Large, visible pores are a common skin concern, and while genetics play a role, your daily diet—especially what you drink—can also influence their appearance. Dermatologists point to two particular beverages that may make pores look larger by triggering inflammation, dehydration, or excess oil production. Understanding how these drinks affect your skin can help you make informed choices for a smoother, more refined complexion.
What makes pores look bigger?
Pores don't have muscles to open and close, but they can appear larger when they become clogged with oil, dead skin cells, or debris. When the surrounding skin loses elasticity or becomes dehydrated, pores can also look more pronounced. Certain drinks can worsen these factors, leading to a less even skin texture.
The first culprit: sugary sodas and sweetened beverages
Dermatologists often point to sugary drinks as a primary suspect for enlarged pores. High-glycemic beverages like soda, sweetened iced tea, and fruit punches cause rapid spikes in blood sugar and insulin. This hormonal surge can stimulate the sebaceous glands to produce more sebum (oil). Excess oil then mixes with dead skin cells, stretching the pores and making them more visible.
A 2021 review in the journal Clinical and Experimental Dermatology found that high-glycemic diets are linked to increased sebum production and acne severity—both of which contribute to the appearance of larger pores.
For best skin health, try swapping soda for sparkling water with a splash of lemon or cucumber. If you crave sweetness, opt for whole fruits instead of fruit juices, which lack fiber and cause a similar sugar spike.
The second culprit: dairy milk (especially skim milk)
While not a drink for everyone, cow's milk is a common beverage that dermatologists associate with pore congestion. Research suggests that dairy, particularly skim milk, can influence insulin-like growth factor 1 (IGF-1) levels, which may increase sebum production. More oil means a greater chance of clogged pores and a stretched appearance.
One study in the Journal of the American Academy of Dermatology noted that participants who consumed more skim milk had higher rates of acne, which often coincides with enlarged pores. For those sensitive to dairy, switching to unsweetened almond milk, oat milk, or coconut milk may help reduce pore visibility over time.
How alcohol and caffeine fit in
While not the main focus, dermatologists note that alcohol and excessive caffeine can dehydrate the skin, causing it to lose plumpness. When skin dehydrates, the tissue around pores can shrink, making the pore openings appear larger by contrast. Moderation is key: for every alcoholic or caffeinated drink, pair it with a glass of water to maintain hydration and skin elasticity.
Lifestyle tips to minimize pore appearance
Beyond cutting back on sugary drinks and dairy, a few simple habits can help keep pores looking their smallest:
- Stay hydrated: Drink plenty of water throughout the day to keep skin plump and supple.
- Use non-comedogenic products: Look for moisturizers and sunscreens labeled as non-comedogenic to avoid clogging pores.
- Exfoliate gently: A mild chemical exfoliant with salicylic acid or niacinamide can help clear debris from pores.
- Protect from sun damage: Daily sunscreen use prevents collagen breakdown, which keeps skin firm and pores less noticeable.
When to see a dermatologist
If dietary changes don't improve pore size, a board-certified dermatologist can offer treatments like topical retinoids, chemical peels, or laser therapies to refine skin texture. Remember, pores are normal and necessary for skin health—the goal is minimizing their appearance, not eliminating them entirely.
