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.

Can I use two different moisturizers at the same time?

Adding multiple layers of moisturizer to alleviate dry skin is not the same as switching to one with a creamier consistency. Using thicker coats of moisturizer will only cause you to go through your moisturizer faster (and waste your money). If this is what you're doing, it's clear that your skin needs something else.

Should you use different moisturisers?

The general rule of thumb is that thicker ointments help dry skin, medium-density creams are best for normal to combination and lightweight, fluid lotions work well for oily skin. Dr Jinah Yoo recommends: For sensitive skin, choose a fragrance-free and hypoallergenic moisturiser to reduce irritation.
