The Complex

Together with our partner labs, we’ve developed a potent vitamin C complex with three stabilised forms of vitamin C, each with individual benefits:

  • Stay-C® 50 (sodium ascorbyl phosphate)
  • L-VCG (ascorbyl glucoside)
  • Specwhite VCE (3-O-ethyl ascorbic acid)

Stay-C® 50

Has a proven conversion into ascorbic acid - vitamin C's purest form - once it has penetrated the skin's surface and is the only derivative with a use level of up to 15%.


Is metabolised into ascorbic acid more gradually on contact with the skin compared to other derivatives, giving it a unique time-released effect - you'll experience the benefits for longer.

Specwhite VCE

An ethered derivative, meaning it is both hydrophilic (water-loving) and lipophilic (oil-loving), which results in better skin penetration compared to ascorbic acid.

The Results

The upgraded complex stabilises the formula, slowing the oxidation rate right down and making it less likely to destruct than pure ascorbic acid. It means we’ve been able to deliver a higher concentration of vitamin C without compromising stability and effectiveness. The higher concentration of vitamin C means that you’ll see brighter, more even-toned skin than ever before, and the stable formula means it’s long-lasting, both in terms of efficacy on skin and shelf-life duration.
