A 2025 National Coffee Association report found that 66% of American adults drank coffee daily, making it one of our most ingrained morning rituals. So if you are struggling with breakouts, you may reluctantly wonder: is your morning latte sabotaging your skin?

Quick Answer: Does Coffee Cause Acne?

Coffee itself is not a proven cause of acne, but milk and added sugar may contribute to breakouts in some people. Caffeine can also affect sleep and stress, which may matter for acne-prone skin. Start with what is in your cup, then consider how much you drink and when.

The answer supported by current research is that coffee has not been established as a direct acne trigger. Research on diet and acne points more strongly to high-glycemic diets and, less consistently, dairy; that does not prove that every latte causes a breakout.

What Does the Research Say About Coffee and Acne?

Surprisingly, there is very little research directly examining whether coffee causes acne. Most of the claims you see online are extrapolated from studies on caffeine's effects on cortisol, or from research on dairy and sugar — ingredients that happen to be common coffee additions but have nothing to do with coffee itself.

The Limited Direct Evidence

Research directly linking coffee to acne is limited. The Nurses' Health Study analysis of diet and teenage acne examined dairy intake rather than coffee specifically. For more on that distinction, see whether dairy causes acne.

A 2022 systematic review in JAAD International found support for a modest acne-promoting effect of high-glycemic diets; evidence for dairy was mixed and varied by population. It does not establish coffee itself as an acne cause.

What to expect: The research on coffee and acne is limited, and what exists does not support coffee as a direct cause of breakouts. However, the indirect effects of caffeine — along with the dairy and sugar many people add to their coffee — are worth understanding. The dose and the preparation matter far more than the bean itself.

How Coffee Might Affect Your Acne

Even if coffee is not a direct acne trigger, there are several indirect pathways through which your coffee habit could be contributing to breakouts. These are the mechanisms that actually matter.

Dairy and Sugar: The Real Culprits in Your Coffee

If there is one takeaway from this article, let it be this: what you add to your coffee is almost certainly more relevant to your acne than the coffee itself.

The connection between dairy and acne is well-documented. Multiple large studies and meta-analyses have found that dairy consumption — particularly milk — is associated with an increased risk of acne. Milk contains insulin-like growth factor 1 (IGF-1), hormones, and androgen precursors that stimulate oil production, promote inflammation, and activate acne-promoting pathways in the skin.

A 2018 meta-analysis published in Nutrients pooling data from nearly 80,000 participants found that any dairy consumption was associated with higher odds of acne, with skim milk showing a higher association than whole milk. When you add a splash of skim milk or a pour of cream to every cup of coffee — potentially multiple times per day — that dairy intake adds up quickly.

Sugar is the other major concern. The added sugar in flavored coffee drinks — vanilla lattes, caramel macchiatos, mocha frappuccinos — drives significant insulin spikes. A landmark 2007 study in the American Journal of Clinical Nutrition demonstrated that a low-glycemic diet (one that minimizes blood sugar spikes) led to significant improvement in acne compared to a standard diet. High-glycemic foods and sugary drinks do the opposite: they raise insulin and IGF-1 levels, which directly fuel the biological processes behind acne.

Consider what is actually in a typical coffee-shop drink:

Drink Added Sugar Dairy Content Acne Risk Factors
Black coffee 0 g None No added dairy or sugar; caffeine may affect sleep
Coffee with cream and sugar 8-12 g 1-2 oz cream Contains dairy and added sugar
Latte (skim milk) 0 g (unflavored) 8-12 oz skim milk Milk intake is associated with acne in some studies
Vanilla latte 25-35 g 8-12 oz milk Contains milk and added sugar
Caramel frappuccino 45-65 g Milk + whipped cream Often contains milk, cream, and added sugar; recipes vary
Coffee with oat milk (unsweetened) 0-1 g None No dairy; check the label for sugar content

The difference between a black coffee and a caramel frappuccino is enormous when it comes to acne risk. One is essentially calorie-free with some antioxidants. The other is a delivery system for dairy, sugar, and whey — all of which have documented associations with breakouts.

Caffeine and Cortisol: The Stress Hormone Connection

This is the most commonly cited reason why coffee might worsen acne, and there is some truth to it — though the effect is often overstated.

