"Over the past few months, I've made the conscious decision to scale down my double-cleanse, multi-serum, most-definitely-excessive skin-care routine. While I've set aside a handful of my go-to products, this Trish McEvoy Beauty Booster Serum ($130) is one I'll never, ever part with. It's formulated with hyaluronic acid, dual-action peptides and antioxidants to minimize lines and hydrate the skin. It's completely changed my skin's appearance, gives an amazing glow (I'll even dab on a few drops on top of makeup) and keeps my complexion looking plump, healthy and radiant. It's a holy-grail, for sure." — SH
