Beauty Tips For Body Care
As I've been learning more about cosmetic chemistry, I've got interested in penetration enhancers and started to really look for them on ingredients list. Does anyone else do this?If you're not a huge cosmetic chemistry nerd like I am, penetration enhancers do what they say they do - they enhance the penetration of substances into the skin. Some of the more common ones: isopropyl myristate; dimethyl sulfone and dimethyl isosorbide; alcohols such as butylene glycol, ethoxydiglycol, and bisabolol; urea (in 5%+ concentrations); oils like jojoba oil, tea tree oil, and olive oil/other high oleic acid oils. I've done some reading about this on Google Scholar, but also find this thread illuminating.I've realised that Klairs Supple Preparation is basically unique in having dimethyl sulfone so high up the INCI. I always thought it was a bit expensive for a toner, but I'm reconsidering buying it now. I've also realised that The Ordinary includes penetration enhancers in quite a few of their products; there's dimethyl isosorbide and ethoxydiglycol in the Niacinamide and the Azelaic Acid, while the Granactive Retinoid in Squalane (both 2% and 5%) has dimethyl isosorbide, jojoba oil, and bisabolol. I've been using Geek & Gorgeous A-Game for a while and really like it, but now I'm considering switching over to TO. If it ever comes back into stock, that is.
