Moisturizers are a staple in every good skincare routine. While we've been told that separate day and night creams are a must-especially after a certain age-are they really necessary?

The answer is yes-and also no. Depending on what you're looking for in your moisturizers, you may benefit from switching up the cream you use during the day and before bed at night. However, it isn't a necesary step for everyone.

Day cream

When prepping skin for the day ahead, look for antioxidants like Vitamin C and Niacinimide, which protect skin against pollution and free radicals in addition to brightening the skin and providing protection against sun damage. Speaking of the sun, SPF is must every morning, and your moisturizer is a good opportunity to add in some UV protection. You also may want to choose a day cream with a lighter texture that can act as a base for makeup.

Night cream

Evenings are a great time to add in actives and try products with heavier textures, as skin repairs itself while you sleep. Retinol is great for all ages and skin types, though the active is also effective on its own as a serum or treatment. If your skin is dry but you also want to wear foundation during the day, trying a thicker cream at night over a hyaluronic acid serum may provide the hydration you need to skip a heavy cream or oil in the mornings.

Do you need both?

While you can certainly use two different moisturizers for day and night, it's all up to personal preference. If you prefer to have fewer steps in your routine, you may want a cream that does double duty. However, if you're already using separate SPF and serums, one moisturizer might be all you need.
