There are hundreds of Vitamin C products available on the market today, all of which promise significant brightening results – but many don’t deliver. Why? Because not all Vitamin C is created equal.

Don’t be misled to think that high percentages of Vitamin C equal a more effective product. The brightening efficacy of a Vitamin C formula isn't all about the quantity. There are two main factors that make Vitamin C products effective: the Vitamin C needs to be highly stable - so that it remains active and efficient, and it needs to be bioavailable - able to get into the skin and work where it’s needed.

Stability: This is Vitamin C’s most well-known shortfall. Traditional forms of Vitamin C are easily oxidized upon exposure to air, heat or water – which can cause the formula to lose its antioxidant power, thus degrading the product's efficacy. You may notice your product turn brown or smell off, this is a sign the Vitamin C is oxidising and losing its power.

Bioavailability: This is also a significant challenge: for Vitamin C to help neutralize free radicals, firm and brighten, it must get to where it’s needed in the skin. If topical Vitamin C products aren't optimized so that the Vitamin C is bioavailable and remains stable, they will produce little to no benefit for the skin.

Dermalogica’s supercharged BioLumin-C formulas are unique, but each one uses our ultra-stable Vitamin C complex to deliver the full power of Vitamin C exactly where it’s needed most for ultimate results. We’ve created formulas that are extremely stable and highly bioavailable, delivering outstanding brightening, firming, and smoothing results.
