How does C-Tetra Advanced compare to Super C Ferulic?Updated 24 days ago

Both C-Tetra Advanced and Super C Ferulic are high strength Vitamin C serums, and therefore we recommend choosing just one in your regime. 

Super C Ferulic is an intense brightening serum containing 30% ethylated ascorbic acid, a form of vitamin C. It is recommended for mature skin types showing advanced signs of sun-induced ageing, such as significant hyperpigmentation. Due to its potency, please note that it is not suitable for sensitive skin, and patch testing is required. It has an oil-like texture that absorbs quickly into the skin.

C-Tetra Advanced is a brightening, age-defence serum containing 20% tetrahexyldecyl ascorbate, an ultra-gentle form of vitamin C. Its creamy gel formula is boosted by super antioxidant acetyl zingerone & phyto exosomes for advanced age defence and fast brightening results. If you have sensitive skin but would still like to use a high-strength vitamin C, we would recommend C-Tetra Advanced.
