During a UK heatwave, many people turn to refrigerating their skincare for a cooling sensation, but experts warn this practice could damage products and harm skin health. Andrea Pfeffer, skin expert and founder of London clinic Salon C. Stellar, told Metro that unless a brand specifically instructs refrigeration, the formula was not designed for cold storage.
Why refrigeration can destabilise skincare
Pfeffer explained that products are stability tested at conditions set by the manufacturer, typically around 25 degrees Celsius. The cold can destabilise the formulation, dull its effectiveness, and even cause ingredients to separate. This applies to balms, facial oils, clay masks, and acids, according to Ikè Muotoh, founder of African botanical bodycare brand Dibia. He noted that he keeps his gua sha tool in the fridge for de-puffing, but not his skincare products.
Alternatives for a refreshing routine
Instead of refrigerating products, Pfeffer recommends lightweight serums like Esse's Probiotic Serum (£78) or RAESO's Morning Dew Vitamin C (£110). These provide hydration without heaviness, ideal for sweaty skin. She emphasises that broad-spectrum SPF is non-negotiable during a heatwave, and advises against over-exfoliating when skin is stressed. For evening routines, she encourages continuing vitamin A products like Medik8 Crystal Retinal (from £50), saying: "Don't retire your vitamin A for summer."
Face mists and body oils as cooling aids
For on-the-go refreshment, Pfeffer suggests a well-formulated face mist rich in humectants and emollients, such as Byoma's Balancing Face Mist (£11.99), which contains ceramides, allantoin, and probiotics. Muotoh advises using lighter body oils on damp skin after a cool shower, citing Dibia Sacred Radiance Body Oil (£45) with baobab, marula, and manketti oils for deep nourishment without greasiness.
Sunburn and heat rash care
If sunburn or heat rash occurs, Pfeffer recommends avoiding acids, vitamin A, and fragrance. Instead, cool the area with lukewarm or cool water, pat dry, and apply a ceramide cream like Heliocare Aftersun UV Repair (£24.99), which contains vitamin E, panthenol, and pentavitin. She warns against alcohol-laden after-sun gels that can dry out skin.
