Skin flooding, a viral TikTok trend involving layering multiple hydrating products, has split dermatologists. Some warn it risks damaging the skin's natural barrier, while others praise it for encouraging hydration.
Skincare experts at Absolute Collagen have cautioned that the hack could have adverse effects, including dry, itchy skin. Dr Dave Reilly added: 'The layering of products is simply not necessary to achieve hydrated skin. In fact, it could actually be counterproductive.' He noted that mixing certain ingredients, such as retinoids with acids, can harm the skin barrier.
However, other dermatologists endorse the trend when done correctly. Dr Marisa Garshick outlined four key steps: cleanse with a gentle cleanser on damp skin, apply a hydrating serum with hyaluronic acid or glycerine, follow with a serum containing niacinamide or polyglutamic acid, and finish with a moisturiser to lock in hydration.
Dr Garshick suggested that those with very dry skin can repeat the routine twice daily, and recommended using sunscreen in the morning. The hashtag #skinflooding has amassed 43 million views on TikTok, while #glowyskin has been viewed 120 million times in the past year.
