By adding Synovea® HR (Hexylresorcinol) and Synovea® EL (Ethyl Linoleate) to the skin-friendly emollient Caprylic/Capric Triglycerides Sytheon has created an elegant, easy-to-use and very cost-effective new synergistic skin lightening blend – Asyntra® SL. Ethyl Linoleate is a very good solubilizer for HR and is a stable form of Linoleic acid. Linoleic acid is an essential fatty acid, a precursor of ceramides and a major component of skin lipids. EL is clinically proven to lighten UV-induced skin pigmentation by accelerating post-translational proteolytic degradation of tyrosinase.

Sytheon limited was purchased in November 2024 and their line of products including this one is now available within the Hallstar Beauty portfolio.
