With next week’s heatwave approaching, searches for “retinol and sun exposure” have surged by 4,250% and “how much retinol to use” by 1,100% in the past 30 days. These figures show that more people are questioning how to adapt their skincare routine as temperatures climb.
To offer clarity, Cult Beauty has partnered with pharmacist and founder of The Derma Lab, Elizabeth Japal, to explain what your skin needs during summer and why certain ingredients, including retinol, should be paused when the sun is strong.
“As the seasons change, so do your skin needs,” says Elizabeth. “In the warmer weather, skin tends to be oilier, sweat more, and is exposed to high levels of UV and environmental stress. This means you can usually pare back heavier products and focus on lightweight hydrating and strong sun protection. SPF becomes your top priority, and formulas that support the skin barrier are essential. If you don’t adapt your routine, you may experience clogged pores, irritation, or premature aging.”
If you are planning time in the sun, Elizabeth advises rethinking the use of active ingredients like retinol. “If you’re heading abroad or expecting intense sun exposure, it’s wise to take a short break from retinol to avoid irritation and overexposure.” Known for its role in smoothing fine lines and boosting collagen, retinol can become problematic when combined with strong UV rays. Elizabeth adds, “Retinols, AHAs and BHAs can make skin more photosensitive. You don’t need to ditch them forever, but if you’re on a beach holiday or spending hours in direct sunlight, now’s the time to give your skin a break.”
To maintain calm and protected skin during summer, Elizabeth shares some essential skincare guidance.
Use a broad spectrum SPF50 and reapply every two hours. Opt for a water or gel based moisturiser with hyaluronic acid that is oil free and noncomedogenic. Include antioxidants in your routine such as vitamin C, niacinamide and green tea extract to help defend the skin from UV damage and environmental stressors. These do not replace sunscreen but can help build skin resilience. A lightweight antioxidant serum in the morning works well alongside SPF. Cleanse your face twice a day with a gentle non-stripping cleanser. A cooling face mist can help refresh your complexion throughout the day.
Elizabeth also notes a few habits to avoid. She cautions against using retinols when sun exposure is high. “It becomes risky when paired with strong UV rays.” She also advises not to overlook your lips, neck and hands when applying SPF. Choose nourishing lip balms that offer protection and remember to reapply your body SPF regularly. Keeping hydrated is also essential. Drink at least two litres of water daily. Strong exfoliating solutions should be avoided during sunny holidays. Stick to gentle, moisturising steps to avoid irritation.
