You've got a solid skincare routine. You double-cleanse, you exfoliate, you reach for the salicylic acid. But those tiny dark plugs on your nose and chin just won't budge. Before you blame your moisturizer or your pillowcase, take a look at what's in your glass. Some everyday drinks can throw off your skin's oil balance and create the perfect environment for blackheads to form.
Here's the problem: glands just beneath the skin's surface churn out sebum to protect and lubricate. When that sebum mixes with dead skin cells and gets trapped inside a pore, it oxidizes and turns dark — that's a blackhead. Refined carbohydrates (yes, including liquid ones) can spike insulin, which kick-starts more oil production. Dairy and certain plant milks can also signal your skin to overproduce sebum. Below are three common beverages that might be making your blackheads worse, along with smarter swaps for a clearer complexion.
Sugary coffee and blended coffee drinks
Your morning latte with caramel drizzle or that afternoon frozen coffee treat may be a top culprit. The issue isn't the coffee itself — it's the sugar. A single grande caramel Frappuccino packs around 55 grams of sugar (that's more than 13 teaspoons). All that sugar spikes glucose and insulin, which in turn ramps up the skin's production of sebum and inflammation. The result is more clogged pores and, with time, more blackheads.
Better option: Stick with black coffee or espresso. It's virtually sugar-free and still gives you the caffeine boost. If that's too bitter, a splash of unsweetened oat or almond milk won't spike insulin. Skip the syrup and try a sprinkle of cinnamon for flavor instead.
A single fancy coffee drink can contain more sugar than a chocolate bar — and your pores feel the effect.
Whey protein shakes and bars
If you're using whey-based protein powders for muscle recovery or meal replacement, you might be feeding your blackheads. Whey is a dairy derivative, and studies suggest dairy can boost insulin-like growth factor 1 (IGF-1), which increases sebum production. Some people also find that whey itself triggers acne breakouts, including comedonal acne (blackheads and whiteheads). This doesn't mean all protein is bad — just the whey kind.
Better option: Try plant-based protein powders made from pea, hemp, or brown rice. They contain amino acids for muscle repair without the dairy-related hormone response. Unsweetened varieties will also avoid the sugar trap. Read the ingredients list — many powders labeled "natural" still contain artificial sweeteners or added sugars that can affect your blood sugar.
Commercial almond and oat milk (the flavored kinds)
Wait — isn't almond milk supposed to be healthy? The unsweetened, plain versions are fine. But the flavored options (vanilla almond milk, barista blends, chocolate oat milk) are a different story. Many brands add sugar, sunflower lecithin, and stabilizers that can have a surprisingly high glycemic effect. A cup of chocolate oat milk can contain 23 grams of added sugar. The stabilizers and gums in some plant milks may also trigger inflammatory responses in sensitive skin, contributing to congestion.
Better option: Choose unsweetened, original-forat almonds or oat milk. Check the label: aim for fewer than 2 grams of sugar per serving. Homemade almond milk (soaked almonds blended with water and strained) is even better — no additives, no sugar.
What to sip for clearer pores
The best drinks for your skin keep blood sugar stable and provide extra hydration or beneficial compounds. Here are three smart alternatives that may help reduce blackhead formation over time:
- Green tea. It's rich in catechins (antioxidants) that help reduce inflammation. Some research has also found that applying green tea extract topically can reduce sebum production. Sipping it daily might provide a milder systemic benefit.
- Water (plain or infused). Hydration helps keep skin cells plump, so dead cells shed normally. Add slices of lemon, cucumber, or mint for flavor — none of these add sugar.
- Spearmint tea. For adults with hormonal acne (often along the jawline and chin), spearmint tea twice a day may help lower free testosterone in the blood, which can reduce oil production. It's not a quick fix but can support clearer pores over a few weeks.
Switching out even one or two of your daily drinks can make a noticeable difference in your skin's oiliness and the number of blackheads. If you still see stubborn blackheads after adjusting your drinks, consider adding a gentle salicylic acid toner and non-comedogenic moisturizer to your skincare routine. Skin changes take time — give it three to four weeks before judging the effect.
