By far one of the most-hyped launches of 2021 is Go-To’s Much Brighter Skin. A triple-threat formula with stable vitamin C, niacinamide and hyaluronic acid, the serum works to treat every skin concern in one fell swoop — from hydration to brightening and all-round glow. The milky consistency is delightful to wear, and it’s a great all-in-one option for those who want to simplify their morning routine.
