For more than a decade, the subreddit r/SkincareAddiction has attracted skin-care devotees from all over the web. Its 1.8 million members include amateurs and professionals, offering everything from tretinoin tips to wholesome memes and product hauls. There’s a positive community aspect to the forum, where online friendships can be formed based on something as simple as a dupe for a discontinued “holy grail” item. It also serves as a completely free (though not always accurate) resource guide for anyone looking to dive into an overwhelming world of intimidating-sounding ingredients to build an effective personal routine.
