The application of a moisturiser is a crucial step in a skincare routine for all skin types, even for oily skin , contrary to popular belief, in order to maintain skin hydration and keep the skin looking healthy. Although the skin has its own natural hydration system with sebaceous glands that secrete sebum to create, along with sweat, a protective layer (hydrolipidic film) against external conditions, dryness, dehydration and microbial attacks, most skins need additional hydration after what external factors inflict on the skin.
Is there a difference between day cream and night cream? Lighter in texture, the function of a day cream is to maintain skin hydration and protect the epidermis from external elements during the day, while the night cream, being thicker, aids in skin regeneration and enhances skin hydration. Moreover, it typically contains active ingredients that may increase sensitivity to sunlight (retinol, AHA, etc.).
Moisturising products have thus been designed to increase the water content in the stratum corneum, reduce the risk of developing dry skin, contribute to supple and comfortable skin, and help maintain the integrity of the skin's protective barrier. Indeed, its texture leaves a slight hydrophobic film on the skin. It is therefore recommended to apply the moisturiser, suited to your skin type, after the serum and targeted treatment to limit transepidermal water loss, and seal in the hydration and active ingredients contained in the serums to ensure better penetration into the skin. In the evening, the moisturiser constitutes the final step of a facial routine. However, during the day, an additional step is necessary before concluding your skincare routine.
Targeted moisturising formulas with the addition of specific active ingredients (vitamin C, zinc, peptides, etc.) have been developed to help address various skin conditions you may have, thus going beyond the simple function of hydrating the skin.
Night serum, vegetable oil, night mask: as a replacement or in addition to moisturising cream?
You could potentially substitute your traditional moisturising product with a night serum rich in lipid extracts or a vegetable oil, as the final step in your night-time routine. Much like moisturisers, they help maintain a good level of skin hydration thanks to fatty acids. However, some may feel the need to apply an additional moisturising treatment. Before or after the moisturiser? It all depends on the texture. It is also possible to apply a night mask over the entire face, on top of the serum, which can then work throughout the night.
