Does Diet Affect Acne?

Acne is a complex inflammatory skin condition influenced by hormones, genetics, oil production, bacteria, and inflammation. While diet is not usually the sole cause of acne, research suggests that certain foods may contribute to breakouts in some people.

For many patients, improving acne involves a combination of:

consistent skincare
targeted active ingredients
lifestyle management
and in some cases, dietary adjustments

Understanding how diet may affect the skin can help support a more balanced approach to acne management.

Understanding Acne: Causes, Symptoms, and Skincare That Helps

This article explains the different causes of acne, common triggers, and the ingredients most commonly recommended for acne-prone skin.

Foods That May Trigger Acne

High Glycaemic Foods

Foods that rapidly increase blood sugar levels may contribute to acne by increasing insulin and inflammation.

Examples include:

sugary snacks
white bread
pastries
fizzy drinks
highly processed foods

High insulin levels can increase oil production and stimulate hormonal pathways linked to acne.

Dairy Products

Some studies suggest that dairy, particularly skimmed milk, may worsen acne in certain individuals. This may be linked to hormones and growth factors naturally present in milk.

Not everyone is affected by dairy, but for some acne-prone patients, reducing intake may improve breakouts.

Highly Processed Diets

Diets low in antioxidants and high in processed foods may contribute to inflammation within the body, which can also influence inflammatory acne.

A balanced diet rich in vegetables, healthy fats, protein, and fibre may help support overall skin health.

While dietary factors may contribute to acne in some individuals, they are rarely the only cause. Successful acne management usually involves a combination of skincare, lifestyle adjustments, and targeted treatment strategies.

Can Supplements Help Acne?

While supplements are not a replacement for medical acne treatment, some ingredients may help support skin health from within.

Collagen & Skin Support

Maintaining skin barrier health and hydration is important when using acne treatments that may dry or sensitise the skin.

The Importance of Skincare Alongside Diet

Even when diet plays a role, skincare remains one of the most important aspects of acne management.

Ingredients that can help include:

salicylic acid
retinoids
niacinamide
azelaic acid
benzoyl peroxide

A tailored skincare routine is often essential for controlling breakouts and reducing post-acne marks.

One of the biggest misconceptions among acne sufferers is that moisturiser should be avoided. In reality, maintaining a healthy skin barrier is often essential for managing breakouts successfully.

When to Seek Professional Advice

If acne is persistent, painful, hormonal, or leaving marks and scarring, professional treatment may be beneficial.

A personalised consultation can help determine:

whether hormones or lifestyle are contributing
which skincare ingredients are most suitable
whether prescription treatments may help
and how to build an effective long-term acne routine

If you've already tried changing your diet, using acne skincare, or following online advice without success, a personalised consultation can help identify whether hormones, inflammation, skincare, lifestyle factors, or other triggers may be contributing to your breakouts.

We can also advise on prescription treatments where appropriate and create a tailored acne treatment plan designed specifically for your skin.
