In the midst of a scorching summer, Londoners are grappling with the challenges of soaring temperatures and humidity. As the city's residents perspire profusely, a common concern arises: how can one prevent breakouts during these sweltering heatwaves? Dr. Aamna Adel, a consultant dermatologist and founder of rhute, offers invaluable insights into this very question. According to Dr. Adel, sweat itself is not the culprit behind acne. Instead, the issue lies in the combination of sweat, excess sebum, sunscreen, makeup, and environmental debris, which can clog pores and trigger irritation in sensitive skin. The high humidity in London exacerbates this problem, as sweat lingers on the skin for longer periods, increasing the risk of breakouts. Dr. Adel emphasizes that heat stimulates increased sebum production, and when this oil combines with sweat, the risk of clogged pores and acne escalates. Moreover, the frequent touching and wiping of the face in hot weather can introduce additional irritation. It's crucial to understand that not all skin issues during heatwaves are acne. Heat rash, for instance, can develop when sweat ducts become blocked, resulting in small, itchy or prickly bumps that may be mistaken for acne. Dr. Adel advises against the common misconception that abandoning moisturizers and sunscreens is the solution to oily skin or breakouts. She clarifies that both products are essential, even during heatwaves. Lightweight, non-comedogenic moisturizers help maintain a healthy skin barrier, reducing irritation and supporting proper skin function. Similarly, sunscreen is vital, as UV exposure can worsen post-inflammatory hyperpigmentation, accelerate skin aging, and increase the long-term risk of skin cancer. Dr. Adel recommends focusing on choosing lightweight formulations that are enjoyable to use consistently. When adapting skincare routines for hot weather, Dr. Adel suggests making them lighter. If richer creams feel uncomfortable, switching to lightweight gels or lotions can provide comfort without compromising hydration. She emphasizes the importance of consistent cleansing to remove sweat, sunscreen, and makeup, and maintaining a regular skincare routine. For those with acne or seborrhoeic dermatitis, Dr. Adel advises continuing prescribed treatments rather than discontinuing them due to weather changes. Salicylic acid and niacinamide are highlighted as effective ingredients for managing summer breakouts. Salicylic acid, being oil-soluble, can penetrate 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 by pairing active ingredients with lightweight moisturizers rather than attempting to dry the skin out. Balancing SPF, sweat, and makeup is crucial to preventing clogged pores. Dr. Adel suggests 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 recommended practices. She advises against skipping sunscreen and suggests rethinking the additional cosmetic layers on top rather than the SPF itself. Dr. Adel's golden rule for preventing summer breakouts is to support the skin barrier with a simple, consistent routine, gentle cleansing, lightweight hydration, and daily sunscreen. She emphasizes that healthy skin is better equipped to handle heat, humidity, and excess oil compared to skin that has been stripped and irritated. By following these expert tips, Londoners can navigate the challenges of sweaty city summers with confidence, ensuring their skin remains healthy and breakouts at bay.
