Lubricants, often referred to as emollients or moisturizers, are scientifically validated for supporting and treating dry and/or flaky skin. These products are commonly used in dermatology to restore the skin’s barrier function, reduce transepidermal water loss, and improve hydration. Scientific evidence demonstrates that lubricants, which can include mineral oil, petrolatum, dimethicone, and various plant-based oils, form a protective layer on the skin surface, preventing moisture loss and providing a smoother appearance.

Numerous clinical studies and dermatological guidelines recommend lubricants for conditions such as xerosis (dry skin), atopic dermatitis, and psoriasis. For example, the American Academy of Dermatology and the British Association of Dermatologists both endorse regular use of emollients as first-line management for dry and flaky skin. A 2012 systematic review in the Journal of the European Academy of Dermatology and Venereology confirmed their efficacy in moisturizing and improving skin barrier function.
The mechanism of action is well understood: lubricants fill spaces between desquamating skin cells with lipids, thus reducing roughness and scaling. They may also contain humectant ingredients (like glycerin or urea) that attract moisture.
In summary, the use of lubricants for dry and/or flaky skin is strongly supported by scientific evidence and is a mainstay of dermatological care.
