Frequently Asked Questions
VITAMIN C

What does Vitamin C do for the skin?

Vitamin C is a potent antioxidant that protects skin from free radical damage caused by UV, pollution, and other environmental stressors. It also brightens dull skin, fades dark spots, promotes collagen production, and helps even skin tone — making it one of the most multitasking anti-ageing ingredients available.

What is the difference between Vitamin C and Vitamin Cg?

Pure Vitamin C (L-Ascorbic Acid) is the most potent and fast-acting form, but can be unstable. Vitamin Cg (Ascorbyl Glucoside) is a more stable derivative that converts to pure Vitamin C once absorbed — offering excellent antioxidant and brightening benefits with superior formulation stability.

When should I use Vitamin C skincare?

Vitamin C serums like Liftactiv 16% Vitamin C Serum are best applied in the morning to maximise antioxidant protection against daytime UV and pollution exposure. Always follow with SPF. Moisturisers containing Vitamin Cg can be used morning and evening.

Can I use Vitamin C with hyaluronic acid?

Absolutely. Vitamin C and hyaluronic acid are highly complementary — Vitamin C provides antioxidant protection and brightening, while hyaluronic acid hydrates and plumps. Many Vichy products combine both for enhanced efficacy.
