Does Drinking Black Tea Help Acne? | Evidence Check

Research suggests drinking black tea may help with acne due to its anti-inflammatory and antimicrobial polyphenols.

You’ve probably seen the glowing headlines: “Drink this tea to clear your skin.” Green tea gets most of the credit for acne, but black tea sits right next to it on the shelf, and both come from the same plant. The difference is how they’re processed — black tea is fully oxidized, which changes its polyphenol profile. That difference matters for your skin.

So does drinking black tea help acne? The honest answer: it may support acne management through several pathways, but the science is stronger for green tea, and the evidence specifically for black tea is mostly indirect. This article walks through what the research actually says, where the gaps are, and how to decide if black tea is worth adding to your routine.

How Black Tea Could Help Acne

Acne vulgaris develops when excess sebum, dead skin cells, and Cutibacterium acnes bacteria clog pores, triggering inflammation. Black tea contains polyphenols — including theaflavins and thearubigins — that act on several of those steps.

According to a comprehensive review from the NIH, tea polyphenols can reduce sebum production and act as antimicrobial, anti-inflammatory, and antioxidant agents — all mechanisms that may help manage acne. The review notes that these effects have been demonstrated with tea polyphenols broadly, though many of the individual studies use green tea extracts.

Black tea also contains tannins, which some beauty sources suggest have antibacterial properties that may help calm minor skin irritations and redness. These claims come largely from commercial beauty sites rather than clinical trials, but the mechanism is biologically plausible.

Why The Green Tea Bias Exists

Most people assume “tea is good for skin” and reach for whatever bag is in the cupboard. But the research is lopsided — green tea’s EGCG (epigallocatechin gallate) is one of the most studied compounds in dermatology, while black tea’s unique polyphenols have received far less attention in skincare trials.

• Polyphenol profile differences: Black tea’s fermentation converts catechins into theaflavins and thearubigins. Both classes show antioxidant and anti-inflammatory activity, but the clinical acne data is mostly on catechins from green tea.
• Limited human studies: Most peer-reviewed work on tea and acne uses topical extracts or oral supplements of green tea. Drinking black tea as a beverage hasn’t been tested head-to-head in acne-specific trials.
• Dose uncertainty: Even if black tea polyphenols reach the skin through drinking, the concentration in a cup is much lower than in a concentrated extract or topical application used in studies.
• Individual variability: Gut absorption and metabolism of tea polyphenols vary by person, which means one person’s cup of black tea may not deliver the same skin benefits as another’s.

None of this means black tea is useless for acne — just that the evidence is weaker than the green tea hype would suggest. If you enjoy black tea, there’s no harm in drinking it, but expecting it to act like a topical treatment may set you up for disappointment.

What The Research Says About Black Tea And Acne

The strongest supporting data comes from a 2017 review published in PMC that systematically examined tea polyphenols and skin health. The review concludes that tea polyphenols — including those found in black tea — can reduce sebum production and inhibit acne-related bacteria, as detailed in the tea polyphenols reduce sebum paper. But the caveat is important: the review defines “tea polyphenols” broadly, and the studies cited often use green tea extract at doses far higher than what you’d get from a cup.

Separate research from MDPI’s Antioxidants journal confirms that tea polyphenols act through multiple acne-relevant pathways — antioxidant, antimicrobial, anti-inflammatory — and that these effects are seen with both green and black tea varieties. Again, direct beverage trials are thin.

On the practical side, several beauty blogs and commercial tea sites recommend drinking black tea for acne based on its tannin content and anti-inflammatory properties. While these sources are Tier 2 (lacking clinical rigor), they reflect a widespread belief that black tea helps calm breakouts. The bottom line: the mechanism supports the idea, but the hard proof for drinking black tea specifically isn’t there yet.

This table shows the polyphenol families present in different teas and what the current evidence suggests about their role in acne. Black tea’s unique compounds are active in the lab, but human data lags behind.

How To Use Black Tea For Acne Without Overhyping It

If you want to try black tea for your skin, you have two main options: drinking it or applying it topically. Neither is a replacement for dermatologist-recommended treatments, but both are generally low-risk.

1. Drink 1–2 cups per day: Brew black tea normally and drink it unsweetened. Sugar and milk may trigger breakouts in some people, so avoid additions. Consistency over weeks may allow polyphenols to accumulate in skin tissue.
2. Try a cooled tea compress: Steep a strong cup, let it cool completely, then apply the tea bag or soak a cotton pad and press onto clean skin for 5–10 minutes. The direct contact delivers polyphenols topically.
3. Watch for irritation: Black tea is generally safe for most skin types, but if you notice redness or dryness after topical use, discontinue. Caffeine can be mildly irritating for very sensitive skin.
4. Don’t skip proven treatments: Drinking black tea is a complementary habit, not a standalone solution. For moderate to severe acne, see a dermatologist for prescription options like retinoids or benzoyl peroxide.

What To Know Before Adding Black Tea To Your Routine

The anti-inflammatory and antioxidant potential of black tea is real, but the evidence for drinking it as an acne treatment remains mostly theoretical. A 2021 article from Bebeautiful notes that black tea’s antibacterial and antifungal properties — attributed to its tannins — may help treat minor skin irritations, acne, and redness. That aligns with the black tea antibacterial acne claim, but again, it’s based on lab mechanisms rather than human trials.

One overlooked angle is the gut-skin connection. Tea polyphenols may improve gut microbial balance and strengthen the epithelial barrier, which in turn could reduce systemic inflammation that contributes to acne. This pathway is supported by a 2022 review in Food Science and Human Wellness, but the research is early and not specific to black tea.

Bottom line: black tea is a low-risk addition to a healthy diet, and its polyphenols may modestly support clearer skin. Just don’t expect it to work like a prescription — treat it as a supportive habit, not a cure.

The Bottom Line

Drinking black tea may offer some benefit for acne through its antioxidant and anti-inflammatory polyphenols, but the evidence is far from conclusive. Most of the strong research has been done on green tea extracts, and no major trial has tested black tea beverages against acne directly. If you already enjoy black tea, keep drinking it — just don’t overhaul your skincare routine around it.

If acne is persistent or severe, a dermatologist or primary care provider can help you create a targeted plan. Your specific skin type, triggers, and any other treatments you’re using will determine whether black tea is a helpful addition or just a pleasant drink.
