Frequently Asked Questions
How is this different from Triology? Triology uses fresh L-ascorbic acid — the most potent but least stable form of Vitamin C. Tetra-C uses a stable, oil-soluble form that doesn't need replacing monthly, making it a lower-maintenance way to add Vitamin C into your routine, or to layer alongside Triology for extra brightening.
Can I use Tetra-C and Triology together? Yes — many customers use Triology in the morning and Tetra-C at night, or add a few drops of Tetra-C into their HydraSilk moisturiser for an extra glow boost.
How often should I use it? Apply nightly for best results, or a few times a week if you're introducing it alongside other actives.
