Use shower oils or cleansing oils to wash the skin gently and remove makeup or sunscreen, while preserving and protecting the skin's protective barrier against drying out.

The idea of using oil-based cleansers to preserve the skin barrier is scientifically very robust, as lipids gently solubilize sebum and sunscreen filters without stripping the skin. A randomized controlled trial (RCT) led by Jan Kottner in 2017 confirms that the regular use of shower oils significantly improves hydration and reduces transepidermal water loss compared to conventional foaming cleansers. These oily formulas help avoid the irritating effect of traditional surfactants, thereby preserving the natural suppleness of the cutaneous envelope. However, the term "rebuilding" the lipid barrier is a bit of an exaggeration for a rinse-off product, which simply leaves a light protective film on the surface rather than recreating new lipids in the deeper layers. Furthermore, while this method is ideal for dry skin, individuals with oily-prone skin must ensure they choose non-comedogenic oils to avoid clogging pores.
