 minutes before heading outdoors, as it takes a while for sunscreen to activate. Darker skin tones actually need more sun protection because hyperpigmentation is harder to correct.

Choose products that fit your skin type and sensitivity, and remember to read the labels. Some products, such as retinol or prescription retinoids, should only be applied at night. See our articles on mineral-based sunscreens or sunscreens for darker skin.
