Yilian is a brand of hyaluronic acid raw material factory Freda Biopharmaceutical. Freda focuses on the research and development of sodium hyaluronate and is the world's largest supplier of hyaluronic acid. Its hyaluronic acid hydrating spray has achieved good sales at an affordable price and a delicate spray.

Naturally, the hyaluronic acid hydrating spray also uses sodium hyaluronate, with polyol and sea silt extract, which is more moisturizing on the face and has a good moisturizing effect. The preservatives are chlorphenesin and methylparaben, which may cause skin irritation, while methylparaben is a paraben preservative with poor safety and is recommended to be avoided for sensitive skin.

The special feature of the hyaluronic acid hydrating spray is that it uses binary packaging, i.e. the material and propellant are separated, which makes the spray more dense and lighter than other aerosol bottle-packed products. Ordinary aerosol spray is easy to be unable to spray out the remaining liquid due to insufficient air pressure in the later stage, while hyaluronic acid hydrating spray has no such problem and can basically be used up completely. However, the bottle is relatively heavy, and the water droplets in the small bottle spray are coarser than in the large bottle. Hyaluronic acid spray is priced at 39-79 yuan, and there are two specifications: 100ml and 200ml.
