We’re all master multitaskers in our daily lives. Isn’t it nice when our skin care products can do the same? Not only can 2-in-1 products save us time, they can also save space in filled-to-the-brim medicine cabinets and bulked up cosmetics bags. Below, we share three dual-purpose serums that are must-haves in your skin care arsenal.

The fast-absorbing formula helps reduce signs of aging—think: the look of wrinkles and fine lines—while hydrating the skin. Skin will feel smoother, tighter, and more firm. To use, gently pump a small amount onto fingers and massage onto your face and neck twice daily.  Garnier Ultra-Lift 2-in-1 Serum + Moisturizer, $16.99KIEHL’S PRECISION LIFTING & PORE-TIGHTENING CONCENTRATE“Two is better than one” holds true for this serum that works to visibly lift the appearance of skin and help redefine the look of facial contours, while noticeably tightening the appearance of enlarged pores.
