Does Drinking Soda Give You Pimples? What Research Says

Yes, the evidence points to a real connection between drinking soda and getting pimples, but it is not a simple one-to-one cause for everyone. Research consistently links high sugar intake and high-glycemic diets to increased acne severity and frequency. The mechanism involves your blood sugar, insulin, and hormones, which can trigger the skin changes that lead to breakouts.

What Does the Research Actually Say About Soda and Acne?

Studies have found a clear association between frequent sugary drink consumption and acne. Researchers have observed that people who drink soda regularly tend to have more acne than those who do not. This holds true across different age groups, though the effect is often more noticeable in adolescents and young adults.

This does not mean one can of soda guarantees a pimple. Acne is complex. Genetics, hormones, stress, and skincare habits all play major roles. Soda acts as a trigger that can worsen existing acne or make you more prone to breakouts, rather than being the sole cause.

The evidence is strong enough that many dermatologists now advise patients with acne to reduce sugary beverages as part of a broader treatment plan. It is not a cure, but it is a modifiable factor that can make a meaningful difference.

How Does Soda Trigger Breakouts?

The main culprit is sugar. A standard can of soda contains a large amount of added sugar, often in the form of high-fructose corn syrup or sucrose. When you drink it, your blood sugar spikes rapidly.

Your body responds by releasing insulin, a hormone that helps move sugar out of your blood and into your cells. High insulin levels trigger a cascade of hormonal changes. Insulin stimulates the production of insulin-like growth factor 1 (IGF-1), a hormone that promotes cell growth and division.

In the skin, IGF-1 causes your sebaceous glands to produce more oil, called sebum. It also encourages the growth of skin cells lining your pores. More oil plus more dead skin cells equals clogged pores. This creates the ideal environment for acne-causing bacteria to multiply, leading to inflammation and pimples.

High insulin levels also reduce the activity of a protein called SHBG (sex hormone-binding globulin). SHBG normally binds to and regulates testosterone. When SHBG levels drop, more free testosterone circulates in your body, which further stimulates oil production.

Is Diet Soda Just as Bad for Your Skin?

The research on diet soda and acne is less clear. Diet sodas contain artificial sweeteners instead of sugar, so they do not cause the same blood sugar and insulin spike. Some studies suggest a link between diet soda and acne, but the evidence is much weaker and less consistent.

There are a few possible explanations for a connection. Some artificial sweeteners may influence gut bacteria, which could indirectly affect skin health. The link between gut health and skin is real but not fully understood. Another possibility is that people who drink diet soda also consume other foods that contribute to acne, making it hard to isolate the effect.

Current evidence does not support diet soda as a major acne trigger in the same way regular soda is. If you are trying to improve your skin, switching from regular to diet soda may help reduce sugar-related breakouts, but it is not a guaranteed fix.

Does the Type of Soda Matter?

All regular sodas are high in sugar, but the exact amount varies by brand and flavor. A typical 12-ounce can contains roughly 30 to 40 grams of sugar. That is about 8 to 10 teaspoons. The American Heart Association recommends no more than 36 grams of added sugar per day for men and 25 grams for women. One can of soda can exceed that entire daily limit.

Colas and dark sodas may have additional effects. Some contain caramel coloring and phosphoric acid, though no strong evidence links these specific ingredients to acne. The primary driver remains the sugar content.

Fruit-flavored sodas are not a healthier alternative. They contain just as much sugar, often in the same amounts as cola. Even juices and sweetened teas can have similar sugar loads. The key factor is the total sugar content, not the specific flavor or brand.

How Quickly Can Soda Affect Your Skin?

There is no fixed timeline. A pimple forms over days to weeks, not hours. The process involves oil production, cell turnover, and inflammation, all of which take time. Drinking a soda today is unlikely to cause a visible pimple tomorrow.

Consistent daily consumption matters more than a single drink. If you drink soda regularly, your insulin levels are frequently elevated. This creates a sustained environment that promotes oil production and clogged pores. Reducing intake over several weeks may lead to noticeable improvements in skin, though individual results vary.

Some people are more sensitive to dietary triggers than others. If your skin is already prone to acne, the effect of soda may be more pronounced. If you rarely break out, you may not notice any difference.

What Can You Do Instead?

Reducing soda intake is a reasonable step if you struggle with acne. This does not require eliminating it completely, but cutting back can help. Replacing soda with water is the simplest change. Water has no sugar, no calories, and does not affect insulin levels.

If you crave carbonation, sparkling water is a good alternative. Unsweetened tea or coffee are also low-sugar options. If you want sweetness, consider fruit-infused water or a small amount of natural juice mixed with sparkling water.

Diet soda can serve as a transitional option if you are trying to reduce sugar. It removes the insulin spike, though the long-term effects on skin remain uncertain. The safest approach for skin health is to minimize all sweetened beverages, whether they contain sugar or artificial sweeteners.

Remember that diet is only one piece of the acne puzzle. A consistent skincare routine, adequate sleep, stress management, and, when needed, medical treatments are all important. If acne is severe or persistent, a dermatologist can provide treatments that are proven to work, such as topical retinoids, benzoyl peroxide, or prescription medications.

Is There Any Benefit to Quitting Soda Entirely?

Quitting soda entirely can improve more than just your skin. Reducing added sugar intake is associated with better overall metabolic health, including lower risk of type 2 diabetes and heart disease. These benefits are well established and independent of any effect on acne.

For skin specifically, eliminating regular soda removes a consistent source of high-glycemic sugar. This can help stabilize insulin levels, which may reduce oil production and inflammation. Some people see clearer skin within a few weeks of cutting out sugary drinks.

No clinical guidelines currently specify an exact amount of soda that is safe for acne-prone skin. The general direction of the evidence is clear: less added sugar is better for your skin and your health. You do not need to be perfect, but consistent reduction is a practical and evidence-based goal.
