With all the options on the market right now, from skin-specific cleansing agents to heavy-duty moisturizers, sleep masks to acne cures to blackhead-fighting face scrubs, your dopp kit is probably chock-full of products at this point, ready to tackle any facial challenge that might arise. And for good reason, since you never want to find yourself caught off guard with regard to your grill.

All this upkeep, however, can get pretty damn expensive. Which raises the question: What can be done to resolve your skincare woes without you taking another trip to the drugstore? As it turns out, the answer’s pretty simple—all you’ve got to do is pay a little closer attention to what you eat. Because when it comes to taking better care of your skin, what you put into your body is just as important as what you slather on it. And so we’ve paired four common skin issues with the diet tweaks that might help cut them off at the pass. Every bite counts, after all.

The Problem: The Desert’s Got More Moisture Than Your Mug

How to Solve It: Got particularly dry skin? Then the first thing you’re going to want to do is increase your intake of foods that are rich with omega-3 fatty acids. Found in foods like salmon, avocado, walnuts, chia, and more, these essential fatty acids can’t be made by your body, yet are needed to protect skin’s outer layer. Another key component you should be on the lookout for: fiber. It’ll help flush toxic chemicals from the body, which can cause dry skin from the inside out, so be sure to get your daily recommended dose.

The Problem: “Slick” Isn’t Strong Enough a Word to Describe Your Skin

How to Solve It: What a lot of people don’t realize is that it’s not just the amount of fat you’re eating that affects your complexion, but also the type. For those seeking grease relief, know that it’ll come in cutting back on saturated fats, like those in fat-laden meats like steak and bacon, as well as deep-fried foods. You’re better off replacing them with, you guessed it, omega-3s, which will help to even out moisture content and minimize skin inflammation. Also, try your best to minimize dairy, as a 2015 study showed a possible connection between high-dairy diets and an uptick in the hormones that control oil production.

The Problem: Acne Didn’t End With Puberty

How to Solve It: If you’re looking to handle a zit issue, it all comes down to sugar—that is, the glycemic index of the foods you’re eating. Low-glycemic foods, such as whole grains, beans, and nuts, release sugar at a slower rate, reducing outbreak activity by lessening insulin spikes in the bloodstream. Aside from sugar, however, it’s also in your best interest to take in a lot more zinc, which can be found in things like oysters, lean red meats, and pumpkin seeds, as well as selenium, found in tomatoes, Brazil nuts, and broccoli. Both have been shown to help with acne in time.

The Problem: Your Age Is Starting to Show

How to Solve It: Know those antioxidants everyone keeps talking about? Well, when your years start to make an appearance on your visage, then it’s time to start paying more attention to ’em. Vitamin E is one great option, found in things like avocado, almonds, and hazelnuts. Vitamin C is maybe the best one around, and you can get tons of it in fruits like strawberries, blueberries, and oranges. Side benefit: Vitamin C is also a key component of collagen production, so consuming more, along with increasing your protein intake, will help your skin remain wrinkle-free for longer. Oh, and once again, omega-3 fats can help here, too.

Overachiever, those ones.
