A common misconception is that moisturiser can be substituted for rosehip oil, which just isn’t able to support your skin’s healthy barrier function. Then there’s the very contentious issue of parabens. Companies have started substituting parabens for natural’ preservatives that are less effective and more harmful due to their inconsistent and limiting effectiveness in preventing bacteria growth and oxidation. The skincare we recommend in our clinic contains no more than 0.01 per cent parabens – none of which is absorbed through to the bloodstream. Look at PubMed and other trusted sources for info on a particular ingredient if you are concerned.
