Radiant-C MD Serum 12% Vitamin C

Vitamin C has a reputation for going off, and for stinging. This formula sidesteps both.

The active is 3-O-ethyl ascorbic acid at 12% — a stabilised derivative rather than pure L-ascorbic acid. Pure vitamin C oxidises in the bottle, turning yellow then brown, and by the time most people notice they have been applying something inert for weeks. This one holds its strength, and it sits at a skin-friendly pH rather than the sharply acidic one high-strength L-ascorbic requires.

Ferulic acid is included to extend its antioxidant life once on the skin.

It is also a light, water-based serum — no silicone, no oil, nothing to make an oily face oilier.

Which vitamin C to choose

Both use the same stabilised vitamin C. The difference is focus:

  • Radiant-C MD — single-minded, at a declared 12%, with ferulic acid and nothing competing for room in the formula. Choose this for maximum vitamin C and antioxidant protection.
  • Glowgenic C+T — the same vitamin C with niacinamide, acetyl glucosamine, licorice root and turmeric alongside it. Choose this if uneven tone is the main concern, or if a straight vitamin C has irritated you before.

How to use

Morning, on clean skin, before moisturiser and sunscreen. Vitamin C and sunscreen belong together: one neutralises the damage the other does not block.
