Hyaluronic Acid Serum Powder is a cosmetics-grade ingredient designed for skin hydration and moisture support. This product contains both low and high molecular weight hyaluronic acid, allowing for multi-layer hydration: the low molecular weight penetrates deeper layers of the skin, while the high molecular weight forms a surface film to help retain moisture. The powder is water soluble and vegan, making it suitable for inclusion in a variety of personal care formulations. It can be dissolved in water or water-based liquids to create custom serums, toners, or moisturizers. The 200-gram quantity offers flexibility for regular use in DIY skincare preparations or for blending into existing products such as creams, lotions, and sheet masks. This ingredient is intended for individuals seeking to boost the hydrating properties of their skincare routine without relying on pre-formulated, single-use products. The powder format allows for controlled dosage and integration into water-phase formulations. It is important to follow recommended usage rates and dissolve the powder thoroughly before application. As a cosmetic grade material, it is intended for external use only. The product contains no animal-derived ingredients and is suitable for those following a vegan lifestyle. Potential users include formulators, home crafters, and anyone interested in customizing their skincare hydration. Proper storage in a cool, dry place is advised to maintain product stability.
