How to Support Your Skin in the Luteal Phase Through Diet

If your breakouts appear in the week before your period, you are likely experiencing luteal phase acne.

The luteal phase is the second half of your menstrual cycle, typically days 15 to 28. During this time, hormonal shifts can increase oil production, inflammation and skin sensitivity. While skincare plays a role, diet can also support your skin during this phase.

Before we discuss how to approach luteal phase nutrition for hormonal acne, lets first summarise why skin changes in the luteal phase...

In the luteal phase:

• Oestrogen begins to decline
• Progesterone rises
• Androgen influence becomes relatively stronger
• Inflammatory signalling may increase

This shift can lead to:

• Oilier skin
• Congestion around the chin and jawline
• Deeper, more inflamed spots

 

Supporting hormonal balance and inflammation through diet may help reduce the intensity of premenstrual breakouts.

 

1. Prioritise fibre for oestrogen metabolism

Fibre plays a crucial role in healthy hormone metabolism, adequate fibre intake supports:

• Regular bowel movements
• Oestrogen clearance
• A healthy gut microbiome

 

Foods to include:

• Flaxseeds
• Chia seeds
• Oats
• Lentils
• Chickpeas
• Leafy greens
• Cruciferous vegetables such as broccoli and cabbage

Supporting digestion during the luteal phase may help maintain hormonal balance.

 

2. Support stable blood sugar

Blood sugar fluctuations can influence insulin levels, which in turn affect androgen activity. High insulin can stimulate androgen production, potentially increasing oil output.

To keep blood sugar stable:

• Prioritise protein at every meal
• Pair carbohydrates with healthy fats
• Choose whole grains over refined sugars
• Avoid large spikes from ultra-processed foods

Steadier blood sugar can mean steadier skin.

 

3. Include zinc-rich foods

Zinc plays a role in immune regulation and oil gland function. Zinc-rich foods include:

• Pumpkin seeds
• Oysters
• Eggs
• Beans
• Cashews

Supporting zinc intake during the luteal phase may help maintain balanced inflammatory responses in the skin.

4. Focus on anti-inflammatory fats

Hormonal acne is not only about oil production. It is also inflammatory. Omega-3 fatty acids may help support inflammatory balance.

Foods to include:

• Oily fish such as salmon and sardines
• Walnuts
• Chia seeds
• Flaxseed oil

Reducing processed seed oils and excessive refined sugars may also support calmer skin.

5. Do not undereat

The luteal phase often brings increased hunger, which is normal!

Severely restricting calories can increase stress hormones, which may influence inflammatory pathways and androgen activity. Instead of restricting, focus on:

• Balanced meals
• Adequate protein
• Complex carbohydrates
• Sufficient healthy fats

 

6. Stay hydrated

Hydration supports:

• Skin barrier function
• Detoxification pathways
• Digestive regularity

While water alone will not prevent breakouts, adequate hydration supports overall skin resilience during this more reactive phase.

A luteal phase skin strategy

During the week before your period, focus on:

• Fibre for hormone clearance
• Stable blood sugar
• Zinc and micronutrient intake
• Anti-inflammatory fats
• Gentle, consistent nourishment

Diet alone may not eliminate hormonal acne, but it can support the internal environment that influences how intensely your skin reacts each month.
