What is Sodium hyaluronate?
Sodium hyaluronate is the salt form of an important glycosaminoglycan called hyaluronic acid (HA) or hyaluronan. Glycosaminoglycans are polysaccharides sugars molecules that are linked by proteins. These water-attracting molecules bind to water to create a viscous substance that fills the space between collagen and elastin fibres in the dermis—providing fullness and radiance to the skin. The amount of hyaluronic acid declines with age. Aside from the skin, it is also found in abundance in various tissues of human and animal species, including the joint fluids, vitreous humor of the eyes, and neural tissues.
Cosmetic and Clinical Applications
Sodium hyaluronate acts as a tissue lubricant; its viscoelastic property provides mechanical protection for tissues and cell layers. It facilitates transport of molecules, such as growth factors and structural proteins to a site of action. HA also plays a role in wound healing and ...
Lip augmentation is quickly becoming a popular cosmetic procedure to alter or enhance the appearance of the lips. Injectable soft tissue fillers containing hyaluronic acid (HA) are the most common method used for lip contouring. Hyaluronic acid is a naturally occurring substance with fewer allergenic aspects. The temporary and reversible effects it provides make it an ideal filler even for first-time recipients. The water-attracting molecules of HA creates a plumping effect, visibly increasing the volume of the lips.
Ageing, genetic factors, cigarette smoking, and photodamage contribute to volume loss in the perioral area. Lip wrinkles, genetically thin lips, and cosmetic asymmetry are some of the issues that can be improved by lip augmentation. This can be done surgically or through a minimally invasive procedure such as dermal filler injectable.

What are bags under eyes?
Bags under eyes often manifest as mild swelling or puffiness under the eyes. Although it’s a common cosmetic concern, it is harmless. However, persistent and severe swelling can also be caused by serious medical conditions, such as nephrotic syndrome and superior vena cava obstruction. Under eye bags are due to inflammation that results to fluid buildup around the eyes. When the fat that supports the eyes sags into the lower eyelid, it also causes the lids to appear swollen and puffy.
Common causes of bags under eyes
Normal ageing process causes the skin and underlying tissues that support the eyelids to weaken.
Lack of sleep
Inadequate sleep causes the blood vessels under the eyes to dilate that leads to pooling of blood and retention of fluid in these areas.
Cigarette smoking and alcohol use
These cause stress, fatigue, and hormonal imbalances that can lead to fluid retention.
Some people are just more susceptible to und ...
