Aqua Bio Technology ASA has been granted a US patent for use of Chaga in cosmetic formulation. The Chaga mushroom grows on birch trees throughout the northern hemisphere. The extract from Chagas mushroom has shown good results on wrinkles and general skin improvement.

The extract from Chagas mushroom can be beneficial for anyone suffering from skin conditions such as acne, allergic reactions, rashes, dermatitis, psoriasis, rosacea and eczema. The US patent secures ABT's use of this ingredient in existing and future cosmetic products and prohibits other players to use this ingredient without a specific license from ABT. From 1 March 2023, Hofseth Biocare ASA, Cosmed Beauty AS and Aqua Bio Technology ASA are co-located in Bygdøy Alle 3 in Oslo.

The co-location will lead to increased synergies between the companies that all have the same main shareholder.