Caffeine can temporarily stimulate cortisol release. A controlled study in Psychosomatic Medicine found that the response varied with recent caffeine intake and time of day. This explains a possible indirect pathway; it does not show that coffee causes acne.

Stress and acne are associated, but the relationship involves several pathways. A study of psychological stress and acne found greater acne severity with higher stress levels; it did not establish that a caffeine-induced cortisol rise causes breakouts.

Habitual caffeine use can blunt some cortisol responses, but tolerance is incomplete. Coffee also contains antioxidant compounds, as discussed in a review of its benefits and risks; that does not establish drinking it as an acne treatment.

The cortisol concern is most relevant if you are drinking large amounts of coffee (four or more cups per day), consuming it late in the day when it interferes with sleep, or combining caffeine with other stressors that are already elevating your cortisol.

Caffeine and Sleep Disruption

The third way coffee can indirectly affect your acne is through its impact on sleep. Caffeine has a half-life of roughly five to six hours, meaning that a cup of coffee at 3 PM still has half its caffeine active in your system at 8 or 9 PM. This can reduce total sleep time, decrease sleep quality, and delay sleep onset — even if you feel like you fall asleep fine.

Caffeine can reduce sleep quality, and sleep loss can affect stress hormones. A sleep-loss study found higher cortisol the following evening. These findings support paying attention to sleep, but do not prove that late coffee causes acne.

If your afternoon or evening coffee is cutting into your sleep quality, it could be contributing to breakouts through this indirect cortisol pathway — even if the caffeine itself is not directly causing acne.

Red flag: If you are drinking coffee late in the day, having trouble sleeping, and noticing your acne getting worse, the sleep disruption may be a bigger factor than the caffeine itself. Try cutting off caffeine by early afternoon and see if your sleep — and your skin — improve over the course of a few weeks.

Does Caffeine Cause Acne? Black Coffee vs. Lattes

Not all coffee drinks are created equal when it comes to acne. The distinction between black coffee and a dairy-heavy coffee drink is probably the most important thing to understand about this topic.

Black Coffee: Likely Fine for Most People

Plain black coffee — no milk, no cream, no sugar — has very little going against it from an acne perspective. It contains zero calories, no dairy, no added sugar, and a meaningful dose of antioxidants. The only potential concern is the cortisol-raising effect of caffeine, and for habitual drinkers consuming moderate amounts (one to three cups per day), that effect is blunted by tolerance.

Some dermatologists even note that the anti-inflammatory polyphenols in coffee could theoretically offer a small protective benefit for skin health, though this has not been studied specifically in the context of acne prevention.

Lattes and Milk-Based Drinks: Where the Risk Increases

A latte, cappuccino, or flat white is fundamentally a dairy delivery vehicle. A standard 16-ounce latte contains roughly 12 ounces of steamed milk, which provides a significant dose of the IGF-1, hormones, and insulin-spiking compounds that research has linked to acne. If you drink a latte every day, you are consuming the equivalent of about 10.5 cups of milk per week from your coffee alone.

A 2018 meta-analysis reported higher odds of acne with milk consumption, while noting limitations in the observational evidence. It cannot predict whether a particular person will break out after a latte.

Sweetened Coffee Drinks: The Biggest Concern

Flavored coffee drinks from cafes combine the worst of both worlds for acne-prone skin: high amounts of dairy and high amounts of sugar. A grande vanilla latte from a typical coffee chain contains around 25 to 35 grams of sugar, and more elaborate drinks like frappuccinos can exceed 60 grams. That is the equivalent of more than 15 teaspoons of sugar in a single drink.

These sugar levels cause substantial insulin spikes, which in turn elevate IGF-1 and drive the same sebum-producing, pore-clogging processes that make acne worse. If you have a daily sweetened coffee habit and persistent acne, the sugar in your drink is a factor worth taking seriously.

What to expect: Switching from a sweetened, milk-based coffee drink to black coffee or coffee with unsweetened non-dairy milk is one of the simplest dietary changes you can make for your skin. If dairy and sugar in your coffee are contributing to your breakouts, you may start to notice improvement within four to six weeks of making the switch — though results will depend on the other factors involved in your acne.

Practical Tips for Coffee Lovers with Acne

The good news is that you almost certainly do not need to give up coffee. A few adjustments to how you drink it can minimize any potential impact on your skin.

