Teosyal® – Application & Products
Teosyal® hyaluronic acid products are manufactured by the Swiss company Teoxane in Geneva, which was founded in 2003. The hyaluronic acid is cross-linked with BDDE and was CE certified in 2004. The hyaluronic acid gel range, also known as “Resilient Hyaluronic Acid” (RHA), is monophasic. The hyaluronic acid chains are longer and have a low degree of cross-linking of 1.9 to 4.0 percent. As a result, the RHA product range is said to have high elasticity and adapt well to the movements of the facial muscles.
