How to Prevent Summer Breakouts During Heatwaves | Dermatologist Tips (2026)

In the midst of a scorching summer, Londoners are grappling with the challenges of managing their skin in the face of soaring temperatures and humidity. As the city's residents perspire profusely, the question arises: how can one navigate the delicate balance between staying cool and maintaining a clear complexion? Dr. Aamna Adel, a renowned consultant dermatologist and founder of rhute, offers invaluable insights into this conundrum. According to Dr. Adel, sweat itself is not the culprit behind breakouts; rather, it's the combination of sweat, excess sebum, sunscreen, makeup, and environmental debris that can lead to clogged pores and irritation, particularly for those with sensitive skin. The intense humidity in London exacerbates this issue, as heat stimulates increased sebum production, and humidity prolongs the residence time of sweat on the skin, creating an ideal environment for breakouts.

One of the most common misconceptions is the notion that abandoning moisturizer and sunscreen is a viable solution during hot, sweaty weather. Dr. Adel clarifies that both are essential, even in the sweltering heat. She emphasizes the importance of a lightweight, non-comedogenic moisturizer to maintain a healthy skin barrier, which is crucial for reducing irritation and ensuring proper skin function. Similarly, sunscreen should not be overlooked, as modern formulations are designed to be lightweight and non-comedogenic, offering protection without exacerbating acne-prone skin. Dr. Adel advises against over-cleansing or skipping moisturizer, as these actions can compromise the skin's barrier, making it more reactive and susceptible to irritation.

When adapting skincare routines for the summer, Dr. Adel suggests a few key adjustments. She recommends using a lightweight gel or lotion instead of richer creams, as these can provide comfort without sacrificing hydration. Gentle cleansing is paramount, ensuring that sweat, sunscreen, and makeup are thoroughly removed in the evening. Consistency in skincare routines is vital, especially for those with conditions like acne or seborrhoeic dermatitis. Dr. Adel advises against abruptly changing products, as consistency often yields better results.

In the quest for clear skin during the summer, certain ingredients shine as effective allies. Salicylic acid, being oil-soluble, penetrates pores to reduce congestion and excess oil. Niacinamide, on the other hand, regulates sebum production, supports the skin barrier, and possesses anti-inflammatory properties. Dr. Adel underscores the importance of maintaining a healthy skin barrier, suggesting that active ingredients should be paired with lightweight moisturizers rather than attempting to dry out the skin.

The challenge of balancing SPF, sweat, and makeup without clogging pores is a common concern. Dr. Adel recommends starting with a lightweight, non-comedogenic sunscreen that is enjoyable to wear and reapplying it regularly. Simplifying makeup routines and gently blotting sweat with clean tissues before reapplying sunscreen are also advised. She emphasizes that sunscreen should never be skipped, and any concerns about congestion should be addressed by reevaluating cosmetic layers rather than the SPF itself.

In conclusion, Dr. Adel offers a golden rule for preventing summer breakouts: don't fight your skin. Instead, focus on supporting your skin barrier with a simple, consistent routine, gentle cleansing, lightweight hydration, and daily sunscreen. By embracing these practices, your skin will be better equipped to handle the challenges of heat, humidity, and excess oil, resulting in a clearer and healthier complexion.
