Summer acne flare-ups could be linked to what you eat, says a dermatologist

Summer and acne breakouts tend to go hand in hand for many people, with flare-ups becoming a near-inevitable part of the season. Whilst heat is often blamed as the primary culprit, dermatologists point out that diet plays a significant role too.

HT Lifestyle spoke to Dr B L Jangid, dermatologist and hair transplant surgeon at SkinQure Clinic, New Delhi, who decoded the relationship between summer eating habits, excess oil production, and acne-prone skin. He offered an important caveat upfront:

"Though there is no scientific evidence that eating certain foods can cause acne, they can exacerbate the problem if you already have acne-prone oily skin, triggering breakouts."

Foods that may aggravate acne in summer

Sugar

Dr Jangid explained that refined carbohydrates found in sugary foods cause rapid blood sugar spikes, which in turn generate elevated insulin levels.

Higher insulin can stimulate excess sebum production and inflammation, ultimately leading to blocked pores. Foods such as ice cream, kulfi, and sweetened drinks are therefore best avoided by those with acne-prone skin.

Mangoes

Mangoes do not directly cause acne, but Dr Jangid cautioned that they carry a high natural sugar content and a high glycaemic index, which can lead to blood sugar spikes when eaten in large quantities:

"Well, mangoes do not directly cause acne, but they are naturally high in sugar and have a high glycemic index, which can lead to sugar spikes if consumed in excessive amounts."

Elevated insulin levels may in turn prompt the oil glands to produce greater quantities of sebum, heightening the risk of breakouts.

Oily, fatty, and spicy food

Dr Jangid noted that fatty foods — commonly referred to as junk food — are laden with oil, processed carbohydrates, and high caloric content, all of which can drive bodily inflammation and disrupt hormonal balance, contributing to acne.

Those with acne-prone skin are best advised to steer clear of such foods. Spicy food presents a separate concern in summer: it can raise body heat, leading to increased perspiration, which may encourage bacterial growth, skin irritation, and worsening acne.

Dairy products

Several studies over the years have identified an association between milk products and acne. Milk has been shown to raise insulin levels, which can result in heightened sebum production and may aggravate existing acne.

Protein supplements and whey protein

Research suggests that whey protein can elevate levels of insulin-like growth factor 1 (IGF-1), a hormone that stimulates oil production and may contribute to acne development.

What to eat instead

Dr Jangid recommends replacing the above with cooling foods such as watermelon, cucumber, courgette, oranges, berries, and leafy vegetables.

Maintaining a consistent skincare routine and drinking adequate water throughout the day are equally important.

In cases of severe acne flare-ups, home remedies should be avoided, and no products should be applied without consulting a qualified professional first.
