"Warning: This Cure de Repos Gold Roll-Cit ($300) is a total splurge. Now that I've gotten that caveat out of the way, let me tell you that I've had this dermaroller sitting in my medicine cabinet for about three years. I had used it maybe five times total, but knew how expensive it was and couldn't part with it. Thank goodness I didn't, because this has become an integral part of my social-distancing evening skin-care routine. Dermarollering (also known as microneedling), for those who are curious, is a method used by aestheticians to help rejuvenate the skin and treat signs of ageing. The supertiny needles on these rollers gently puncture the skin, and while the injury is superficial and controlled, it triggers the skin's wound healing response to stimulate collagen production. So how do I use it? About once every three days on clean skin at night. I then apply my serum, followed by my moisturiser. It definitely doesn't tickle, but I wouldn't say it hurts, either — more of a gentle stink that quickly dissipates. Since I've started using it, my skin feels tighter and smoother and, call me crazy, but I feel like my products are more effective. This one is gold plated and meant to suppress bacteria growth, but you can buy more affordable options at a derm store." — Amanda Elser Murray, associate style director, Group Nine Media
