The data is brutal. Pterostilbene gets into the skin nearly four times faster than standard Resveratrol. You get vastly superior anti-aging performance at a much lower active dosage.<\/p>

You must pre-dissolve it. Weigh out your formulation\u2019s Propanediol, Butylene Glycol, or Ethoxydiglycol in a side beaker. Add the Pterostilbene powder. Heat it gently to 60 degrees Celsius. The crystals will melt into a perfectly clear, golden liquid.<\/p>

Add this active liquid directly into your lipid phase right before you turn on the homogenizer. Keep your final emulsion mildly acidic. Pterostilbene thrives in a pH environment of 5.0 to 6.0.<\/p>
