<p data-start="82" data-end="751">The Ordinary Amino Acids + Vitamin B5 Hydration Serum is a concentrated, water-based facial treatment formulated to support deep hydration, barrier strength, and overall skin comfort through skin-identical components. This serum is designed to closely resemble the natural composition of amino acids found within the skin’s own Natural Moisturising Factors, allowing it to integrate seamlessly with the skin’s surface and support balanced hydration. Its lightweight, fluid texture spreads easily and absorbs quickly, delivering moisture without heaviness or residue, making it suitable for daily use across a wide range of skincare routines.The formulation contains a high total concentration of amino acids and amino acid derivatives, helping to improve the skin’s ability to retain moisture and maintain osmotic balance. These components play a role in supporting skin elasticity and smooth desquamation, which contributes to a softer, more refined surface appearance over time. Vitamin B5, included in the form of panthenol, enhances both surface and below-surface hydration while supporting skin comfort and recovery. Together, these ingredients help improve the look and feel of dehydrated or stressed skin, promoting a healthier and more resilient complexion with continued use.Designed for consistent, long-term use, this serum focuses on strengthening the skin’s hydration framework rather than offering temporary cosmetic effects. It layers easily with other serums, moisturizers, and treatments, making it adaptable to both minimal and advanced skincare routines. With regular application, the skin appears smoother, more supple, and better balanced, reflecting improved moisture retention and barrier support through a formulation that prioritizes skin-identical hydration and functional simplicity.</p> <p data-start="1928" data-end="2414"><strong data-start="1928" data-end="1944">Key Features</strong><br data-start="1944" data-end="1947" /> This hydrating serum is formulated with a 17% concentration of amino acids and amino acid derivatives to closely mimic the skin’s natural moisturizing system and support barrier integrity.
