What it is
This product is a concentrated solution comprised of amino acids and amino acid derivatives, formulated to support the skin's barrier, elasticity, and moisture balance. It contains 17% amino acids by weight and 5% D-Panthenol to provide hydration and aid in maintaining healthy skin. The product aims to deliver non-greasy hydration and may be combined with other skincare products to reduce its strength if needed.
Key ingredients and their functions
- Propanediol - solvent
- Betaine - humectant
- Sodium PCA - humectant
- Panthenol - moisturizer
- Sodium Lactate - humectant
- Arginine - skin conditioning agent
- Dimethyl Isosorbide - solvent
- Polysorbate 20 - emulsifier
How it works
The amino acids in the product are similar to those found in the skin's natural moisturizing factors and contribute to skin barrier support and elasticity. The presence of D-Panthenol, a pro-vitamin B5, enhances surface and below-surface hydration. Propanediol and Dimethyl Isosorbide act as solvents, helping to deliver active ingredients more effectively. Humectants like Betaine, Sodium PCA, and Sodium Lactate help attract and retain moisture in the skin. Arginine functions as a skin conditioning agent, while Polysorbate 20 acts as an emulsifier, ensuring that the ingredients mix well together. This combination of ingredients is designed to offer hydration support, improve the skin's moisture balance, and maintain healthy skin appearance.
