Spend more than three minutes talking to any dermatologist, and they’ll inevitably start raving about three things: 1. Wearing sunscreen every single day until the moment you die, 2. How Accutane is an actual miracle drug, and 3. Why everyone should be slathering vitamin C on their face every single morning. Because unlike retinol (the other constantly derm-endorsed skincare product), which can cause irritation and flakiness in the majority of people for the first month, vitamin C is a skin-perfecting ingredient that’s tolerated by almost all skin types.

Unless you’ve got ultra-sensitive, ultra-reactive skin (lookin’ at you, rosacea peeps), you should be adding some vitamin C to your skincare routine, stat. Just massage a few drops of the serum over clean, dry skin in the morning, wait a minute for it to sink in, then apply your moisturizer, sunscreen, and makeup, like usual. It’s not an overnight miracle worker, but derms agree that you’ll start to notice a difference in your skin’s appearance within a few weeks of consistent use. Which is almost the same as instant gratification, right? Right. SEE THE PRODUCTS.
