Rooibos tea extract – I use this as rooibos tea RS (rice solution) or rooibos tea glycerin, both of which are water soluble. It may help tighten skin and reduce irritation as well as acting as an anti-oxidant and anti-inflammatory. Use either in the cool down phase at 1% to 10%. There is an oil soluble version in sunflower oil (SNO), which you would use in place of the light emollient in this formula.
Please do not use tea you’ve made yourself in any formula as it can cause serious contamination in days. Click here for more on this topic!
