Acne is rarely caused by just one thing. While skincare is incredibly important, factors like nutrition, stress, hormones, and lifestyle habits can all play a big role in the health of your skin.
That’s why I asked Lucy Greene, our Lead Master Esthetician and Acne Specialist, to share some of the insights she discusses with her acne clients every day. From common food triggers to supportive swaps, this blog is full of practical tips that may help you better understand the connection between your diet and your skin.
Take it away, Lucy…
What I Actually Talk About With My Acne Clients
If you struggle with acne, I want you to know something right away:
You do not need a perfect diet to have clear skin.
One of the biggest mistakes I see people make is becoming overwhelmed trying to “eat perfectly” for their skin. Then they end up stressed, frustrated, and honestly miserable.
That is not the goal.
The goal is learning your triggers, supporting your body, and making realistic changes you can actually stick with long term.
Because acne is not just about skincare. It is often connected to inflammation, hormones, digestion, blood sugar swings, stress, and lifestyle habits too.
When I work with acne clients, food is one of the areas we look at together.
One of My Favorite Starting Points: A 3-Day Food Journal
Instead of telling clients to cut out everything immediately, I usually have them send me a simple 3-day food journal. This helps us look for patterns.
Are they consuming dairy multiple times a day?
Whey protein every morning?
Coffee on an empty stomach?
Energy drinks?
A lot of processed snacks or sugar late at night?
Sometimes the trigger becomes very obvious once we step back and actually look at the habits.
From there, we can decide if it is worth reducing or eliminating certain foods temporarily to see how the skin responds and, honestly, how they feel overall. Acne takes 30-90 days to form so when modifying foods, it’s important to give it time to see a positive impact on your skin.
Moderation Is Key
I am not a fan of extreme restriction.
Most clients do much better when they focus on moderation and gradual change instead of trying to overhaul their entire life overnight.
If you are feeling overwhelmed, start simple.
For example:
- If you drink coffee on an empty stomach every morning, try eating something first.
- If you drink 3 coffees a day, try slowly cutting back to 2, then 1.
- Maybe switch to half-caf for a while.
- Maybe eventually try decaf or green tea.
Caffeine is honestly a big trigger for a lot of my acne clients, especially when stress and hormones are already involved. Little changes add up.
Foods That Tend to Support Clear Skin
These foods tend to support the body and calm inflammation, which can help acne-prone skin function better.
Anti-Inflammatory Foods
- Turmeric
- Ginger
- Matcha and green tea
- Ceylon cinnamon
- Apple cider vinegar
These can help calm inflammation internally, which often reflects in the skin.
Omega-3 Rich Foods
Most people are not getting enough omega-3s.
Some of my favorite skin-supportive options:
- Salmon
- Sardines
- Walnuts
- Hemp seeds
- Mackerel
Omega-3s are amazing for supporting the skin barrier and calming inflamed acne.
Antioxidant-Rich Foods
- Blueberries
- Spinach
- Kale
- Leafy greens
- Brazil nuts
These help protect the skin and support healing.
Better Sweet Craving Swaps
A little tip I give clients all the time:
If you tend to crave candy or ice cream late at night, try fruit first — but pair it with something that helps stabilize blood sugar.
Examples:
- Apple + almond butter
- Berries + a handful of walnuts
- Banana + peanut butter
- Dates + mixed nuts
Pairing natural carbohydrates with protein or healthy fats can help slow blood sugar spikes and keep you fuller longer, which may help reduce inflammation and cravings.
You do not have to be perfect. Sometimes small swaps done consistently can make a huge difference in the skin.
Foods That Commonly Trigger Acne
Not every food affects every person the same way, but these are some of the biggest acne aggravators I see repeatedly.
Dairy
Dairy is one of the most common triggers for acne-prone skin.
Especially:
- Milk
- Cheese
- Ice cream
- Yogurt
This is because dairy can stimulate hormones and oil production in the skin.
Whey Protein
This one is huge.
I cannot tell you how many clients improve after removing whey protein and switching to a vegan option.
Whey is strongly associated with:
- Congested pores
- Increased oil production
- Inflamed breakouts
I usually recommend switching to a plant-based protein powder instead.
Look for:
- Pea protein
- Hemp protein
- Brown rice protein
These tend to be much gentler on acne-prone skin.
Coffee and Caffeine
This one surprises people sometimes.
Coffee itself is not “bad,” but caffeine can absolutely worsen acne for some people, especially when combined with:
- Stress
- Poor sleep
- Hormone fluctuations
- Drinking it on an empty stomach
Sometimes even just reducing caffeine makes a noticeable difference.
A lot of clients do better swapping some coffee for:
- Matcha
- Green tea
- Lower caffeine options
Highly Processed and Sugary Foods
- Candy
- Pastries
- Fried foods
- Fast food
- Sugary drinks
- Processed snacks
These can contribute to inflammation and blood sugar spikes that often show up in the skin.
Iodides (An Overlooked Trigger)
This is one a lot of people have never heard about.
Excess iodides can irritate the pore and contribute to breakouts.
Some common sources:
- Iodized salt
- Seaweed
- Kelp
- Certain supplements
- Shellfish
Again, this is not about fear or perfection. It is about awareness.
If You Have Acne AND Stomach Issues, Look Deeper
This is another pattern I see often.
If someone struggles with acne alongside:
- Bloating
- Constipation
- Digestive discomfort
- Food sensitivities
- Irregular bowel movements
…it is worth looking deeper into gut health.
This is where working with our wellness team for things like stool testing can sometimes be really helpful.
Your skin and gut are very connected.
You do not need to become obsessive about food to improve your skin. Most of the time, it is about looking for patterns. reducing common aggravators. supporting your body consistently, and making realistic swaps that you can actually maintain.
Your skin is always communicating with you. Sometimes we just need to slow down enough to listen to what it has been trying to say.
Acne can be frustrating, but you don’t have to navigate it alone. I offer both virtual acne guidance and see patients in-person at Racquel Aesthetics & Wellness. You can contact me through my Instagram page @lucyhatesacne to create a plan together for your acne!
