Stem Organics are paraben and phenoxyethanol free
Stem Organics preservative of choice is sodium hydroxy methylglycinate. This is an amino acid and independent tests have found it to be non-toxic by skin absorption and non-mutagenic (does not damage the DNA or possess the potential to damage chromosomes). However, a test on a guinea pig did reveal it to be a potential allergen. In Europe it is permitted at concentrations of 0.5%.
Anyway, if that's as bad as Stem gets, I'll take it. For a light summer serum Fresh Start Serum ($65) is an enjoyable experience. The appellation 'fresh' is really appropriate. It will help you start your morning off with a little spring in your step. It is also packed full of antioxidants including rosehip oil (which one reader commented is even better than argan oil), ginko, green tea, niacinamide (a vitamin B with a good pedigree for repairing skin cells) and sea buckthorn. Like all other Stem products, it has their signature combo of kakadu (brimming with enough vitamin C to put an orange to shame), tasmanian kelp, pomegranate and gotu kola.
