Tensage uses its SCA Repair Technology to slow and even reverse the signs of aging in its Intensive Ampoules, giving you a 40 on the Repair Index, the highest score possible. With this ageing cream, results are seen in just one week. SCA stands for the naturally existing Substance excreted from the Cryptomphalus Aspersa, a snail. After an injury, this type of snail secretes this substance to repair its skin in just one day’s time.
