You know that meme about how everything that was punishment in your childhood is now reward as an adult? Going to bed early, eating vegetables, alone time. And, of course, vitamins. I\u2019m not talking about the Flintstones chewables of your childhood, though, but the latest skin-perfecting supplements, which claim to fix your acne, smooth your scars, fade your redness, and more. A magic little pill? Sounds too good to be true. So as your resident skeptic, I went to the experts to find out, once and for all, if these fancy vitamins really do work wonders on your skin, or if the capsules are just another kitchen-cupboard fad. First, What Are They? Despite their Instagram-worthy bottles and packaging, these \u201cbeauty supplements\u201d (as most brands refer to them) are essentially just...gussied-up vitamins. And you can find them virtually everywhere, with labels boasting benefits like \u201cclear skin,\u201d a \u201chealthy glow,\u201d and the ability to \u201cremedy\u201d dark circles. Sephora, for example, currently offers 106 of these ingestible products with prices ranging from $10 to $210, making it possible for virtually anyone to get in on the trend. But if you look at the ingredients list for most of the best-sellers, they aren\u2019t filled with super-secret sprinkles of magic\u2014they\u2019re high in all of the usual suspects, like magnesium, zinc, calcium, and vitamins C, A, and E. \u201cMost of these trendy supplements are really just modified versions of daily multivitamins,\u201d says dermatologist Mona Gohara, M.D., associate clinical professor at Yale University. \u201cAnd though it\u2019s true that vitamins play an important role in your skin health, most people already get the nutrients beneficial to skin from the foods they\u2019re eating.\u201dSo, What\u2019s the Point?Theoretically, that these beauty supplements would offer something you can\u2019t or don\u2019t get in the standard American diet or via a daily multivitamin: skin-boosting ingredients like collagen, alpha lipoic acids, milk thistle extract, and selenium, just to name a few of the hundreds of \u201cobscure\u201d natural ingredients across beauty supplements. But there\u2019s a reason your multivitamin doesn\u2019t contain the same ingredients: Your skin\u2014and, for that matter, your body\u2014probably doesn\u2019t need them.\u201cThere\u2019s no real evidence that shows a multivitamin or a beauty supplement plays a role in your skin\u2019s health when you\u2019re an otherwise healthy person with no vitamin deficiencies,\u201d says Dr. Gohara, adding that unless you\u2019ve been tested for a deficiency, \u201cthey probably won\u2019t do much for you.\u201d Plus, your body absorbs nutrients better from food than it does from pills, she says, which means even if you do ingest a bunch of, say, collagen or milk thistle, it\u2019s unlikely that those nutrients\u2014which haven't even been proven to help your skin when taken orally\u2014will survive digestion in high enough quantities to then travel through your bloodstream and make an impact on your skin.Then, Do They Really Work?Despite all of the above, it\u2019s still tough to definitively say. \u201cNobody\u2019s diet is perfect every day of their life, and not everyone\u2019s gut absorbs vitamins and nutrients the way it should, so you can put all of the best things in your body and still have low vitamin levels, and, in turn, skin conditions,\u201d says dermatologist Rebecca Tung, M.D., associate professor of dermatology at Loyola University in Chicago. \u201cYou may absorb things great in your 20s, but not as well in your 30s, which is why supplements can actually be really helpful at filling in the \u2018gaps\u2019 of your diet,\u201d says Dr. Tung. \u201cVitamins, at a basic level, help regulate the immune system, which helps minimize inflammatory conditions, like acne, rosacea, and dermatitises. So it\u2019s possible that some of these supplements can improve your skin if you have low vitamin levels.\u201d Of course, unless you get tested by a physician, you\u2019ll never know if you\u2019re truly deficient\u2014and it\u2019s not a good idea to start popping a bunch of supplements before talking to your doctor. They can have negative effects.\u201cSome vitamins, like B and C, are water-soluble, meaning your body will pee out the excess it doesn\u2019t need,\u201d says Dr. Tung. \u201cBut other vitamins, like A, D, E, and K, are fat-soluble, meaning they can accumulate in the liver and cause damage if you take too much.\u201d So if you do plan to try a beauty supplement, make sure you test only one brand at a time, especially if it contains similar ingredients as your multivitamin.When Will the Results Kick In?\u201cVitamins are only work for as long as you take them, so you need it look at this as a long-term commitment,\u201d says Dr. Tung, noting that you should start to see results within 4\u20136 months of continual, daily use\u2014that is, if you end up seeing results at all. (I know, I\u2019m sorry, but there\u2019s no one-size-fits-all approach to health and skin, and your results will definitely vary.)Still, as long as you\u2019re not going overboard with the doses, \u201cit can\u2019t really hurt to try,\u201d says Dr. Tung. \u201cI don\u2019t think a supplement pill will be a messiah for your skin, but it\u2019s a pretty harmless option to explore.\u201d Of course, because supplements aren\u2019t FDA-regulated, I urge you to choose a reputable, well-known, review-backed brand (like the four best-sellers at the top of this story) for the sake of your health. Sure, they may end up not working, but at least they won\u2019t hurt your insides while you test them out, right?
