How To Build A Skin-Loving Cup Of Coffee, From Research

Derms, estheticians, and skin care experts will always tell you that maintaining healthy skin begins with what you consume—and that starts first thing in the morning. Whether you drink coffee, matcha, or chai, what you put inside the cup can influence your skin.

The general limit for daily caffeine intake, according to the FDA, is 400 mg1 (i.e., about four cups of coffee a day is shown to be safe for healthy adults). However, if you know your caffeine metabolism runs on the slower side—or drinking four cups makes you feel jittery—cutting yourself off at two cups a day is probably a better idea.

The goal here is to limit the side effects of consuming too much caffeine2, which include inadequate hydration and trouble falling asleep (just to name a couple)—both of which can influence your skin.

If you're going to put creamer or milk in your coffee, you should try your best to be mindful of which product you choose. For example, in one study noted by the American Academy of Dermatology (AAD)4, those who consumed skim milk were more likely to experience breakouts than those who consumed other forms of milk or alternative plant "milk." 

The AAD notes a theory that hormones in the milk put one at a higher risk for breakouts. Milk consumption has also been linked to an increase in a hormone called IGF-15, which stimulates oil glands to produce more sebum. This has the downstream effect of an oilier complexion, which can lead to congested pores for some.

If you're going to drink caffeine every day, why not make it helpful for your skin rather than just minimize the negative impact? One quick way to do so is by adding a scoop of collagen powder to your coffee.

On its own, collagen has been clinically shown to support skin elasticity and dermal density6; however, one lesser-known benefit of taking collagen supplements is their ability to support the skin's hydration levels and combat wrinkles7.* 

Our pick? The mbg beauty & gut collagen+. While this unflavored powder does contain 17.7 grams of hydrolyzed collagen peptides, it packs a punch with additional skin-loving ingredients, too (making it a real bang for your buck). 

According to the AAD, a low glycemic index dietary approach may lead to clearer skin. This means opting for less sugar when possible (instead, opt for slow carbs with fiber from fruits, veggies, whole grains, legumes, etc.) and choosing small amounts of natural sweeteners when you do want to sweeten things up.

Contrary to popular belief, moderate caffeine intake itself doesn't actually impact your overall hydration levels, studies reveal8. However, if you're constantly reaching for cup after cup, you're more likely to skip a glass of water.
