Key Moisturizing Ingredients for an Overnight Mask

Based on the ingredient list you provided for the overnight mask, here are the key ingredients that contribute to hydration, reducing water loss, and are suitable for a leave-on treatment. Many of these are available on the MySkinRecipes website.

Available Key Ingredients on MySkinRecipes:

• Glycerin: A highly effective and common humectant that draws moisture into the skin.
• Butylene Glycol: Acts as a humectant and solvent, helping other ingredients penetrate the skin.
• Trehalose (TreMoisture™): A disaccharide that helps protect skin cells from dehydration and improves hydration.
• Beta-Glucan: Known for its moisturizing, soothing, and skin-strengthening properties.
• Natural Moisturizing Amino Acids (e.q. Prodew 400): This blend mimics the skin's natural moisturizing factors, providing essential hydration. It includes several amino acids found in your list, such as Glutamic Acid, Lysine, Serine, Alanine, Arginine, and Threonine, as well as Sodium PCA.
• Sodium PCA: A component of the skin's natural moisturizing factor, helping to maintain hydration.
• 1,2-Hexanediol: Functions as a humectant and also has preservative-boosting properties.
• Mannitol: A sugar alcohol with moisturizing and soothing benefits.
• Cyclopentasiloxane: A lightweight silicone that provides a smooth feel and forms a breathable barrier to reduce moisture loss.
• Dimethicone: Another silicone that creates a protective layer on the skin, enhancing softness and preventing water evaporation.
• Hydroxypropyl Bispalmitamide MEA (Pseudo-Ceramide 104): A ceramide-like ingredient that helps strengthen the skin barrier and improve moisture retention.

While these also have moisturizing properties, the available ingredients listed above are excellent choices for creating a hydrating overnight mask.

Creating Your Own Formula:

To create a similar hydrating overnight mask, focus on combining humectants like Glycerin, Butylene Glycol, Trehalose, Natural Moisturizing Amino Acids (including Sodium PCA), 1,2-Hexanediol, and Mannitol with emollients/film-formers such as Cyclopentasiloxane and Dimethicone, and barrier supporters like Hydroxypropyl Bispalmitamide MEA. The exact percentages would require formulation expertise and testing, but these key ingredients provide the core moisturizing and occlusive properties needed for an effective overnight treatment.