1. Swap Dairy Milk for a Non-Dairy Alternative

If you prefer your coffee with something in it, switch from cow's milk to an unsweetened non-dairy option like oat milk, almond milk, or coconut milk. These do not contain the IGF-1, hormones, or whey proteins that connect dairy to acne. Unsweetened is the key word here — flavored or sweetened plant milks can contain enough sugar to cause their own insulin issues.

2. Cut the Sugar and Flavored Syrups

If you are used to ordering sweetened drinks, try gradually reducing the amount of sugar or syrup. Many coffee shops will make drinks with half the standard syrup, and you can reduce from there. Over time, your palate adjusts, and the natural flavor of good coffee can become satisfying on its own.

3. Keep Caffeine Intake Moderate

Stick to roughly 400 mg of caffeine per day or less — the amount the FDA considers safe for most adults, which translates to about three to four standard cups of brewed coffee. This level keeps the cortisol-elevating effects manageable, especially if you are a habitual drinker whose body has built tolerance.

4. Stop Caffeine by Early Afternoon

Given caffeine's long half-life, avoid coffee after about 1 to 2 PM. This gives your body enough time to clear most of the caffeine before bedtime, protecting your sleep quality and preventing the cortisol-elevating effects of poor rest. Better sleep is one of the most underrated tools for managing acne.

5. Stay Hydrated

Caffeine is a mild diuretic, meaning it can increase fluid loss. Dehydrated skin can compensate by producing more oil, which contributes to clogged pores. Drink water alongside your coffee to stay well-hydrated throughout the day.

6. Pay Attention to Patterns

If you suspect your coffee habit is affecting your skin, try tracking what you drink and how your skin responds over several weeks. Keep a simple log of your coffee type, additions (milk, sugar), timing, and any breakouts you notice. Patterns often become visible within four to six weeks. This information is also valuable to share with a dermatologist if you decide to seek professional advice.

Acne-Friendly Coffee Checklist

  • Choose black coffee or use unsweetened non-dairy milk
  • Skip the added sugar, syrups, and whipped cream
  • Limit to 3-4 cups per day (roughly 400 mg caffeine)
  • No coffee after early afternoon to protect sleep
  • Drink water alongside your coffee
  • Track your intake and breakouts for patterns

When Diet Changes Are Not Enough

Here is the reality: adjusting your coffee order might help around the edges, but for most people with persistent acne, it is not going to be the whole solution. Acne is a complex condition driven by genetics, hormones, bacteria, and inflammation. Diet plays a role — sometimes a meaningful one — but it is usually one piece of a much larger puzzle.

If you have been making dietary changes, keeping up with a good skincare routine, and still breaking out, it is time to see a dermatologist. Prescription treatments target acne at the root level in ways that lifestyle adjustments cannot.

Depending on your acne type and severity, a dermatologist may recommend:

  • Topical retinoids (like tretinoin) to normalize skin cell turnover and prevent clogged pores
  • Topical or oral antibiotics (like doxycycline) to reduce acne-causing bacteria and inflammation
  • Spironolactone for hormonally driven acne
  • Isotretinoin (Accutane) for persistent acne that has not responded to other treatments

What to expect: Diet modifications like changing your coffee order work best alongside — not instead of — evidence-based medical treatment. Your dermatologist can help you understand how factors like caffeine, dairy, and sugar fit into your overall acne picture and build a plan that addresses everything together.

The Bottom Line

The question "does coffee cause acne?" has a straightforward answer once you look at the evidence: coffee itself is not a proven cause of breakouts, and you almost certainly do not need to give it up. The real culprits are the dairy, sugar, and flavored syrups that turn a simple cup of coffee into something your skin may not tolerate — plus the indirect effects of excessive caffeine on cortisol and sleep quality.

If you love coffee and have acne, start with the easy wins: switch to black coffee or use unsweetened non-dairy milk, skip the sugar, keep it to a reasonable amount, and do not drink it too late in the day. These are simple changes that can meaningfully reduce any contribution your coffee habit is making to your breakouts.

But if your acne persists despite dietary adjustments, do not spend months or years trying to figure it out through diet changes alone. A dermatologist can evaluate your skin, identify the specific factors driving your acne, and prescribe targeted treatments that address the root causes. You deserve clear skin — and you deserve your coffee, too.
