Curcuminiods are extracted from Turmeric for their antioxidant and anti-irritation properties. In addition, tetrahydrocurcuminoids are commonly used in combination with other actives to reduce the appearance of dark spots and uneven skin tone. For those familiar with formulating their own DIY skincare regimen, use Tetrahydrocurcuminoids as a solution in your skincare products to enhance your skin refining needs. This ingredient is recommended for advanced DIYers familiar with mixing formulations together. Follow our recommendations below for creating your own product using tetrahydrocurcuminoids.

How to use it
Advanced: This ingredient is recommended for use at up to 0.5% in formulations. We recommend dissolving this ingredient in an oil, ester, or PEG-40 Hydrogenated Castor Oil before adding to creams to avoid a gritty texture. Creams can only handle a finite amount of additional oil, so make your solution with a smaller amount of additional oil/solvent (1-2%). This solution can then be added to a cream at room temperature. When making an emulsion, you can add the tetrahydrocurcuminoids to the heated oil phase.
Quick Tips
Warm 15mL (about 3 tsp) of Rosehip Seed Oil or Squalane in a microwavable safe bowl, in 5 second increments until warm. Stir in the tetrahydrocurcuminoids until dissolved. Add this mixture to you base cream and stir well.Ingredients
