font-size: 14px;">Hyaluronic acid is an acidic mucopolysaccharide macromolecular substance widely present in the connective tissues of humans and animals. It has important functions in the body such as maintaining water, regulating osmotic pressure, maintaining tissue morphology, as well as lubrication, diffusion barrier and stress buffering. From the age of 25, hyaluronic acid in the human body will gradually be lost. At the age of 30, only 65% of the hyaluronic acid content of the young skin is left. This value is only 25% of the young skin at the age of 50. Hyaluronic acid is lost with age, the skin will gradually lose its elasticity and luster over time , wrinkles and sagging will also occur.</span></p><p><br></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Whether in low humidity or high humidity conditions, sodium hyaluronate has the same high hygroscopicity and can automatically adjust and maintain skin moisture, so it is known as "Key to the fountain of youth". Therefore, it is regarded as an ideal natural moisturizing factor and is widely used in cosmetics to make products suitable for different skin types, climates and environments. The high-molecular sodium hyaluronate can form a breathable film on the skin surface to help the skin lock in moisture, and block the intrusion of foreign bacteria, dust, and ultraviolet rays to protect the skin from harm. Low-molecular sodium hyaluronate can quickly penetrate into the dermis, slightly expand capillaries, promote blood circulation, improve metabolism, promote nutrient absorption of skin cells, and have the functions of reducing wrinkles, enhancing skin elasticity, and delaying skin aging.</span></p></div><div class="box box-element ui-draggable" style="overflow: hidden; margin-top: 20px;"><p style="color: #333333; font-family: 'Segoe UI', SegoeUI, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px;"><span style="font-family: arial, helvetica, sans-serif; font-size: 20px; color: #003366;">Application range of Sodium Hyaluronate 1.5-2.0M DA</span></p><p style="color: #333333; font-family: 'Segoe UI', SegoeUI, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px;"><br></p><p style="color: #333333; font-family: 'Segoe UI', SegoeUI, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px; color: #000000;">Skin care products: cream, lotion, toner, serum, gel, facial mask, etc.</span></p><p style="color: #333333; font-family: 'Segoe UI', SegoeUI, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px; color: #000000;">Cleansing products: facial cleanser, shower gel, etc.</span></p><p style="color: #333333; font-family: 'Segoe UI', SegoeUI, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px; color: #000000;">Hair products: shampoo, conditioner, hair restorer, hair spay, etc.</span></p></div><div class="box box-element ui-draggable" style="overflow: hidden; margin-top: 20px;"><p style="color: #333333; font-family: 'Segoe UI', SegoeUI, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px;"><span style="font-family: arial, helvetica, sans-serif;"><span style="font-size: 20px; color: #003366;">Storage </span><span style="color: #003366; font-size: 20px;">of </span><span style="color: #003366; font-size: 20px;">Sodium Hyaluronate 1.5-2.0M DA</span></span></p><p style="color: #333333; font-family: 'Segoe UI', SegoeUI, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px;"><br></p><p style="color: #333333; font-family: 'Segoe UI', SegoeUI, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px; color: #000000;">Store in cool place.
