What Does Sugar Actually Do to Your Skin?

"Sugar gets broken down into glucose in our bodies, which raises our insulin levels," Dr. Tanuj Nakra, double board-certified ophthalmologist, cosmetic surgeon, and co-founder of

AVYA Skincare tells InStyle . "Insulin spikes are a major trigger for inflammation in our bodies. Chronically high sugar levels can also lead to diabetes, even autoimmune inflammation, which has catastrophic effects on multiple organs, 

The inflammation caused by high sugar intake can worsen a variety of skin ailments, the MD explains. Conditions like eczema, acne, and

rosacea can all be triggered by the ingredient, which can lead not only to further and prolonged breakouts and flare-ups, but also dull skin tone, and premature aging.

"Chronically high glucose levels alter the protein structure of our skin, with the breakdown of collagen and elastin," Dr. Nakra says. "This results in accelerated sagging and wrinkling of our skin."

But, if you're someone who generally eats a well-balanced diet, has clear skin, and only reaches for candy or chocolate every once in a while, your skin probably won't hate you for it. "An occasional sweet treat can be a reasonable indulgence," the MD confirms. "Truly rare doses of sugar won’t cause breakouts or wrinkles."

If you tend to notice your skin flare up around your period — and also get mean sugar cravings at that time — it's always good to keep in mind that if you're already dealing with a condition like acne or eczema, there's always a risk that any sugar can further provoke your skin when your hormones are already raging. "The process can become a vicious cycle, as sugar can worsen inflammation," he says. "Try your best to maximize sleep, eat a healthy diet, and exercise around the time of your period." Think of your skin like your mood around PMS: It's already irritable, thanks to hormones. Throwing anything else volatile into the situation probably won't help.

Regardless of your eating habits (whether or not your hormones are on 10) if you're noticing any of the effects of sugar consumption on your skin, thankfully, there are a few solutions. If you want to combat the issue topically, Dr. Nakra suggests using products that are rich in turmeric, peony, neem, and other active botanicals to soothe inflammation. Ingredients like niacinamide and vitamin C also stimulate collagen production, which can improve skin tone over time.

And making some changes to your diet is key for getting to the root of the problem. "Foods that are high in fiber can help slow absorption of sugar by the gastrointestinal system," Dr. Nakra confirms. "The best strategy is to avoid any processed foods with added sugar, and to enjoy a whole food diet."

If you've found that you can't completely kick sugar out of your diet, there's a good explanation for that.

"Our brains receive a large dopamine surge with sugar intake — dopamine is associated with pleasure, and is also the target of highly addictive drugs such as cocaine and methamphetamines — which produces an addiction to sugar," Dr. Nakra explains. "If you are constantly craving sugar, in the form of candy, chocolate, or Frappuccinos, for example, then it is likely you are addicted to sugar."

While the surgeon explains that there are no forms of sugar that are "good" for the skin from a medical perspective (yes, that includes unrefined brown sugar, coconut sugar, and maple syrup), there are still some better alternatives for anyone who wants to be mindful of the sweets they're putting into their bodies.

"Natural sugars found in plants and vegetables are absorbed much more slowly when consumed in the whole food form, because these sugars are generally complex carbohydrates and coexist with natural fiber," he says. Apples, raisins, and dates are all examples the doctor would recommend.
