I tried the Nakery products and immediately went back to Korres.  Her jars leak especially the ones with oil.

The THDA vitamin C ingredient (it's an oil) is not an inexpensive one at all. Most serums which contain it are on the expensive side. But the good thing about THDA is that it works at very low concentrations. From LotionCrafter dot com:

 

  • "At 0.1% reduces melanin synthesis by 80%
  • At 10% eliminated age spots in 16 weeks
  • At 3% in vivo reduces Delta-L value by 15% vs. placebo (22 people), a way to measure whitening effect
  • Increases collagen synthesis at least twice as much as ascorbic acid
  • Protects the cells against UV-B better than other esters of Vitamin C"
